Pith's one-line read One open-source framework unifies high-resolution emission and transmission retrievals and shows detrending choices change abundances.
desk verdict Open-source unification of HRCCS retrievals in POSEIDON is real and useful; the α≈0.5 offset deserves fuller quantitative treatment, but the paper should be peer reviewed. read the letter →
The pith
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
The reading
What carries the argument
The load-bearing device is fast filtering: after detrending, a low-rank basis $U$ describes the telluric, stellar, and instrumental background in each spectral order; every trial model $M$ is then filtered by projecting it out of that basis, $M' = U(\Lambda U)^\dagger (\Lambda M)$, where $\Lambda$ weights pixels by their time- and wavelength-dependent uncertainties. Because $U(\Lambda U)^\dagger \Lambda$ is independent of the model, it is computed once per order and reused across the hundreds of thousands of models in a retrieval. This operation, rather than the forward model itself, is what makes the runtime drop to hours on a CPU.
What would settle it
Take a real or synthetic dataset, inject a planet signal at several levels of overlap with the telluric/systematic basis (for example, shift one strong line onto a deep telluric line, or add a stationary component to the injected signal), and run the retrieval. If the recovered mixing ratios drift away from the injected values as the overlap increases, the linear-projection assumption has failed; a clean version is to compare the recovered scale factor $\alpha$ to its injected value across the overlap grid, since the paper already finds $\alpha$ at roughly half the injected value in its fiducial tests.
Extended reading notes
Core claim
On its own terms, the paper's claim is that the distortion a detrending step (PCA, SYSREM, or NMF) imposes on a planet signal can be mimicked by a single linear projection applied to every trial forward model, and that with this operation in place a Bayesian retrieval over lines, temperatures, Doppler shifts, and scale factors is computationally cheap. Fast filtering replaces the old scheme of injecting each model into the background and refiltering it, cutting the per-model cost to a precomputable projection. The paper validates the framework with injection-recovery tests on realistic data, then re-derives the atmospheric properties of the hot Jupiter WASP-77Ab in emission and the ultra-hot Jupiter WASP-121b in transmission, finding results broadly consistent with previous published retrievals. It also reports that the retrieved signal scale factor comes out about half the injected value, that abundance posteriors shift with the choice of detrending method, and that a low-significance NH3 detection in WASP-77Ab is an artifact of the filter choice.
Load-bearing premise
The analysis assumes that applying the same linear filtering used on the data to the forward model reproduces how the real planet signal was distorted; a signal that overlaps the removed background loses part of itself to the filter, which would skew the retrieved abundances.
Editorial extensions
If this is right
- Typical emission and transmission retrievals finish in about seven hours on twenty-four CPU cores, so HRCCS abundance analyses no longer require GPUs or proprietary code.
- Reproducing the WASP-77Ab and WASP-121b results validates the method against independent analyses, which should increase confidence in, and scrutiny of, published high-resolution abundance constraints.
- Because detrending choices shift abundance posteriors, published single-method HRCCS constraints carry a systematic uncertainty that the paper's experiments bound but do not remove.
- The framework is positioned to combine high- and low-resolution data, since it reuses POSEIDON's forward models; this is the paper's stated goal for future work.
- A spurious NH3 detection in WASP-77Ab that depends on filter choice implies that chemical detections made with a single filtering method should be re-checked with at least one other method.
Reading between the lines
- A natural next step would be to treat the filter choice as a nuisance systematic, running every retrieval with two independent detrenders and quoting the spread as part of the error budget; the paper's results imply the spread can be comparable to the statistical uncertainty.
- The roughly factor-of-two deficit in the retrieved scale factor suggests a calibration diagnostic: if injection tests covering realistic signal-to-noise and telluric overlap can map how much signal each filter removes, $\alpha$ could become a correction factor for abundance estimates rather than just a nuisance parameter.
- Because the framework runs on CPUs in hours, the large archive of existing high-resolution observations could be re-analyzed at the population level, turning individual-target HRCCS retrievals into survey-scale measurements.
- Combining the fast-filtering projection with POSEIDON's existing multidimensional forward models would allow a direct test of whether 3D morning-evening or day-night structures can survive the detrending distortion; this is an implication the paper notes as future work but does not demonstrate.

Referee Report
Summary. The paper introduces a high-resolution cross-correlation spectroscopy (HRCCS) retrieval framework implemented in the open-source POSEIDON code, supporting both emission and transmission spectroscopy. It describes the forward-model modifications, detrending methods (PCA, SYSREM, NMF), a fast-filtering preprocessing step, and a Gaussian likelihood mapping that follows previous work by Brogi & Line (2019) and Gibson et al. (2020, 2022). The framework is validated with injection tests on real IGRINS and UVES data and then applied to WASP-77Ab emission and WASP-121b transmission observations, broadly reproducing previously published retrievals while documenting sensitivity to the choice of detrending filtering.
Significance. If the central claim holds, this paper makes a substantial contribution to the exoplanet high-resolution spectroscopy community by providing an open-source, CPU-only, documented retrieval framework within the widely used POSEIDON code, with runtimes an order of magnitude faster than earlier GPU-based implementations. The validation strategy—injecting known signals into real data and comparing retrievals against published WASP-77Ab and WASP-121b results—is appropriate and non-circular. The paper also explicitly demonstrates that detrending choices (PCA vs SYSREM) propagate into retrieved abundances, including a spurious NH3 detection in WASP-77Ab, which is a valuable public caveat for HRCCS abundance studies.
major comments (3)
- [4.3, Eq. (4)] The injection tests recover the scale factor alpha at roughly half its injected value. The authors attribute this to degeneracy with the retrieved P-T profile and to the filtering process, but they do not demonstrate that the attenuation introduced by the fast-filtering projection M' = U(Lambda U)^dagger (Lambda M) is a uniform scalar. If the projection removes signal in a wavelength-dependent or line-strength-dependent manner, then a single scalar alpha cannot correct for it, and retrieved abundances derived from relative line depths will be biased. The paper states that abundances are 'accurately constrained' and points to corner plots, but it does not report quantitative injection-versus-retrieval statistics (e.g., bias and scatter for each species) in the text. To support the central validation claim, the authors should provide such statistics for both emission and transmission injection tests and show that the alpha deficit is not wavelength-dependent, for example by testing recovery on wavelength subsets or comparing line ratios in the filtered models.
- [4.3] Two supporting experiments are mentioned but not shown: the authors write that 'We confirm the scaling of the signal remains unchanged after the filtering through a noiseless realization of data' and that 'we have run another experiment demonstrating the scaling can be correctly retrieved when the true profile is isothermal.' These experiments are load-bearing because they are used to argue that the alpha offset is benign and attributable to T-P degeneracy rather than to filter-induced distortion. Without presenting these results (at least in an appendix), the claim that the alpha offset does not affect abundance accuracy is unsupported. The manuscript should include the relevant figures or tables, or remove these claims.
- [5.2, Figure 9] The application to WASP-77Ab shows that retrieved chemical abundances differ by about 0.2 dex between PCA and SYSREM (e.g., log H2O is -4.33 with fixed R_p and PCA versus -4.12 with fixed R_p and SYSREM), and that NH3 is spuriously detected with SYSREM but not with PCA. The text acknowledges these user-choice differences, but the paper still concludes that 'posteriors are in agreement' with Line et al. (2021). Given the central claim is a validated framework for reliable abundance constraints, the authors should quantify the systematic spread introduced by detrending choices and explicitly state the effective abundance precision of the framework (e.g., 0.2-0.5 dex) in the summary. Without this, the reliability claim is overstated.
minor comments (6)
- [1] The acronym 'HRCSS' appears in the Introduction ('HRCSS retrieval techniques have seen limited application') and should be 'HRCCS'.
- [2.4] In the paragraph on shifting the model to the data wavelength grid, 'This is typically done by by interpolation' contains a duplicated 'by'.
- [4.3, Table 2] Section 4.3 states that the planet radius was fixed in the transmission injection test, but Table 2 lists R_r,ref as a free parameter with a Gaussian prior. Please clarify whether the radius was fixed in that test and, if so, remove it from the table or mark it as fixed.
- [6.2] The sentence 'The offset in absolute abundances can be attributed the strong correlation between each chemical abundance and cloud deck pressure' is missing a 'to' after 'attributed'.
- [7] In the first sentence of Section 7, 'transmission and emission spectrosa' should be 'spectra'.
- [5.2] The paper states 'We have no concrete evidence of SYSREM outperforming PCA in preserving planet signal' but later the same section says the stronger CO detection 'hints at SYSREM's improvement in preserving planet signals.' These statements are in tension; please rephrase to be consistent.
Circularity Check
No significant circularity: the retrieval pipeline is validated against injected signals and independent published retrievals, not derived from its own outputs.
full rationale
The paper's contribution is an open-source implementation of high-resolution cross-correlation spectroscopy retrievals, and its derivation chain does not reduce to its inputs by construction. The likelihood mapping in Section 2.5 is explicitly attributed to prior work (Brogi & Line 2019; Gibson et al. 2020), and the fast-filtering preprocessing in Section 2.4 (Eq. 4) is credited to Gibson et al. (2022); neither is presented as a new first-principles result. The central validation is against external benchmarks: injection tests with known atmospheric parameters into real datasets (Section 4), reproduction of previously published emission retrievals of WASP-77Ab (Section 5), and transmission retrievals of WASP-121b (Section 6). The self-citations to POSEIDON and Gibson et al. are to open-source code and prior methodology, and they are not load-bearing in a way that forces the conclusions. The paper candidly reports that the retrieved scale factor alpha is about half the injected value and that detrending choices change retrieved abundances, demonstrating that the framework is not engineered to return its inputs. The alpha offset and filtering-induced changes are modeling limitations, not circular reasoning, because the results are compared against independent published values and the code is publicly available for external checks.

read the original abstract
High-resolution spectroscopy (R > 25,000) has opened new opportunities to characterize exoplanet atmospheres from the ground. By resolving individual lines in planetary emission and transmission spectra, one can sensitively probe the chemical inventory and temperature structure of exoplanets. However, a significant challenge to reliable and reproducible atmospheric inferences from high-resolution datasets has been the lack of open source codes for high-resolution retrievals. Here, we present a unified high-resolution retrieval framework, for both emission and transmission spectroscopy, made publicly available within the open source POSEIDON retrieval code. Our high-resolution retrieval framework is fast (typically < 12 hours), accessible (no GPUs required), and well-documented via Python notebooks. We validate our framework by reproducing previous emission retrievals of the hot Jupiter WASP-77Ab and transmission retrievals of the ultra-hot Jupiter WASP-121b. Our results are broadly consistent with those of published works when making the same data detrending assumptions, but we demonstrate that user choices can subtly propagate into retrieved chemical abundances.
