This is more specific than a generic worry about reference selection or missing uncertainties: it is an actual error in the data product that is recommended for calibration. The concern is fixable by regenerating the tables from the primary sources and, ideally, providing machine-readable files with uncertainties.

The same row also violates expected monotonicity of the n=3, 4, and 5 series members. Thus at least one row of the calibration table is corrupted, and without a systematic check against the source papers other rows may contain similar misplaced or mistyped entries.

The stated purpose is to provide a practical resource for plasma diagnostics and energy-scale calibration, with the authors asserting that the H-, He-, and Li-like transition energies in Tables 1–3 are state-of-the-art calculations currently considered the best available.

Tables 1 and 2 are the reason to use this paper, and Table 1 has at least one corrupted row, so it cannot serve as a calibration resource as printed. The underlying idea is sound, the source list is solid, and the paper is honest about what it is. But the main selling point—state-of-the-art transition energies ready for energy-scale calibration—is undercut by transcription errors and missing uncertainties.\n\nWhat is actually new: not much scientifically. The paper compiles published CODATA constants, Yerokhin et al., Erickson, Holzer, and others, and reformats them into convenient tables. It also gives parameterized Lorentzian models for neutral fluorescence lines, including some refits (Mn K-alpha) and one hand-adjusted Rb width. That is incremental, but a well-curated collection is genuinely useful to the X-ray spectroscopy community, especially for XRISM/Resolve calibration work.\n\nCredit where due: the authors are explicit that this is a resource, not a new result. They list sources with DOIs and ADS links and include caveats about source-dependent line shapes and the lower accuracy of neutral data. That is the right framing, and the citation pattern looks clean—the values come from independent published calculations.\n\nSoft spots: the load-bearing problem is Table 1. In the Ni row, Ly-beta-2 is printed as 11973.2173 eV and Ly-gamma-1 as 11444.2486 eV, while the series limit is 10775.3948 eV. A bound transition cannot exceed the ionization limit, and n=4 cannot lie above n=3. The K row also has Ly-beta-1 below Ly-beta-2, which is the wrong ordering. These are not judgment calls; they are transcription errors. Since the table's stated purpose is direct use for calibration, even a single such error means the table as printed fails that purpose. The whole table needs systematic checking against the source papers before anyone uses it. I also note that the calibration tables carry no uncertainties, which is a strange omission for a document aimed at calibrating high-resolution instruments. Table 4's hand-adjusted Rb width is flagged, which is honest, but it is still an undocumented tweak.\n\nWho this is for: working X-ray spectroscopists and instrument teams who need a quick entry point to the literature. They will get value from the reference list and the neutral-line-shape models, but only after the errors are fixed and a machine-readable version with uncertainties is provided.\n\nI would send this to peer review with a request for heavy revision—specifically, recompute or re-transcribe every table entry, add uncertainties, and state the verification procedure. A corrected version deserves to be in the literature.","headline":"Useful reference compilation undermined by corrupted Table 1 entries; needs correction before calibration use.","tokens_in":55012,"tokens_out":2524,"would_cite":false,"duration_ms":26877,"reading_group":"maybe","serious_thinker":"yes","would_accept_peer_review":true},"rs_alignment":null,"lean_confirmation":null,"pith_extraction":{"msc":[],"pacs":[],"model":"deepseek-v4-flash","headline":"This paper curates reference atomic data for X-ray K-shell lines and presents four tables that it offers as best-available energies and line shapes for calibration and diagnostics.","keywords":["X-ray spectroscopy","atomic transition energies","K-shell transitions","H-like ions","He-like ions","Li-like ions","fluorescence line shapes","energy calibration"],"falsifier":"Inspect the Ni Ly$\\beta_2$ entry in Table 1: the printed value 11973.2173 eV is larger than the adjacent Ly$\\gamma_1$ value 11444.2486 eV and far above the same row's Ly$\\beta_1$ value 9586.0644 eV; recomputing that transition from Erickson (1977) with the Yerokhin and Shabaev (2015) ground state will show whether the entry is a transcription error and whether the table can be trusted for calibration.","tokens_in":53959,"feed_emoji":"⚛️","tokens_out":8276,"duration_ms":75109,"temperature":0.7,"pith_summary":"This paper argues that a small set of curated atomic-physics references, condensed into four quick-look tables, gives the community ready-to-use values for the K-shell lines most often used in X-ray spectroscopy: transition energies for H-, He-, and Li-like ions, and line positions and shapes for neutral fluorescence lines. The authors intend these tables to serve as a first-stop resource for plasma diagnostics and, in particular, for energy-scale calibration of high-resolution spectrometers, since the H- and He-like energies come from what they consider the best available calculations. If the tables are accurate, a user can adopt the printed values directly, with citation to the original calculations, rather than re-deriving or hunting through the literature. The document also supplies constants, unit-conversion conventions, branching-ratio references, and notation conventions that make the tables self-consistent.","feed_headline":"Four tables give best-available X-ray line energies for calibration","feed_subtitle":"Curated K-shell energies for H-, He-, and Li-like ions plus neutral fluorescence shapes, ready for high-resolution spectrometers.","key_machinery":"The carrying objects are the four quick-look tables.

The tables are tied to specific source references and, for the neutrals, to empirical solid-target measurements.

Table 4 provides empirical multi-Lorentzian models for neutral K-alpha and K-beta line shapes, based on very high-resolution laboratory measurements of solid targets, and the paper states that this neutral table is consistent with the reference used for the energy-gain scale calibration of the XRISM/Resolve instrument.
