This paper presents a conceptual introduction to the Lomb-Scargle periodogram and important practical considerations for its use. Rather than a rigorous mathematical treatment, the goal of this paper is to build intuition about what assumptions are implicit in the use of the Lomb-Scargle periodogram and related estimators of periodicity, so as to motivate important practical considerations required in its proper application and interpretation.","external_url":"https://arxiv.org/abs/1703.09824","cited_by_count":1020,"metadata_source":"pith","metadata_fetched_at":"2026-06-27T08:30:44.782646+00:00","pith_arxiv_id":"1703.09824","created_at":"2026-05-08T18:33:57.845161+00:00","updated_at":"2026-06-27T08:30:44.782646+00:00","title_quality_ok":true,"display_title":"VanderPlas , title =","render_title":"VanderPlas , title ="},"hub":{"state":{"work_id":"8fd7d62e-8118-47c3-829f-380ec23eedec","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":23,"external_cited_by_count":1020,"distinct_field_count":5,"first_pith_cited_at":"2024-05-20T18:47:25+00:00","last_pith_cited_at":"2026-06-24T22:10:59+00:00","author_build_status":"not_needed","summary_status":"needed","contexts_status":"needed","graph_status":"needed","ask_index_status":"not_needed","reader_status":"not_needed","recognition_status":"not_needed","updated_at":"2026-06-27T11:05:58.264163+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"method","n":4},{"context_role":"background","n":3}],"polarity_counts":[{"context_polarity":"use_method","n":4},{"context_polarity":"background","n":3}],"runs":{},"summary":{},"graph":{},"authors":[]}}
