RFS-X Earth-Side Field-State Hourly Dataset: 2025 August–September 19-Day Type IV Solar Radio Burst Window

Hourly Earth-side field-state classification records for the 2025 August–September 19-day Type IV solar radio burst window (Krupar et al. 2026, ApJL 1003:L5), produced by the RFS-X field-state monitoring system. This deposit contains four files: rfsx-events-v1-2025-08-01_2025-09-30.csv: External event catalog for the window (CME arrivals, geomagnetic storms, IceCube neutrino events, GRB events) rfsx-historical-v1-2025-08-01_2025-09-30.csv: Hourly RFS scalar and dM (momentum sub-component) records for the same window rfsx-research-cps-events-v1-2025-08-17_2025-09-13.csv: Hourly CPS (Coherent Pattern System) classification records (533 hourly records, Aug 17–Sep 13, 2025) Lanum2026_CPS_DataNote_TypeIV_v1.1.pdf: Companion data note reporting analysis of the CPS classification records against the solar-side timeline documented by Krupar et al. (2026) The CPS dataset is analyzed in the companion data note included in this deposit. The RFS scalar and dM records support the field-state arc described in the companion Comment paper (Lanum 2026, Comment on Krupar et al. 2026).
