The Data for Correction of Star Catalog Positional and Proper Motion Systematic Errors for Natural Satellite Astrometry
Zhe Yang ; Huiyan Zhang ; Kai Tang ; Yong Yu ; Shilong Liao ; Dan Yan ; Rongchuan Qiao
Spatially resolved position and proper motion corrections for 17 historical star catalogs (AC, ACRS, ACT, AGK1, AGK3, FK4, Gaia DR1/DR2, GSC1.2, Hipparcos, PPM, SAO, Tycho-2, UCAC2/4, USNO-A2.0, Yale), derived by cross-matching against Gaia DR3 on a HEALPix sky grid (N_side = 64 and 256). Corrections include Δα·cosδ, Δδ (position) and proper motion offsets in RA/Dec, all referenced to epoch J2000.0. Intended for reprocessing natural satellite astrometric observations to remove spatially correlated systematic biases.
