cds-question@unistra.frgalaxiesdwarf-galaxiesvariable-starsextinctioninfrared-photometryvisible-astronomyphotometrygalaxy-radiiWe present a comprehensive catalog, in the Sloan i and Harris V filters, of long-period variable (LPV) stars in the spheroidal dwarf satellites of the Andromeda galaxy based on a dedicated survey for variable stars in Local Group dwarf systems. Using photometric time-series data obtained with the Wide Field Camera on the 2.5m Isaac Newton Telescope, we identify approximately 2800 LPV candidates across 17 Andromeda satellites, spanning a broad range in luminosity and variability amplitude. This study is accompanied by a public data release that includes two comprehensive catalogs, a catalog of the complete stellar populations for each galaxy, and a separate catalog listing all identified LPV candidates. Both are available through CDS/VizieR and provide a valuable resource for investigating quenching timescales, stellar mass distributions, and the effects of mass loss and dust production in dwarf galaxies. We derive updated structural parameters, including newly measured half-light radii, and determine distance moduli using the tip of the red giant branch method with Sobel filter edge detection, yielding values between 23.38{\pm}0.06 and 25.35{\pm}0.06mag.2026ApJ..1000...69Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/1000/69CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/183 : UBVRI Photometric Standards (Landolt 1992)I/350 : Gaia EDR3 (Gaia Collaboration, 2020)J/AJ/138/332 : LEDA CMD/tip of the red giant branch (Jacobs+, 2009)J/MNRAS/411/263 : JHK variable stars in M33 (Javadi+ 2011)J/A+A/532/A78 : Long-period variables in NGC 147 and NGC 185 (Lorenz+, 2011)J/ApJ/758/11 : Bayesian distances to M31 satellites (Conn+, 2012)J/AJ/144/4 : Dwarf galaxies in the Local Group (McConnachie+, 2012)J/MNRAS/427/343 : Infrared excesses of Hipparcos stars (McDonald+, 2012)J/ApJ/779/7 : dSph satellites of M31.
