cds-question@unistra.frvariable-starshst-photometryA search for variable stars is performed using two epochs of Hubble Space Telescope Advanced Camera for Surveys imaging data for a 9.28arcmin^2^ portion of M31. This data set reveals 254 sources that vary by at least 4{sigma} between epochs. The positions and two-epoch B-band (equivalent) photometry of these sources are presented.2005AJ....129.2663Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/129/2663CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/402/113 : (RI)c photometry of variables in M31 (Joshi+, 2003)J/A+A/421/509 : AGAPE catalogue of M31 variables (Ansari+, 2004)J/ApJS/154/623 : M31 Long Period Variables : Photometry (Mould+, 2004)J/MNRAS/351/1071 : POINT-AGAPE Survey.
