1 Prokopovich, Andrey Identification is uncertain. ASAS-3 and NSVS data are for a blend of 4 stars. Two close binaries 20" apart. The star identified as the variable has a 17.4 V-mag. companion 3".9 away (SDSS J042536.16+072853.6). The other close binary is made up of a 15.7 V-mag. star (2MASS J04253502+0728587) and a 16.6 V-mag. star (2MASS J04253508+0729035) 4".6 away. The range of the blend is V= 13.65 - 14.1. The range given in the table has been corrected from light contamination by the other 3 stars. 2MASS J04253502+0728587 could also be the RR Lyrae star, although the possibility is unlikely because then the amplitude would be larger than normal, V= 14.7 - <16.
