NSVS light curve is for the blend of KW Vul with 2MASS J20210556+2759584 (V= 15.4; J-K= 1.63; sep. 4") and GSC 02163-01576 (V=
12.34; J-K= 0.46; sep. 25"). The companion 4" away is identified as the variable in IBVS 4789 but UCAC3 and CMC14 data show that the variable object is 2MASS J20210529+2759598 (J-K= 1.19) with derived V= 14.0 (UCAC3) and V= 15.6 (CMC14). |
