J-K= 1.82. ASAS-3 magnitudes contaminated by the red star 2MASS J18115659-1852234 which might also be variable (V= 13.6 derived from UCAC3 and CMC14 but V= 14.2 derived from APASS r'; J-K= 1.46 sep. 21") and also by CMC14 J181157.7-185204 (V= 16.1:; sep. 8.6") and UCAC4 356-126455 (V= 15.8; sep. 17"). Range has been corrected. |
