1 Ferrante, Farley ROTSE-I magnitudes are for the blend of GSC 03013-02439 (V= ~13.7, B-V= 0.74; J-K= 0.44), identified as the variable star, and GSC 03013-00333 (V= 14.3, B-V= 0.82; J-K= 0.50) which is 51" to its NE. Identification is based on the magnitudes derived from APASS, SDSS, UCAC3 and CMC15 which show a wider spread for the brighter star, especially the large standard deviation found from two measures in the CMC15 catalogue (0.11 for the brighter star and 0.01 for the fainter one). The range given in the table is for the combined brightness of the two. The amplitude of the variations should be 0.25 instead of 0.15 mag. if the star is correctly identified.
