Photometric Data Sets Summarized in Tables 1, 4, 7, and 10
These eight data files contain the Johnson BV differential magnitudes of Lambda And, Sigma Gem, II Peg, and V711 Tau summarized in Tables 1, 4, 7, and 10 of the paper in the sense variable minus comparison. The first column of each file gives the heliocentric Julian Dates (HJD - 2,450,000) and decimal. The second column gives the differential magnitudes.
