# IBVS 3224-t1.txt #Object: RZ Cas #Author: D.V. Arganbright, W. Osborn, D.S. Hall #IBVSdataKey: photometry #Comment: same data as IAU C27 UNPUBLISHED DATA FILE No. 156 #Source: W. Osborn # Instrumental V and B differential magnitudes for # RZ Cas # # H.J.D. = Heliocentric Julian date of the observation # (usually the middle of a sequence of V-B-sky-B-V measurements) # # Delta V = differential V magnitude of RZ Cas relative to # HD 15784 # # Delta B = differential B magnitude of RZ Cas relative to # HD 15784 # # D(B-V) = Delta B mimus the corresponding Delta V # # # Notes on the observations: Data were taken on seven nights # but the results are given for only four. For the other # three nights, one was used to determine the approximate # magnitude and color of the comparison star HD 15784 # (measured as V = 6.56, B-V = 0.41), one was used to test # the constancy of the comparison star by a series of # differential measures relative to a check star (HD 15794 # was found constant to 0.02 mag), and on one night clouds # stopped observations after just a few measures well # outside of eclipse.
