Data was only determined for two comp stars, and the target star, eclipsing binary V474 CAM.  The first comp star has B-V = 0.21 and the second comp star has B-V = 0.43.  There were significant airmass variations over the course of the measurement run as the astronomer was trying to collect the entire light curve in one evening and, to do this, had to allow the target well below 30 degrees elevation.
