Lines: 16 A short time ago someone posted an abbreviated version of the Yale Catalog of Stars. I'm enthusiastic about playing with the data, but I don't understand one of the fields; the description is: ***** Color ***** Sign A1 B-V in UBV System I3 (unit = 0.01 magnitude) Can anyone fill me in on what measure of color this is?
