[vsnet-chat 536] Re: Red variables and high B-V values

[bas@lowell.Lowell.Edu (Brian Skiff)]

     Masi's CCD frames were both unfiltered images, so any changes in
spectral sensitivity mimicking variability would be minimal.  The A1.0
catalogue was generated (in the north) from the original POSS-I blue and
red plates, which were taken back-to-back, so the color is a real effect.
