I collected some (B, V) images last night for V0512 Cam which is near the north celestial pole. When trying to analyze them today I found that none of the sequence stars have B values. I generally transform my observations but this means I can’t do that, nor can I even get untransformed B values.
I’ve never run into this before. All of the comp stars are listed as coming from Gaia DR2. Looking at the past data collected for this star, people are reporting B values so at some point the comp stars must have had this.
Is there any way to proceeded?
