I have a transformed set of filters and have just started running tests and submissions. Most of the values that I'm finding are right in line with the light curves (B and V values).
But, some are way off. Is there a guide or documentation anywhere discussing why a given observation would be abnormal? As an example, I was just working with zet Gem. There is a fairly wide spread between B and V values. But in my measurement the B and V are close together and much brighter than the other observations. Mine are obviously wrong, but how does one figure out what went wrong. My first inclination is to take another set and see if I get the same wrong results.
I don't have an answer, but questions.
Looking at Zeta Gem data in LCG, I note that R and especially I data is much brighter than V and B. Could one of both of your filters have an IR "leak", resulting in brighter B and V than expected??
Which filters do you use?? I can't evaluate, but other smart people here may have answers or at least opinions.

I'm sure everyone at some stage ends up with observations that are clearly incorrect. It's happened to me.
All I can suggest (because this is what I do) is to go back over the procedures involved and simply check all of them in the order in which they were carried out. If you set up calculations yourself, check the formulae, the inputs and the outputs. If something is clearly wrong, you may well find a specific reason for it.
