I call the AAVSO API to get me the VS data and the candidate comparison stars in a requested mag. range and chart width. I use the B-V from SIMBAD to give me a guide to any major differences that there might be in the B-V values of the comparison stars. It’s more of a sanity check

So there is a Sanity Clause after all!
