It's a minor thing, but since the filters, in order, are UBVRI it seems like the table columns should be ordered U-B, B-V, V-R, and R-I instead of the current ordering which is B-V, U-B, V-R, and R-I. I want to change it, but there may be a convention I'm unaware of that lists them in this order. So I'll leave it for now pending any responses to this and if no one has any objections I'll come back later and reorder it.
B-V is the most widely used best temperature calibrated index. Index UB may be not present in the measured index set, but BV will (almost) always be present. Interstellar extinction is usually expressed as color excess E(BV) or is frequently normalized to that excess. Orionus (talk) 19:48, 15 April 2016 (UTC)
