Why do some get prim/second/ter/iaryBand entries (just curious)? Is it worth mentioning something about how the constant values are determined?

The formulae are in the appendix of the FGCM Burke et al paper, and the constants ... well, I should put my scripts somewhere, but they come from eyeballing synthetic loci actually. Things are not super sensitive to these constants (at least in any metrics that we looked at in DES)
