Since we're now restricting the color range of sources used in photoCal,
|
the color terms have changed slightly. These values were calculated by
|
Masayuki Tanaka, supplied in e-mail ([Hsc_software 6029] Re: color terms).

I can confirm that the numbers match those provided by Masayuki Tanaka. You may want to note in the commit message (as he did in e-mail [Hsc_software 6029] Re: color terms) that "These are from the Pickles library, but the numbers from BPGS [Bruzual-Persson-Gunn-Stryker library] are similar."
Thanks Lauren.
Updated the commit message and merged to master.
