    r_std is the standard, or calibrated, magnitude of the star
10 1 Douglas Tucker
    (g-r)_std is the standard, or calibrated, g-r color of the star
11 1 Douglas Tucker
    a_g is the photometric zeropoint in g
12 1 Douglas Tucker
    k_g is the first-order extinction in g
13 1 Douglas Tucker
    b_g is the instrumental color term coefficient in g
14 1 Douglas Tucker
    X is the airmass
15 1 Douglas Tucker
    0.53 is a "fiducial" reference color for stars in g-r (based on SDSS experience)

    Note that there is a separate photometric zeropoint (a_i) and
