  where:

    r_std is the standard, or calibrated, magnitude of the star
10 3 Douglas Tucker
    (g-r)_std is the standard, or calibrated, g-r color of the star
11 3 Douglas Tucker
    a_r is the photometric zeropoint in r
12 3 Douglas Tucker
    k_r is the first-order extinction in r
13 3 Douglas Tucker
    b_r is the instrumental color term coefficient in r
14 3 Douglas Tucker
    X is the airmass
15 3 Douglas Tucker
    0.53 is a "fiducial" reference color for stars in g-r (based on SDSS experience)
16 3 Douglas Tucker
17 3 Douglas Tucker
    Note that there is a separate photometric zeropoint (a_r) and

    instrumental color term coefficient (b_r) for each CCD.
