MJD56241-i¶

Form of the Photometric Equation¶

  i_std = -2.5log10(counts[ADU]/sec) - a_i - k_i*X - b_i*( (i-z)_std - 0.09) )

  where:
    i_std is the standard, or calibrated, magnitude of the star
    (i-z)_std is the standard, or calibrated, i-z color of the star
    a_i is the photometric zeropoint in i
    k_i is the first-order extinction in i
    b_i is the instrumental color term coefficient in i
    X is the airmass
    0.09 is a "fiducial" reference color for stars in i-z (based on SDSS experience)

    Note that there is a separate photometric zeropoint (a_i) and 
    instrumental color term coefficient (b_i) for each CCD.
