NOTE:            For multiple sessions, differential magnitudes include
                 adjustments ADDED to the Obj-CAvg value to compensate
                 for changing phase angle, distance, and refinements to
                 the base average value of the comparison stars.
BASE COMP VALUE: +13.244
BASE CORRECTION: +0.000
PHASE/DIST CORR: +0.000
 
ERROR CALC:      The magnitude error is calculated by the following:
                 Err = sqrt(sqr(ERR[target]) + sqr(Err[Comps]))
                       where Err[Target] = 1.0857/SNR[target]
                             Err[Comps]  = sqrt(sqr(1.0857/SNR[Comp1])... + sqr(1.0857/SNR[CompN])) / N
                 The factor of 1.0857 converts flux to magnitudes (Howell)
