TARGET:          4483 Petofi

SESSION NUMBER:  76

DATE/TIME:       2007 Jul 16 @ 07:32

FILTER:          C

TELESCOPE:       300 mm f11.5 cass

FOCAL LENGTH:    136.43

CAMERA:          AltaU6 1x bin

TEMP (C):        -30

EXPOSURE (s):    180

APPROX. RA:      16:47

APPROX. DEC:     +23

EXPOSURE JD:     Mid-exposure

JD CORR METHOD:  Light-time

JD CORRECTION:   JD = JD(raw) - 0.00708d

UNITY CORR:      -5 * log(SunDist * EarthDist): -1.8754

NOTE: The unity correction is NOT included in the reduced magnitudes.

MAG. METHOD:     Instrumental

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.       

                 The phase angle calculations include the effects of   

                 the phase parameter, G. This value is taken from the  

                 MPCORB value at the time the calculations were made.

BASE COMP VALUE: -7.477

BASE CORRECTION: +0.000

PHASE/DIST CORR: +0.000

P/D ADJUST (-/DAY):+0.011

P/D ADJUST (+/DAY):-0.011

THE P/D ADJUSTMENTS ARE INCLUDED IN THE VALUES BELOW.

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)
