TARGET:          1664 Felix
SESSION NUMBER:  398
DATE/TIME:       2008 Mar 17 @ 12:00
FILTER:          C
TELESCOPE:       0.35
FOCAL LENGTH:    77.00
CAMERA:          SBIG ST-8E
TEMP (C):         -5
EXPOSURE (s):    120
APPROX. RA:      15:38
APPROX. DEC:     -17
EXPOSURE JD:     Mid-exposure
JD CORR METHOD:  Light-time
JD CORRECTION:   JD = JD(raw) - 0.00746d
UNITY CORR:      -5 * log(SunDist * EarthDist): -2.0631
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: -7.819
BASE CORRECTION: +0.000
PHASE/DIST CORR: +0.000
P/D ADJUST (-/DAY):-0.019
P/D ADJUST (+/DAY):+0.019
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)
