DEC: -20 EXPOSURE JD: Mid-exposure JD CORR METHOD: Light-time JD CORRECTION: JD = JD(raw) - 0.01577d UNITY CORR: -5 * log(SunDist * EarthDist): -4.9282 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.

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) ********************************************************************************************* TARGET: 36 Atalante SESSION NUMBER: 515 DATE/TIME: 2008 May 24 @ 10:00 FILTER: C TELESCOPE: 0.35m SCT FOCAL LENGTH: 77.00 CAMERA: SBIG ST-8E TEMP (C): -15 EXPOSURE (s): 240 APPROX.
