TARGET: 2754 SESSION NUMBER: 102 DATE/TIME: 2006 Sep 04 @ 10:00 FILTER: C TELESCOPE: 0.36m SCT FOCAL LENGTH: 57.14 CAMERA: SBIG ST-8E Bin1 TEMP (C): -15 EXPOSURE (s): 240 APPROX. RA: 23:38 APPROX. DEC: +11 EXPOSURE JD: Mid-exposure JD CORR METHOD: Light-time JD CORRECTION: JD = JD(raw) - 0.00432d UNITY CORR: -5 * log(SunDist * EarthDist): -0.5535 NOTE: The unity correction is NOT included in the reduced magnitudes. MAG. METHOD: M/IR Derived 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: +12.995 BASE CORRECTION: +0.000 PHASE/DIST CORR: +0.000 P/D ADJUST (-/DAY):-0.027 P/D ADJUST (+/DAY):+0.027 THE P/D ADJUSTMENTS ARE NOT 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) ********************************************************************************************* ------------------------------------------- J.D.
