TARGET: 426 Hippo SESSION NUMBER: 433 DATE/TIME: 2008 Apr 01 @ 09:00 FILTER: C TELESCOPE: 0.35 FOCAL LENGTH: 77.00 CAMERA: SBIG ST-8E TEMP (C): -15 EXPOSURE (s): 30 APPROX. RA: 10:04 APPROX. DEC: - 7 EXPOSURE JD: Mid-exposure JD CORR METHOD: Light-time JD CORRECTION: JD = JD(raw) - 0.01005d UNITY CORR: -5 * log(SunDist * EarthDist): -3.2671 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: -8.567 BASE CORRECTION: +0.000 PHASE/DIST CORR: +0.000 P/D ADJUST (-/DAY):+0.020 P/D ADJUST (+/DAY):-0.020 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) ********************************************************************************************* ------------------------------------------- J.D.
