TARGET: 134340 Pluto SESSION NUMBER: 1879 DATE/TIME: 2007 Mar 18 @ 11:00 FILTER: C TELESCOPE: 0.35m f/9.1 SCT FOCAL LENGTH: 129.00 CAMERA: SBIG STL-1001E TEMP (C): -30 EXPOSURE (s): 10 APPROX. RA: 17:55 APPROX. DEC: -16 EXPOSURE JD: Mid-exposure JD CORR METHOD: Light-time JD CORRECTION: JD = JD(raw) - 0.18047d UNITY CORR: -5 * log(SunDist * EarthDist): -14.9500 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: -10.972 BASE CORRECTION: +0.000 PHASE/DIST CORR: +0.000 P/D ADJUST (-/DAY):-0.001 P/D ADJUST (+/DAY):+0.001 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.
