TARGET: 1717 Arlon SESSION NUMBER: 771 DATE/TIME: 2010/05/18 @ 07:00 OBSERVER: J. Q. Astronomer CONTACT INFO: J. Q. Astronomer, 123 Main St., Anytown, CO, USA [youremail@adomain.com] FILTER: C TELESCOPE: Meade 14" LX200GPS FOCAL LENGTH: 1420.00 CAMERA: SBIG ST-8E TEMP (C): -15 EXPOSURE (s): 240 APPROX. RA: 16:06 APPROX. DEC: -31 EXPOSURE JD: Mid-exposure JD CORR METHOD: Light-time JD CORRECTION: JD = JD(raw) - 0.00820d UNITY CORR: -5 * log(SunDist * EarthDist): -2.6785 NOTE: The unity correction is NOT included in the output 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: -9.173 BASE CORRECTION: +0.000 PHASE/DIST CORR: +0.000 PHASE SLOPE: 0.15 P/D ADJUST (-/DAY):-0.017 P/D ADJUST (+/DAY):+0.017 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) Comp1: 140039.63 -104329.1 0.000 0.000 V Y Comp2: 140053.95 -104614.0 0.000 0.000 V Y Comp3: 140023.26 -104533.2 0.000 0.000 V Y Comp4: 140054.60 -104107.2 0.000 0.000 V Y Comp5: 140035.83 -103909.5 0.000 0.000 V Y ********************************************************************************************* J.D.
