TARGET: WASP103b SESSION NUMBER: 220 DATE/TIME: 2020 Jul 28 @ 23:00 FILTER: C TELESCOPE: 0.35cm f/5 SCT FOCAL LENGTH: 69.00 CAMERA: ST7-XME TEMP (C): 0 EXPOSURE (s): 300 APPROX. RA: 00:00 APPROX. DEC: +00 EXPOSURE JD: Mid-exposure JD CORR METHOD: Light-time JD CORRECTION: JD = JD(raw) - 0.00000d UNITY CORR: -5 * log(SunDist * EarthDist): N/A (Sun and/or Earth distance not computed) 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. BASE COMP VALUE: +0.000 BASE CORRECTION: +0.000 PHASE/DIST CORR: +0.000 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.
