 The removal of the unwanted signal and calibration to account for detector, optical system, or atmospheric effects in the frame counts is called Data Reduction. The result of a properly reduced frame is a science frame. It is from a science frame that most physical quantities can be estimated.\\ \\
-The removal of the detector and optical system effects is covered in [[~:..:data_reduction_telescope|Data Reduction I: Reduction to Top-of-Telescope]]. The identification and further reduction of the counts associated with sky brightness (a.k.a., light pollution) is covered in [[~:..:data_reduction_skybrightness|Data Reduction II: Removal of Sky Brightness]]. The conversion of the counts to a magnitude scale and the final step of data reduction is handled in [[~:..:data_reduction_toa|Data Reduction III: Reduction to Top-of-Atmosphere]]. The quantization of confidence in all of these measurements is discussed in [[~:..:snr|Signal-to-Noise]].
