Preparing multiple CCD frames for the photometry of extended fields.
Abstract
The author presents methods for the automatic determination of the global offsets between arbitrary amounts of imaging data, by image feature detection and the conversion of these positions to labelled lists. He also discusses a method that allows the propagation of errors through robust estimation (median, trimmed mean) operations, allowing the true intrinsic errors to be maintained through the initial processes of CCD data reduction.
