		| Abstract: | 
		This paper describes distortion calibration procedures for the SOHO/LASCO-C2 Coronagraph, based on in-orbit data and extensive image processing methods. It addresses specific problems of externally occulted coronagraphs (obstructed center of field-of-view, strong vignetting, and presence of stray light) and limitations inherent to space-based instrumentation (cosmic rays and limited number of reference points). |
