... This pap er describ es distortion calibration procedures for the SOHO /LASCO-C2 Coronagraph, based on in-orbit data and extensive image processing methods. ... C2 suffers from moderate optical distortion, which must b e corrected in order to prop erly locate the stars crossing its field-of-view (which are subsequently used for photometric calibrations), to retrieve critical attitude parameters, and to insure a correct overlapping of the region common to the C2 and C3 instruments. ...

... The way of forming its resp onse is rather sp ecific, so various programs to process its data were required. ... A set of IDL programs was develop ed which allows us to look through the records and view data in various representations; to measure a radio source size, flux, and its location on the Sun; to build high-sensitivity 1-D images, etc. ... After appropriate preprocessing, these images could b e imp orted into a program to b e viewed together with the SSRT data. ...

... The algorithm, known as Variable-Pixel Linear Reconstruction (or informally as "drizzling"), preserves photometry and resolution, can weight input images according to the statistical significance of each pixel, and removes the effects of geometric distortion b oth on image shap e and photometry. ... In the drizzling algorithm, no compromises on signal-to-noise have b een made, and the weight of an input pixel in the final output image is entirely indep endent of its p osition on the chip. ...
