dc.descriptionWe describe in detail the processing of a set of images of the z = 0.42 supercluster MS0302 taken with the UH8K camera at CFHT. The result of this is a pair of seamless combined V- and I-band images of the field, along with a characterization of the noise properties and of the point spread function (PSF), and catalogs of about 30,000 faint galaxies. The analysis involves the following steps: image preparation; detection of stars and registration to find the transformation from detector to sky coordinates; correction for extinction and/or gain variations; modeling of the PSF; generation of images with a circular PSF; image warping and averaging; modeling of the noise auto-correlation function; faint object detection, aperture photometry, and shape measurement. The shear analysis is described elsewhere.
