Recognition of objects and position recovery from microdensitometer measurements of large field plates The Coma region on a glass copy of the Palomar Sky Survey has beenscanned with a microdensitometer. A method is described for obtainingthe photometric parameters and positions of the images; 12,316 objectshave been found. The repositioning of the scanner over the computedcoordinates is satisfactory. AGK3 stars were considered to evaluate theplate constants and the precision. Comparison with Dressel and Condon's(1976) positions of galaxies gives a rms scatter consistent with theinternal error of the published list.
