Description:
    Deep CCD photometry has been performed in four CCD frames inside
    Kapteyn's special Selected Area 53, which is known as a low extinction
    Window of the Galactic Anticenter. The catalogues of stellar objects
    detected in 4 CCD fields brighter than V = 25 are given in the file
    "fields", merged from original fields 1, 2, 3 and 4.
