Description:
    I magnitudes and V-I colors are given for 700 stars in a region 10'
    north of the center of the cluster NGC 6397. X and Y coordinates are
    also provided. The observations were made with the Hubble Space
    Telescope to study the luminosity distribution in a population II
    sample.
