    "A computer readable catalog of constellation boundary data is",
    "presented in a form suitable for the construction of star charts and",
    "atlases. Two data files are available, one for equator and equinox",
    "1875 and the other for equator and equinox 2000. In addition to the",
    "data files a documentation file is available that includes a table",
    "listing the abbreviations used for the constellations as well as a",
    "more detailed discussion of the preparation of the catalog.",
    "",
    "The present catalog of constellation boundary data is complementary to",
    "that of Roman (1987). Roman's catalog should be used to determine in",
    "which constellation an object lies in. The present catalog is more",
    "suited to the construction of star charts and atlases. Both catalogs",
    "were based on Delporte (1930)."

Pickup for useful discussions about the format of Delporte's lists and the effect of precession on the shape of the constellation boundaries and to Dr. W.H. Warren Jr. for several useful suggestions. This work was carried out as part of a contract with the Edinburgh publishers John Bartholomew and Son Ltd. to provide data for a revised edition of `Norton's Star Atlas'.",
