Description:
    This is a computer readable catalogue of open cluster data
    compiled by Gosta Lynga, Lund Observatory,
                Box 43, S-221 00 Lund, Sweden.
    The present file mainly details the structure of the file
    "catalog"; please refer to the file "intro" for more details
    about the parameters.
    Further errors have been corrected at CDS: see below the
    "Historical Notes" section. A few questions still remain
    (see section "Problems" below)
