Abstract:
    Photoelectric data on the Johnson-Kron-Cousins UBVRI broadband
    photometric system are provided for a set of stars that have been used
    as spectrophotometric standard stars for the Hubble Space Telescope.

Description:
    The Kitt Peak National Observatory (KPNO) 1.3m telescope was
    scheduled for this program for 101 nights in the interval of 1985
    September to 1991 June.
