				<para>
    The catalog is a compilation of photoelectric photometry obtained as
    part of a program investigating the distribution of stars and stellar
    matter perpendicular to the galactic plane. Compared to the
    publication, the "catalog" file does not include the position, the
    spectral type, the source of the UBV photometry, and neither the
    number of measurements in the narrow-band filters.</para><para>    The narrow-band filters are:
    -----------------------------------------------
    m(4508)   centered at 450.8nm, half-width=5.0nm
    m(4269)   centered at 426.9nm, half-width=4.3nm
    m(4176)   centered at 417.6nm, half-width=4.0nm
    -----------------------------------------------
    ge = m(4269) - m(4508) measures the break at the G-band
    ce = m(4176) - m(4269) measures the CN absorption.</para></description>
