UBVRIJKLMNH Photoelectric Photometric Catalogue

Description:
The catalog contains the results from star brightness measures in the
first ten (UBVRIJKLMN) broad wavelength bands (Johnson 1965) and the
additional bandpass H (Johnson et al. 1968). Data in the above system
that have been published up to June 1977 are included. The source
reference (Morel and Magnenat 1978) states that there are 5943 entries
in the data set with data for 4494 stars. However, a count of the
records by coded number shows that there are only 4486 unique entries
(not 4494). The catalog includes coded identification numbers (Geneva
system), 11 magnitudes, numbers of measurements in each filter, and
references.

Note on LID: (Lausanne/Geneva identifier)
The data on the magnetic tape is ordered by the coded numbers (cf.
Mermilliod J. Cl. 1978, CDS Information Bulletin, 14, 32). This
numbering scheme has the form ± C.XXXXXXXX where C has values 0 to 9
inclusive; a more recent description can be found at
http://obswww.unige.ch/gcpd/codenum.html. For reference the
following statistics were determined for this catalogue:
