Suppl., 34, 477 Photometry, UBVRIJKLMNH 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.

LID Coded identification number (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. For reference the following statistics were determined for this catalogue: C #Entries #Unique Entries Short Description 0 340 268 DM catalogues 1 3479 2476 HD and HDE 2 630 564 NGC clusters 3 43 34 IC clusters 4 38 38 Anonymous clusters (< 100) 5 563 407 Anonymous clusters ( >100) 6 394 338 Catalogues and lists of stars 7 0 0 Selected area stars 8 72 61 Catalogues ordered by declination zones 9 384 300 Stellar associations and nearby galaxies Totals 5943 4486 --- n_LID Suffix to LID Symbol Entries Significance D 231 Unresolved binary 1 21 Component A of a double star 2 19 Component B of a double star 3 4 Component C of a multiple star system S 0 Supplementary star in a list, possessing the same identification as another one, followed by "a" or "s".
