Catalogue of Open Cluster Data (5th Ed.) LYNGA G.: 1987 <Lund Observatory>
ADC_Keywords: Clusters, open ; Bibliography ; Combined data 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) File Summary:

Note (3): the survey may be SO, O, E, J, R, I or SR Note (4): the "C" cluster designation has the general "format" CHHMM+DDd, i.e. starts with the letter 'C', followed by the right ascension (1950) in hours and minutes. followed by the declination sign, degree and tenth of degree. Note (5): this field is apparently in error, it contains frequently "-1" or "**"Note (6): w_RVel has only the values 0.0 or 1.0 Note (6): w_RVel has only the values 0.0 or 1.0 Note (7): the unexplained reference (-1) exists for the clusters C0728-168, C0728-169, C1726-324 Note (8): tracers are indexes of the previous or next entry according to the parameter; it has been omitted for C2357+606

It is the only one from ref. 378 (Pfleiderer et al., 1977) * The positions disagreed with galactic position and have been corrected for the following clusters : ------------------------------------------------ Cname Original Position from galactic pos. 1950 (1950) (2000) ------------------------------------------------ C0819-360 820.3-3614 0819.2-3601 0821.1-3611 C0820-360 821.5-3610 0820.2-3559 0822.1-3609 C0915-495 914.1-4947 0915.0-4930 0916.7-4943 C1654-457 1654.3-4551 1654.2-4543 1657.9-4548 ------------------------------------------------
