- Description:
- The fifth edition of the Lund Catalogue of Open Cluster Data gives key
- information for all known open star clusters in this galaxy. As far as
- possible only published data have been quoted; for some of the
- parameters, these values have been selected from other references, which
- are listed. The catalog includes cluster identification, position,
- reference, Trumpler classification, membership, angular diameter, mean
- distance, reddening, turn-off color, age, Fe/H, radial velocity, star
- types, magnitudes, color, number of observed stars, richness class,
- earliest spectral class, magnitude brightest member, galactocentric
- distance, linear diameter, and comments.
- Further errors have been corrected at CDS: see below the
- "Historical Notes" section. A few questions still remain
- (see section "Problems" below)

- Note (2): this field is always blank.
- Note (3): the survey may be SO, O, E, J, R, I or SR
- Note on Cname (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 (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

- Historical Notes:
- * Oct-1991: ADC CD-ROM "Selected Astronomical Catalogs" Vol. 1
- (directory /nonstell/clusters/open) : see file "intro.doc"
- * 14-Feb-1995: CDS (Francois Ochsenbein)
- => file "edited":
- - removed the duplicated last two clusters C2351+614 and C2353+642
- - corrected the (erroneously positive) declinations of
- C0635-008 C1859-005 C0657-001 C0719-008
- => file "catalog":
- - transformed into a file with 514-byte records;
- - replaced blank values of 'N(UGem)' with zero;
- - put sign of declinations in constant column
- - removed first record with initial tracers
- - corrected misalignments for C0548+217
- - corrected declinations for C0717-010,
- C0635-008 C1859-005 C0657-001 C0719-008
- - corrected positions of C0819-360, C0820-360, C0915-495
- and C1654-457 (see below)
- - added C2357+606 (Berkeley 58, 1st record) which was missing
- (existed in "edited", but not in "catalog")
-
- Problems:
- * Cluster "C2306+606" indicates an unknown '64' ClSeq with '1'
- number in file "catalog" and blank name in file "edited".
- 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)
