VII/92A Open Cluster Data 5th Edition (Lynga 1987)
================================================================================
Catalogue of Open Cluster Data (5th Ed.)
Lynga G.
<Lund Observatory (1987)>
================================================================================
ADC_Keywords: Clusters, open ; Bibliography ; Combined data
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 :
