Abstract:
We determine the integrated magnitudes and colours of 650 clusters in
optical (BV) and the near-infrared (JHKs) passbands and construct the
luminosity functions of the Galactic open clusters in these passbands.
Description:
The catalogue presents integrated parameters in optical (BV) and
near-infrared (JHKs) passbands for 650 Galactic open clusters. The
integral magnitudes are based on the most probable cluster members
selected from the high-precision, homogeneous all-sky catalogue
ASCC-2.5 (Kharchenko, 2001, Cat. I/280). The integrated magnitudes
are computed by adding the individual luminosities of the most secure
cluster members. In order to put the computed magnitudes into a
uniform and unbiased system they were corrected for the effect of
unseen stars in the ASCC-2.5. The clusters in the catalogue are sorted
according to their order in the COCD.
The file tablelf.dat presents cluster luminosity functions (CLF) in
five BVJHK_s photometric passbands for three cluster samples which
differ by the upper limit of age of the included clusters: logt≤9.5,
logt≤8.0, logt≤7.0. The CLFs in each passband are constructed with
clusters which are apparently brighter than the respective
completeness magnitude. The Poisson error for every value of the
log10(CLF) given in the table is the same, and is equal to 0.217.
