Description:
This composite catalogue contains 180812 positions and magnitudes of
176591 stars north of declination -40deg, 155005 proper motions, and
25848 positions and magnitudes of 184 Solar System objects obtained
with the Carlsberg Automatic Meridian Circle on La Palma during the
period May 1984 to May 1998. It includes Carlsberg Meridian Catalogues
Numbers 1 to 11 (CMC1-11); i.e. it comprises all the observations made
since the instrument began operation on La Palma. The positions of the
stars are for the epoch of observation and the equinox J2000.0, and
are referred to the new International Celestial Reference Frame. The
limiting magnitude is V=15.4.
The catalogue mainly comprises positions and proper motions for the
following programmes:
36000 International Reference Stars
30000 faint reference stars in a global net
18000 reference stars in the fields of radio sources
17000 stars in the Lick Northern Proper Motion catalogue
5000 reference stars for calibration of Schmidt plates
2600 stars in the Gliese catalogue of nearby stars
5000 stars in nearby OB associations
10500 F-type stars within 100 pc
9000 G-type dwarfs and giants, K-type giants stars within 300 pc
2200 unbiassed sample of K/M-type dwarf stars
19400 reference stars near Veron-Cetty galaxies
4700 variable stars (12-14 mag) in GCVS
12400 stars (11-14 mag) with pm>0".18/yr in NLTT
and several smaller programmes mainly aimed at galactic kinematics.
Positions and magnitudes of 12 novae and 8 supernovae which occurred
in the years 1991 to 1998 are included.
The catalogue also contains observations of the following Solar System
objects: Callisto, Ganymede, Rhea, Titan, Iapetus, Hyperion, Uranus,
Oberon, Neptune, Pluto and 173 minor planets and Comet P/Wild2.
The mean error of a catalogue position in the zenith is 0".09 in right
ascension and declination in CMC1-6, improving to 0".06 in CMC7-11.
The accuracy in magnitude is 0.05 mag in CMC1-10, improving to 0.03
mag in CMC11. The mean error of the proper motions, derived by
combining the position in this catalogue with those at earlier epochs,
is typically in the range 0".003 to 0".004 per year.
Cross-references are given to DM, AGK, SAO, HD and the double star
catalogues ADS and WDS.
The catalogue also contains 12216 mean annual observed positions of
the FK5 stars used to transfer the instrumental system to the FK5
frame in the years 1984 to 1995.
A compilation of all the meteorological data collected in the years
1984-1998, including the atmospheric extinction, is appended.
This catalogue supersedes the previous versions which were numbered
I/126 (CMC1 and 2), I/133 (CMC3), I/147 (CMC4), I/170 (CMC5),
I/189 (CMC6), I/205 (CMC7) and I/213 (CMC8).

Note (1): Individual magnitudes may be given in the file varmag.dat.
Note that the number of observations of the magnitude o_Vmag is the
number of consistent observations used in forming the mean magnitude.
Since these stars are variable, the number of observations may be
given as zero, when in fact there are observations (in varmag.dat).
Where no observation of magnitude was made, the magnitude was either
taken (to one decimal place) from an input catalogue or it was
assigned a nominal magnitude of 12. Note also that nights with just a
few clouds were not normally flagged as non-photometric, so some false
faint magnitudes could be expected.

Global Notes:
--------------------------------------------------------------------------------
Note (G1): the CMC number is built as
CMC = Vol*100000 + serialNumber.
Note (G2): For the stars with no magnitude determination, the magnitude
was either taken (to one decimal place) from an input catalogue,
or it was assigned a nominal magnitude of 12. If the star is present
in the General Catalogue of Variable Stars, the faintest observed
magnitude is given, followed by a `V'. The individual observed
magnitudes for these stars may be given in the file varmag.dat.
Besides `V', the other flags may be:
Y or I: approximate magnitude
X or R: magnitude was set to 12.
Note (G3): the proper motions are derived independently for each entry
of the star (see details in the documentation, section 8)
