Examples of programmes which have been undertaken by the Carlsberg Meridian
Telescope using the old micrometer system are as follows:
-
2000 G-type dwarf stars within 30 pc: derive proper motions for a
kinematically unbiased photometric catalogue to investigate the ``G-dwarf
problem''.
-
6000 reference stars (m = 10-12) in fields of QSOs : derive accurate
positions for reduction of photographic plates, and so derive optical positions
of QSOs to link with radio (VLBI) positions.
-
Astrometric grid of reference stars for constructing a deep CCD image of the
Galactic Centre.
-
18400 reference stars for calibrating the second version of the HST Guide
Star Catalogue.
-
10500 F stars within 100pc: improved proper motions for kinematic
studies.
-
Observations of planets and/or their satellites in the outer Solar System,
mainly for input to the JPL integrations of planetary orbits which are used
in planning space missions.
-
99 minor planets : positions for dynamical studies and magnitudes for
physical studies.
-
Regular observations of novae and supernovae when they occur: data published
in
IAU Circulars.
-
A small number of stars are being monitored for long term brightness
fluctuations. e.g. the mass losing supergiant P Cygni and the recurrent nova
RS Oph.
