Description
This catalogue presents astrometric (position and proper motion) and photometric parameters for 1250 PMS stars and 104 PMS star candidates spread over all-sky major star-forming regions. We provide for each star the mean (J2000.0) position and proper motion derived from CCD meridian observations(Bordeaux and Valinhos CCD meridian circle), ESOD1.5m and OHP120cm telescopes, Schmidt SERC-J, POSS I and POSS II plates digitized with the MAMA measuring machine (Paris) and published catalogues as AC2000.2 (<I/275>), USNO-A2.0 (<I/252>), HIPPARCOS (<I/239>), Tycho-2 (<I/259>), UCAC2 (<I/289>), 2MASS (<II/246>) and other astrometric sources. We also provide, when available, CCD meridian V magnitude and the J, H, K magnitudes from 2MASS catalogue. Precision on proper motions vary from 2 to 5mas/yr depending on the used sources of ancient positions and depending also on the embedding and binarity of the source. The V limiting magnitude of our catalogue is about 16.5.
