I/300           PM2000 Bordeaux Proper Motion catalogue       (Ducourant+, 2006)

The PM2000 Bordeaux Proper Motion catalogue (+11°<δ<+18°) Ducourant C., Le Campion J.F., Rapaport M., Camargo J.I.B., Soubiran C., Perie J.P., Teixeira R., Daigne G., Triaud A., Requieme Y., Fresneau A., Colin J. <Astron. Astrophys. 448, 1235 (2006)> =2006A&A...448.1235D (SIMBAD/NED BibCode)

The catalogue has a limiting magnitude V=16.2 (Bordeaux CCD meridian circle magnitude) and is complete down to V=15.4. Depending on magnitude, the positional precision at mean epoch ranges from 50 to 70mas and the precision of proper motions varies from 1.5mas/yr to 6mas/yr. Meridian V magnitudes are provided for all objects together with additional photometry from the 2MASS catalogue when available (99.5% of objects). Positions and proper motions are on the ICRS (International Celestial Reference System). Proper motions are derived from the comparison of the positional M2000 catalogue (systematic observations of the Bordeaux Carte du Ciel Zone with the meridian circle, completed in 2000) with positions derived from the reduction of 512 Carte du Ciel plates of the Bordeaux zone (scanned at the APM Cambridge), the AC2000.2 catalogue, the USNO-A2.0 catalogue and the unpublished Yellow Sky (YS) USNO catalogue. Systematic offsets in 2MASS positions and in UCAC2 proper motions were revealed from comparisons with PM2000. File Summary:

Note (1): The bandpass is defined by two combined filters (GC495 and BG38) as the wavelength range 520-680nm; This is different from Tycho Vt. Note (2): V-Ks = 99.999 when no K measurement was available in 2MASS. Note (3): This goodness of fit is the ratio of the scatter-based and the model-based error.
