PPMX Catalog of positions and proper motions
Listed in IVOA Registry (Virtual Observatory)
PPM-Extended (PPMX) is a catalogue of 18,088,919 stars containing astrometric and photometric information.
Description
Its limiting magnitude is about 15.2 in the GSC photometric system. PPMX consists of three parts: a) a survey complete down to R_U_=12.8 in the magnitude system of UCAC2; b) additional stars of high-precision proper motions, and c) all other stars from GSC 1.2 identified in 2MASS.
The typical accuracy of the proper motions is 2mas/y for 66 percent of the survey stars (a) and the high-precision stars (b), and about 10mas/y for all other stars. PPMX contains photometric information from ASCC-2.5 and 2MASS.
