ADC_Keywords: Positional data ; Proper motions ; Surveys Keywords: astrometry - proper motions - star catalogues Description: PPM-Extended (PPMX) is a catalogue of 18,088,919 stars containing astrometric and photometric information. Its limiting magnitude is about 15.2 in the GSC photometric system. PPMX consists of three parts: a) a survey complete down to RU=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. File Summary:

Note (1): PPMX consist of 3 parts designated as follows: S = a survey S of stars brighter than R=12.8, consisting of 5,620,114 stars H = 874,934 stars fainter than the survey limit have measurements in the AC and therefore highly accurate proper motions O = all other stars (11,593,871). Note (2): These columns give the star identifiers in the following catalogues: H = the ARIHIP catalogue (Wielen et al., 2001VeARI..40....1W) T = the Tycho-2 catalogue (Hoeg et al. 2000, Cat. I/259) P = the PPM catalogue (Roeser & Bastian, 1991, Cat. I/146, I/193) S = STARNET catalogue (Roeser 1996, IAU Symp. 172, 481) G = the Guide Star Catalog 1.2 (Morrison et al., 2001, Cat. I/254) A = the AC2000.0 catalogue (Urban et al., 2001, Cat. I/275)
