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.

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 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)
