INTRODUCTION

On the basis of original measurements of proper motions of stars from the catalogs FONAK 1.1, HIP�PARCOS, Tycho�2, UCAC2 (up to +40° in declination and up to +52° in separate regions), UCAC3,CMC (STAR 11), PPM, PPMX, NPM1, NPM2, XZ80Q, Pul�3, Pul2, NLTT, LHS, GCVS, LowellProper Motion, and Bruce Proper Motion, as well as data from approximately 800 other publishedsources, we compiled a catalog of stars with high proper motions. Motions exceeding 40 mas/year in sumin both coordinates were assumed to be high. In a declination coverage from –2.5° to +90° up to a limitingstellar magnitude of 16m (up to 17m for companions in multiple systems) there turned out to be 4 302 200such stars in our list (there were 514 100 stars in version 2.0). These stars are of certain interest when car�rying out different stellar�statistical works, in particular, for the determination of a luminosity function inthe solar neighborhood, for the determination of coordinates of the solar apex [1], for the calibration of astellar magnitude scale, and for the solving of other problems. Using J, H, and K magnitudes of the cata�logs PPMX and UCAC3, common stars (approximately 4570) with known B, V, R, and I magnitudes andspectra were found to determine conversion coefficients and then to calculate R(c) values for all stars ofPPMX and UCAC3 in catalog [2].

In addition to astrometric data (equatorial and galactic coordinates, proper motions, estimates of stel�lar magnitudes), astrophysical characteristics were included in the catalog; they are: accurate (up to 0.05m)stellar magnitudes in the system V (223600 determinations), B or B – V (197400 determinations), U orU – B (7400 determinations), R or V – R (6200 determinations), I or R – I, V – I (26000 determinations),J (4137200 determinations), H (4137200 determinations), K (4137200 determinations); metallicity[Fe/H] or [M/H] (4300 determinations), radial velocity (6800 determinations), spectrum, luminosityclass; flags on system’s multiplicity, variability (4200 stars), and other characteristics. For convenience ofuse, star numbers from different catalogs and the author’s star lists, as well as main source numbers thatserved as a base for the catalog creation, are given. It happens often that one and the same star has differentidentification in different catalogs. An identification list of such stars has been compiled [3]. To date, thecatalog includes codes of 67 catalogs and the author’s star lists. The catalog is located at the site of theMain Astronomical Observatory, National Academy of Sciences of Ukraine: ftp://ftp.mao.kiev.ua/pub/astro/h�pms3.dat.

The star array is ordered by right ascension. Information on a star is written in the digital integer formby one line of 322 symbols. The presence of additional information (e.g., several estimates of stellar mag�nitude, radial velocity) increases the number of lines assigned to one star. With regard to this fact, the totalnumber of lines is 4534900.

The reliability of results of the solving of any of the above�mentioned problems depends on the com�pleteness of a star sample in a concrete interval of stellar magnitudes and proper motions. In our case, thesample will be more or less complete up to 15.5–16.0m (approximately 85% according to estimates) for allvalues of proper motions that are more than 40 mas/year, in the stellar�magnitude interval chosen by us.

Abstract—We compiled a catalog (containing astrometric and astrophysical characteristics) of 4 302200 stars with high proper motions (no less than 40 mas/year) using original measurements of propermotions of stars from the catalogs FONAK 1.1, HIPPARCOS, “Tycho�2,” UCAC2,3, CMC (STAR 11),PPM, PPMX, NPM1, NPM2, XZ80Q, Pul�3, Pul2, NLTT, GCVS, LHS, “Lowell Proper Motion,”and “Bruce Proper Motion,” as well as some data from approximately 800 other published sources.The location of our catalog is ftp://ftp.mao.kiev.ua/pub/astro/h�pms3.dat.

CATALOG OF STARS WITH HIGH PROPER MOTIONS (VERSION 3.0) 259

Contributions of main catalogs to the general list of stars are 0.5% for Pul3, 0.5% for Luyten, 1.5% for“Carte du Cial (Bordo)”, 1.5% for FONAC�1.1, 1.5% for HIPPARCOS, 7.0% for Tycho�2, 19.0% forPPMX, and 68.5% for UCAC2,3.

Let us consider a concrete data record table for each star. A more detailed description of the table isgiven in the site.

Values of right ascension, declination, proper motion, stellar magnitude, radial velocity, and othercharacteristics that are given in the catalog were taken together with their determination errors in theirsources. For a source that served as a base for coordinates and proper motions, its number, as a rule, waswritten down in the last column assigned to a number (positions 35–38). If values of coordinates andproper motions differed within the limits of a 2σ accuracy of their determination in sources, their esti�mates were averaged and source numbers were written down in positions 31–34 and 35–38. The averagingwas carried out too, if values of characteristics for a concrete star which were taken from different sourcesdiffered within the limits of 0.01–0.02m for stellar magnitude, of 1 km/s for radial velocity, and of 0.1 for

In the case of writing of information on a star inseveral rows, a blank was written down in columns “declination (B1950.0, J2000.0),” “proper motion,”and “epoch,” starting from the second row. If there were additional accurate coordinates and propermotions, these values were put into corresponding columns for J2000.0.

The information on the catalog is supplemented regularly.
