Title:
Preliminary Cat. of Fund. Faint Stars
Short Name:
I/42
Date:

Publisher:
CDS
Description:
The PFKSZ is based on 14 catalogues, observed at 10 observatories (Bucharest, Wroslaw, Kiev, Goloseevo-GAO, Kazan, GAISH, Odessa, Pulkovo, Tashkent, Kharkov). The catalogue PFKSZ contain 587 stars from 7.3 to 8.4 vis.mag. Most of the catalogues have been obtained from differential meridian observations in the FK3 system. The proper motions were found in the FK3 system mainly from GC, AGK2 (or AGK2A), Yale and PFKSZ catalogues. The precision of PFKSZ catalogue is Mean Error(in Alfa x cos Decl.) = +/- 0.0068 timesec Mean Error(in Decl.) = +/- 0.127 arcsec for the mean epoch 1949.0.
442. Preliminary list from Tycho observations (TIC data)

Title:
Preliminary list from Tycho observations (TIC data)
Short Name:
I/207
Date:
21 Oct 2021
Publisher:
CDS
Description:
The selection of the stars of the Tycho program is mainly based on the Tycho input catalogue (TIC), prepared by Egret et al. (1992) from existing ground-based catalogues. The TIC is far to be the definitive list of the stars that will appear in the final Tycho catalogue however. The number of stars included within (3 million) is several times larger than the number eventually expected. The selection of the TIC stars that will remain in the final catalogue is planned in two steps : The former is the "Recognition" that is based on the first year of the scientific mission. The latter step of selection is the final reduction of the Tycho data, which will require a few more years. The recognition was completed in 1992, and, among the 3,154,204 stars of the TIC, about two third were not found in the observations. This catalogue presents the 1,049,971 stars that are still in the programme. The selection is nor definitive, nor complete; but it should contain only a small percentage of stars that will still be discarded. On another side, some stars missing in the TIC have been added to the Tycho program, but the expected number of additional stars to appear in the final catalogue should be about 5 % or less. The list was announced in Halbwachs et al (1994). It is completed with data (coordinates and magnitudes) from the main file of the Tycho Input Catalogue. The cross-identifications with the Hipparcos Input Catalogue or with the INCA database included in catalogue I/197/ are not repeated here.
443. Proper motion data of M10
ID:

Title:
Proper motion data of M10
Short Name:

Publisher:

Description:
We present the first proper motion study of M10 (NGC 6254). Absolute proper motions of about 532 stars in the field of the globular cluster M10 were determined with respect to Hipparcos and ACT reference stars. In addition to photographic plates of Bonn and Shanghai also wide field CCD observations as second epoch plates were used. The wide field CCD observations show an accuracy comparable to that of the photographic plates. A good coincidence of the solutions based on reference stars from Hipparcos and from ACT was found. Our final proper motions allow a sufficient separation of cluster and field stars. Two population II Cepheids were confirmed to be members of M10. The absolute proper motion of M10 was determined and combined with its distance from the Sun and its radial velocity. The space motion and metallicity of M10 indicates the characteristics of a halo object with an orbit reaching to a maximal z-distance of less than 3kpc.
444. Proper motions and astrometry of late-type dwarfs
ID:
ivo://CDS.VizieR/J/AJ/137/1
Title:
Proper motions and astrometry of late-type dwarfs
Short Name:
J/AJ/137/1
Date:
21 Oct 2021
Publisher:
CDS
Description:
We report proper-motion measurements for 427 late-type M, L, and T dwarfs, 332 of which have been measured for the first time. Combining these new proper motions with previously published measurements yields a sample of 841 M7-T8 dwarfs. We combined parallax measurements or calculated spectrophotometric distances, and computed tangential velocities for the entire sample.

Description:
The main astrophysical parameters of 24 previously unstudied open clusters of Berkeley catalogue are presented here. JHK near-infrared (Two Micron All Sky Survey, Cat. II/246) photometry and the proper motions astrometry of Naval Observatory Merged Astrometric Dataset (NOMAD, Cat. I/297) are used. The clusters' centres, angular diameters, ages, distances and colour excesses for these clusters are estimated for the first time.

Description:
This catalog, listing the proper motions of 20,843 stars from the Cape Astrographic Zones, was compiled from three series of photographic plates. The plates were taken at the Royal Observatory, Cape of Good Hope, in the following years: 1892-1896, 1897-1910, 1923-1928. Data given include centennial proper motion, photographic and visual magnitude, Harvard spectral type, Cape Photographic Durchmusterung (CPD) identification, epoch, right ascension and declination for 1900.

Title:
Proper Motions in Praesepe
Short Name:
I/257B

Publisher:
CDS
Description:
High-precision proper motions for 257 and 296 stars in a 90'x90' region centered on BD+20 2170 were obtained from seven plates taken with the Zo-se 40cm refractor (f=6895mm) in March, 1986 (see the "Plate Summary" section below), combined with six AC plates and the stellar positions in Russell's (1976, Ph.D. Thesis, Pittsburgh University). Combined with other data, membership probabilities were estimated by an improved maximum likelihood method. A very good sample of 198 members is obtained with proper motion accuracies ranging from +/-0.2 to +/-5.0mas/yr, of which 60% are better than +/-1.0mas/yr; the completeness limit is about B=15.5mag. Note that the table published in electronic form associated to the paper published in 1995A&AS..113..419W presented positions not correctly associated to the stars (see the "History" section below)
449. Proper motions of metal-poor stars
ID:

Title:
Proper motions of metal-poor stars
Short Name:
J/AJ/119/2866
Date:
21 Oct 2021
Publisher:
CDS
Description:
We present a revised catalog of 2106 Galactic stars, selected without kinematic bias and with available radial velocities, distance estimates, and metal abundances in the range -4.0<=[Fe/H]<=0.0. This update of the 1995 Beers & Sommer-Larsen catalog (Cat. <J/ApJS/96/175>) includes newly derived homogeneous photometric distance estimates, revised radial velocities for a number of stars with recently obtained high-resolution spectra, and refined metallicities for stars originally identified in the HK objective-prism survey (which account for nearly half of the catalog) based on a recent recalibration. A subset of 1258 stars in this catalog have available proper motions based on measurements obtained with the Hipparcos astrometry satellite or taken from the updated Astrographic Catalogue (second epoch positions from either the Hubble Space Telescope Guide Star Catalog or the Tycho Catalogue), the Yale/San Juan Southern Proper Motion Catalog 2.0, and the Lick Northern Proper Motion Catalog. Our present catalog includes 388 RR Lyrae variables (182 of which are newly added), 38 variables of other types, and 1680 nonvariables, with distances in the range 0.1 to 40kpc.
450. Proper motions of 555 quasars from VLBI
ID:
ivo://CDS.VizieR/J/A+A/529/A91
Title:
Proper motions of 555 quasars from VLBI
Short Name:
J/A+A/529/A91
Date:
21 Oct 2021
Publisher:
CDS
Description:
While analyzing decades of very long baseline interferometry (VLBI) data, we detected the secular aberration drift of the extragalactic radio source proper motions caused by the rotation of the Solar System barycenter around the Galactic center. Our results agree with the predicted estimate to be 4-6 micro arcseconds per year (uas/yr) towards RA=266{deg} and DE=-29{deg}. In addition, we tried to detect the quadrupole systematics of the velocity field. The analysis method consisted of three steps. First, we analyzed geodetic and astrometric VLBI data to produce radio source coordinate time series. Second, we fitted proper motions of 555 sources with long observational histories over the period 1990-2010 to their respective coordinate time series. Finally, we fitted vector spherical harmonic components of degrees 1 and 2 to the proper motion field.
