- Description:
- The "Lick Observatory Sky Atlas" (Lick Observatory, 1965) is a set of plates for 166 fields of 18 by 18 degrees, covering the sky from the north pole down to -30 degrees of declination. "The Mount John University Observatory Photographic Sky Survey" (Doughty et al., 1972) covers 142 similar fields from -15 degrees of declination down to the south pole. In the region of overlap, the fields are the same for the two surveys. Fields 1-46 of the Mount John survey cover the part of the sky (-45 degrees of declination to the south pole) not in the Lick survey; in a special limited edition published in 1972, this part is called the "Canterbury Sky Atlas" (Australia). The overlap between fields is 3 degrees. The plate scale is approximately 232 arc seconds per millimeter. The limiting magnitude is approximately 16. Neither survey is intended for astrometry or photometry; the Lick survey was originally done to obtain galaxy statistics (Shane and Wirtanen 1967). An excellent summary of several photographic sky surveys is given by Ingrao and Kasparian (1967). T. A. Nagy (1980) generated the dataset described, and also gathered most of the material used in the writing of this document.

- Description:
- The catalog contains the coordinate of the plate centers forming the Second Epoch Palomar Oschin Schmidt Sky Survey (POSS-II), observed between 1985 and 2000, and covering the Northern sky. The survey was operated by the California Institute of Technology (CalTech) with funds from the National Science Foundation (NSF), the National Geographic Society, the Sloan Foundation, the Samuel Oschin Foundation, and the Eastman Kodak Corporation. The file "poss2.dat" was actually created from a merge of the UKST Plate Catalogue (Royal Obs. Edinburgh) and the POSS2 Photographic Survey Plate Logs (Naval Observatory)

- Description:
- The "ESO/SRC Atlas of the Southern Sky" is a major tool for, among other things, the optical identification of sources in non-optical wavelengths. The catalog contains the coordinates of the plate centers, as well as the actual observation dates of the plates composing the ESO(B) Survey (also called the Quick Blue Survey) over in the period 1973/79, the ESO Red survey, observed in the period 1978/90, and the SRC-J survey at the Anglo-Australian telescope in the period 1974/1987.

- Description:
- This catalog contains plate-center and observational data for all plates of the National Geographic Society and Palomar Observatory Sky Survey (POSS) and its Whiteoak Extension. The POSS proper consists of photographic reproductions of red-sensitive (Kodak 103a-E) and blue-sensitive (Kodak 103a-O) plates taken of 937 different fields with the 48-inch Palomar Schmidt telescope, covering the entire sky above -33 degrees declination. This southern limit was extended to about -45 degrees by J.B. Whiteoak using the same instrument for a series of 100 photographs that have come to be known as the Whiteoak Extension; thus, the survey as a whole includes 1037 fields. This version of the catalogue consists of plate information reproduced from the Catalogue of Plates and plate information on the Whiteoak Extension derived from file headers of the SAOPSS II tape (Lund and Dixon 1973). The fields of the catalog are POSS number, modified Luyten-Palomar (MLP) number, equatorial coordinates of the plate center (B1950), limits of the right ascension on the plate in radians, galactic coordinate of the plate center, number of SAO stars on the plate, observing dates and times, the hour angles for the observations, length of exposure, and seeing rating. The following basic quantities were taken directly from the Catalogue of Plates: POSS number, exposure dates and times, hour angles, seeing ratings, and coordinates in sexagesimal units. The following derived quantities were calculated at the ADC: MLP number, equatorial coordinates in radians, right ascension limits, galactic coordinates, and number of SAO stars.

- Precise astrometry with VLBA (VIPS)

- Description:
- We present accurate positions for 857 sources derived from the astrometric analysis of 16 eleven-hour experiments from the Very Long Baseline Array imaging and polarimetry survey at 5GHz (VIPS). Among the observed sources, positions of 430 objects were not previously determined at milliarcsecond-level accuracy. For 95% of the sources the uncertainty of their positions ranges from 0.3 to 0.9mas, with a median value of 0.5mas. This estimate of accuracy is substantiated by the comparison of positions of 386 sources that were previously observed in astrometric programs simultaneously at 2.3/8.6GHz. Surprisingly, the ionosphere contribution to group delay was adequately modeled with the use of the total electron content maps derived from GPS observations and only marginally affected estimates of source coordinates.

- 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.

- Description:
- We have used COSMOS scans of photographic plates taken by the Palomar Oschin Schmidt telescope (as part of the original Palomar Sky Survey) and by the UK Schmidt telescope to obtain proper motions for ~ 450 000 stars within a 112-degree region covering part of the Hyades cluster. With epoch differences of 33 to 37 yr, we have obtained proper motions accurate to 6-12 mas/yr and have identified 393 candidate Hyads to a limiting magnitude of Mv ~ +15.5, including at least two new white dwarf candidates. The main-sequence luminosity function determined from our sample is similar to that defined by local field stars, with a broad maximum at Mv ~ +12. Deriving distances from mu u, the proper motion towards the convergent point, and the space velocity determined by Gunn et al., we find stars with motions consistent with membership at distances of more than 15pc from the cluster centre. Moreover, both the line-of-sight and surface density distributions show evidence for significant mass segregation - indeed, the overall proper motion distribution suggests a tight core centred within a much broader distribution. We derive a total mass of 410-480Sun and a gravitational binding radius of ~ 10.5pc.

- Description:
- Pulkovo catalogue of reference stars inside 78 fields around galactic radio stars (Pul GRS) of northern sky from H.G. Walter's list (1990A&AS...86..357W) was created. The coordinates of 12495 stars was obtained from the photographic plates of Pulkovo Normal Astrograph (NA, 33/346), which was photographed in 1994-1999 years. Size of worked fields (radius about 20-40 angular seconds) was determined from the resolved problem and having technical resources: modern dimensions of CCD-detector. Precise astronometric coordinates of stars were intending for optical control beyond the positions of radio sources (GRS) by means of CCD-observation. The galactic radio stars can be the frames at the definition of connection between the existed ground and cosmic astronometric reference coordinate sets. Coordinate calculation was realization with used reference stars from catalogue Tycho-2 (ICRF, J2000.0). Error of a unit of weight from reduction coordinates was resulted nearly 0.12"-0.27" (at a number of reference stars were from 12 to 50). Internal precision of catalogue was obtained from 0.02 to 0.20 arcseconds at the both coordinates.

- Description:
- The catalogue PVC96 is published. This is the first version of catalogue of declinations of FK5 (<I/149>) fundamental stars derived from the observations made with the Zverev photographic vertical circle (PVC) of the Pulkovo observatory in 1987-1994. The given comparison of the PVC96 with the HIP (<I/196>) catalogue obtained by the Hipparcos space project demonstrates that mean error of declination in the PVC96 is 0.1arcsec which corresponds to estimation made a priori.
