The epoch International Celestial Reference Frame (epoch ICRF) is proposed as a new concept in order to consider the effect of apparent proper motion of the position of a radio...

The Photoelectric Astrolabe Mark I (PHA I) has been revised with a new combined prism which could work as an almucantar with zenith distance of 45 degree, to measure continuous...

We present a remeasurement of old photographic plates, providing important raw data for dynamical studies of the Saturnian satellite system. The unprecedentedly accurate...

The Wide-Field Plate Database (WFPDB) contains the descriptive information for the astronomical wide-field (~>1deg.) photographic observations stored in numerous archives all...

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...

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....

(no description available) Cone search capability for table VI/116/dfbs (The Digitized First Byurakan Survey (DFBS) plate database)

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...

We compiled a catalog of 421 references 12-15mag stars for determining accurate positions of objects in the region of M 31. We also compiled a star chart, which is provided as...

Using the data observed in San Juan with the photoelectric Astrolabe Mark II of the Beijing Astronomical Observatory from February, 1992 through March, 1997, the radio stars...

On the photon counter data observed with Photoeleetric Transit Instrument of Beijing Astronomical Observatory during the period from 1988 to 1990, corrections of right...

On the basis of the data observed with the Photoelectric Transit Instrument, of the Beijing Astronomical Observatory during the period from 1980 through 1984, the third...

The authors present an observational catalogue containing the positions of 351 stars situated in the vicinity of radio sources (RRS2, Tel'nyuk-Adamchuk & Kumkova, 1991, IAU...

Using the powerful Earth-occultation technique, long-term, nearly continuous monitoring of the entire low-energy gamma-ray sky is now possible with the advent of BATSE, the...

We present interplanetary network localization information for 218 gamma-ray bursts in the third BATSE catalog obtained by analyzing the arrival times of these bursts with the...

We present infrared K-band photometry of complete samples of VLM candidates constructed from IIIaF and IVN plates in 10 fields taken as part of the POSSII and UKSRC surveys....

UBVRI photoelectric observations have been made of 109 stars around the sky, centered more or less at -50{deg} declination. The majority of the stars fall in the magnitude range...

We use very long baseline interferometry data obtained between mid-1995 and the end of 2002 May together with older data to extend and revise the International Celestial...

This paper presents new positions for 689 FK5 stars determined directly in the extragalactic reference system from CCD scan observations made with the Flagstaff Astrometric...

BVR photoelectric photometry and positions are reported for 437 stars in 49 Palomar Sky Survey fields. A relation is derived between the Johnson BVR photometry and the E and O...
