All-Sky Compiled Catalogue of 2.5 million stars
The All-Sky Compiled Catalogue of 2501313 stars (ASCC-2.5) with the limiting magnitude V=12-14 is a result of a merging of star lists from present day large high-precision... -
The Tycho Reference Catalogue
The Tycho Reference Catalogue (TRC) contains high-quality positions and proper motions for 990182 stars of the Tycho Catalogue. The proper motions were derived from Tycho... -
The ACT Reference Catalog
The U.S. Naval Observatory has completed the compilation of the ACT Reference Catalog, containing 988,758 stars covering the entire sky. The motivation behind the ACT was to... -
Toulouse AC Zone Data Reduced to ACRS
The U.S. Naval Observatory is in the process of making new reductions of the Astrographic Catalogue (AC) using a modern reference system, the ACRS, which represents the system... -
Radio-optical Reference Catalog, Version 1 (RORC-1)
The fundamental celestial reference frame (CRF) is based on two catalogs of astrometric positions: the third realization of the International Celestial Reference Frame (ICRF3),... -
EUVE optical atlas
The Extreme Ultraviolet Explorer (EUVE) has been detecting EUV sources since its launch in June 1992. Positions of 540 sources have been made available to the community by the... -
Photometry in open cluster NGC 5822
The study presents photoelectric photometry of stars in NGC 5822 on the UBVR and DDO systems. The BV data are employed to calibrate a photographic survey of the cluster, while... -
Isolated galaxies ident. with IRAS and NVSS
We determine some parameters of the far infrared radiation for a sample of isolated galaxies, namely, luminosity, color indices, dust temperature, and current star formation... -
XMM-Newton/2dF survey. II.
In this paper we investigate the properties of low X-ray-to-optical flux ratio sources detected in a wide-area (2.5{deg}^2^) shallow [fX(0.5-8keV)~10^-14^erg/s/cm^2^] XMM-Newton... -
Identifications of objects from RC Catalog
Results from a continuing program for identification of sources from the RC catalog (from observations with the RATAN-600 radio telescope) with the APM (Automatic Plate... -
Optical Identification of RC and UTRAO Catalogs
Two hundred and forty radio sources that are common for RC (RATAN-600) and UTRAO (VLA, Douglas J.N.+, 1980PAUTx..17....1D) catalogs were identified on the enlarged prints of the... -
Far-UV photometry in Ori
(no description available) Cone search capability for table J/ApJS/89/259/table1 (Objects detected in the UV) -
Blazars with {gamma}-ray counterparts. II.
A significant fraction (~30%) of the high-energy gamma-ray sources listed in the second Fermi Large Area Telescope catalog (2FGL) are still of unknown origin, being not yet... -
Blazars with {gamma}-ray counterparts. I.
We present a new method for identifying blazar candidates by examining the locus, i.e., the region occupied by the Fermi {gamma}-ray blazars in the three-dimensional color space... -
Optical SNR candidates in M83
We present a new optical imaging survey of supernova remnants (SNRs) in M83 (NGC 5236), using data obtained with the Magellan I 6.5m telescope and IMACS instrument under... -
2MASS interferometric calibrator candidates
We aim to provide a list of sources found to be unresolved from direct observations with high angular resolution and dynamic range, which can be used to choose interferometric... -
Counterparts to 1.4GHz sources in ECDF-S
We study a sample of 883 sources detected in a deep Very Large Array survey at 1.4GHz in the Extended Chandra Deep Field South. This paper focuses on the identification of their... -
XDEEP2 survey catalog
We present the X-ray point-source catalog produced from the Chandra Advanced CCD Imaging Spectrometer (ACIS-I) observations of the combined ~3.2deg^2^ DEEP2 (XDEEP2) survey... -
Swift-INTEGRAL X-ray (SIX) survey
The supermassive black holes at the center of active galactic nuclei (AGNs) are surrounded by obscuring matter that can block nuclear radiation. Depending on the amount of... -
The Chandra COSMOS survey. III.
The Chandra COSMOS Survey (C-COSMOS) is a large, 1.8Ms, Chandra program that has imaged the central 0.9deg^2^ of the COSMOS field down to limiting depths of...
