Description:
Apertif is a phased-array feed system for the Westerbork Synthesis Radio Telescope (WSRT), providing forty instantaneous beams over 300 MHz of bandwidth. This data release includes the catalogue and image observed by Apertif covering 26.5 square degree region in the Boötes constellation at 1.4 GHz. The image is a mosaic of 187 Apertif images from 8 different survey observations performed between April 2019 and November 2021. It has an angular resolution of 27×11.5 arcseconds and a median background noise of 40 μJy/beam. From this mosaic, 8994 sources were extracted and the catalogue is complete down to the 0.3 mJy level. This service queries the mosaic image of the Boötes field.
62. APS Galaxies in the North Galactic Pole

APS Galaxies in the North Galactic Pole
Short Name:
VII/214

CDS
Description:
(of PhD Thesis, from Minessota) I am using the Minnesota Automated Plate Scanner (APS) to construct two galaxy catalogs. The Minnesota Automated Plate Scanner Pisces-Perseus Survey (MAPS-PP) is used to search for modern-day remnant signatures of large-scale structure formation processes, specifically, galaxy alignments relative to surrounding large-scale structure. Weak evidence for such alignments is found, although the type of alignments seen don't strongly support any one large-scale structure formation model. Comparison of the MAPS-PP to pre-existing galaxy catalogs has led to the discovery that the Uppsala General Catalog and Third Reference Catalog of Galaxies exhibit a very strong measurement bias: their diameters are measured to different isophotes at different galaxy inclinations. Therefore previous determinations of the diameter function and the internal extinction properties of other galaxies (most of which have relied on one of these two galaxy catalogs) have suffered from a biased diameter measurement. I avoid this bias by using the APS data (which is obtained using automated computer-based criteria for measuring the structural properties of images digitized from photographic plates) to construct a catalog of over 200,000 galaxies within 30 degrees of the North Galactic Pole (the MAPS-NGP). The MAPS-NGP is the deepest galaxy catalog constructed over such a large area of the sky and used to re-evaluate previous investigations of the internal extinction in galaxies.

Publisher:

Description:
We present accurate B1950 and J2000 positions for all confirmed galaxies in the Uppsala General Catalog (UGC, Cat. <VII/26>). The positions were measured visually from Digitized Sky Survey images with rms uncertainties {sigma}<=[(1.2")^2^+({theta}/100)^2^]^1/2^, where is the major-axis diameter. We compared each galaxy measured with the original UGC description to ensure high reliability. The full position list is available in the electronic version only. the major-axis diameter.

Publisher:

Description:
ARI katkat is a catalog of star catalogues in the spirit of G. Teleki's catalog of star catalogs (`1989BOBeo.140..131T`_ and references in there). It contains 2573 catalogs suitable for astrometric usage, starting with Flamsteed (1835) and ending in the 1970ies. For almost all of them, there is a column description file (as PDF, and unfortunately sometimes in German) and the digitized content. .. _1989BOBeo.140..131T: http://ads.g-vo.org/abs/1989BOBeo.140..131T

Publisher:
The GAVO DC team
Description:
ARI's "Geschichte des Fixsternhimmels" is an attempt to collect all astrometrically useful observations from before ca. 1970 in a way comparable to what has been done to construct the FK* series of fundamental catalogs. About 7e6 published positions are included. In GAVO's DC, we provide tables of identified and non-identified stars together with the master catalog that objects were identified against.

Description:
The catalogue ARIHIP has been constructed by selecting the 'best data' for a given star from combinations of HIPPARCOS data with Boss' GC and/or the Tycho-2 catalogue as well as the FK6. It provides 'best data' for 90 842 stars with a typical mean error of 0.89 mas/year (about a factor of 1.3 better than Hipparcos for this sample of stars).
69. Arizona CDFS Environment Survey, ACES
ID:
ivo://CDS.VizieR/J/MNRAS/425/2116
Title:
Arizona CDFS Environment Survey, ACES
Short Name:
J/MNRAS/425/2116
Date:
21 Oct 2021
Publisher:
CDS
Description:
We present the Arizona CDFS Environment Survey (ACES), a recently completed spectroscopic redshift survey of the Chandra Deep Field-South (CDFS) conducted using the Inamori-Magellan Areal Camera and Spectrograph on the Magellan-Baade telescope. In total, the survey targeted 7277 unique sources down to a limiting magnitude of R_AB_=24.1, yielding 5080 secure redshifts across the ~30'x30' extended CDFS region. The ACES data set delivers a significant increase to both the spatial coverage and the sampling density of the spectroscopic observations in the field. Combined with previously published spectroscopic redshifts, ACES now creates a highly complete survey of the galaxy population at R<23, enabling the local galaxy density (or environment) on relatively small scales (~1Mpc) to be measured at z<1 in one of the most heavily studied and data-rich fields in the sky. Here, we describe the motivation, design and implementation of the survey and present a preliminary redshift and environment catalogue. In addition, we utilize the ACES spectroscopic redshift catalogue to assess the quality of photometric redshifts from both the COMBO-17 and Multiwavelength Survey by Yale-Chile imaging surveys of the CDFS.
