Description:
The USNO Flagstaff Station Image and Catalogue archive
provides access to digitized images of the major Schmidt photographic surveys of the sky (POSS-I, POSS-II, SERC-J, SERC-R, SERC-EJ, SERC-ER, AAO-R etc.) and to astrometric catalogues derived from these data, including USNO-A2, USNO-B1 and NOMAD. The site provides catalogue data, finding charts, image data and a merge of the three.

This is a course on using the Virtual Observatory (VO), an
international research data infrastructure in Astronomy and
Astrophysics. Starting with a brief discussion of some general
concepts, it introduces some of the major client programs like TOPCAT
and Aladin, together with some simple discovery protocols. A first
focus topic is the query language ADQL, which is treated within the
equivalent of three lectures. The second major focus of the course is
the premier Python interface to the VO, pyVO, which is used to also
more deeply investigate the topics treated before. The course is
complemented by a number of side tracks, brief discussions of more
fundamental or more specialised VO topics.
The course comes with many exercises, most of which also have
solutions. We hope it is suitable for both self-study and as lecture
notes in teacher-led situations. In the latter case, it is designed to
work as a semester-long course with two hours of lectures and lab work
each per week.

Description:
USNO-A2.0 is a catalog of 526,280,881 stars, and is based on a re-reduction of the Precision Measuring Machine (PMM) scans that were the basis for the USNO-A1.0 catalog. The major difference between A2.0 and A1.0 is that A1.0 used the Guide Star Catalog (Lasker et al. 1986, see Cat. <I/220>) as its reference frame whereas A2.0 uses the ICRF as realized by the USNO ACT catalog (Urban et al. 1997, see Cat. II/246>). A2.0 presents right ascension and declination (J2000, epoch of the mean of the blue and red plate) and the blue and red magnitude for each star. Usage of the ACT catalog as well as usage of new astrometric and photometric reduction algorithms should provide improved astrometry (mostly in the reduction of systematic errors) and improved photometry (because the brightest stars on each plate had B and V magnitudes measured by the Tycho experiment on the Hipparcos satellite). The basic format of the catalog and its compilation is the same as for A1.0, and most users should be able to migrate to this newer version with minimal effort. (1 data file).

Description:
USNO-B is an all-sky catalog that presents positions, proper motions, magnitudes in various optical passbands, and star/galaxy estimators for 1,042,618,261 objects derived from 3,643,201,733 separate observations. The data were obtained from scans of 7435 Schmidt plates taken for the various sky surveys during the last 50 years. USNO-B1.0 is believed to provide all-sky coverage, completeness down to V=21, 0.2" astrometric accuracy at J2000, 0.3 mag photometric accuracy in up to five colors, and 85% accuracy for distinguishing stars from nonstellar objects. A brief discussion of various issues is given here, but the actual data are available from the US Naval Observatory Web site and others.
