Information on Service 'ARI Catalog of Catalogs'

[Use this service from your browser]

Further access options are discussed below

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.

For a list of all services and tables belonging to this service's resource, see Information on resource 'ARI Catalog of Catalogs'

Service Documentation

The digitized content was partially used as an input to the ARIGFH project; for those catalogs processed in this context, the objects contained are given in one of the tables arigfh.identified or arigfh.unidentified.

See also the ARIGFH resource info.

For the benefit for search engines (that will hopefully pick up the bibliographic information), here's a paged copy of katkat:

Overview

You can access this service using:

This service is published as follows:

local means it is listed on our front page, ivo_managed means it has a record in the VO registry.

Other services provided on the underlying data include:

Default Output Fields

The following fields are contained in the output by default. More fields may be available for selection; these would be given below in the VOTable output fields.

VOTable Output Fields

The following fields are available in VOTable output. The verbosity level is a number intended to represent the relative importance of the field on a scale of 1 to 30. The services take a VERB argument. A field is included in the output if their verbosity level is less or equal VERB*10.

The individual catalogs may have other licensing or copyright schemes, but in general a sound citation practice should be all right -- even more so since most of the individual authors are either dead or retired.

Note i

As always in bibliography, nomenclature is at least difficult. For the catalogs, we have no less than for sets of identifiers tied together by katkat.

  • HDWL: This is more or less a running number of catalogs included

    in the catalog list. One HDWL major number roughly corresponds to a book or article, and every publication in katkat has an HDWL number. Some works contain multiple tables; in that case, the HDWL has the form major.minor; minor is a single digit.

  • Teleki: This is a reference into a catalog of catalogs that was maintained

    by G. Teleki (Published in Publ. Astron. Opservatorije Beogr.) and then for a short while continued at ARI. These are simply numbers, but not all publications listed here have a Teleki number. All catalogs that went into identification have one, though. Unfortunately, it is possible that there are multiple Teleki numbers to a single HDWL entry. In that case, the Teleki number included is just one of them.

  • File ID: This is a string containing slashes and parenteses, e.g.

    021/1(434). These refer to input files, where the number after the slash is a running number counting up for a given bibliographical source. Since a single source may give several tables, multiple file ids can refer to a single HDWL number. Since we are primarily interested in the digitized tables, the file id is arigfh.katkat's primary key.

  • teleki/catpv: These are strings of the form t<teleki>p<catpv>. They

    were used for catalogs that were crossmatched with the master catalog. File IDs can correspond to multiple teleki/catpv combinations, when a single input was split into multiple outputs that could be treated together. In katkat, the file has one of the teleki/catpv combinations only, again because we are mainly interested in the files. catpv is a two-digit code consisting of "part" and "version".
