The CATS Database to Operate with Astrophysical Catalogs
نویسندگان
چکیده
A public database of astrophysical (radio and other) catalogs (CATS), has been created at the Special Astrophysical Observatory (SAO). It allows a user to execute a number of operations in batch or interactive mode, e.g., to obtain a list and parameters of catalogs, to extract objects from one or several catalogs by various selection criteria, to perform cross-identification of different catalogs, or to construct radio spectra of selected sources. Access to CATS is provided in both dialog mode (non-graphical), and graphics mode (hypertext, via Tcl/Tk or possibly Java in future). The result of CATS operation can be sent to the user in tabular and graphical formats.

We describe the current status of CATS, a publicly accessible database (web-server http://cats.sao.ru) allowing one to search in hundreds of catalogs of astronomical objects discovered all along the electromagnetic spectrum. Our emphasis is mainly laid on catalogs of radio continuum sources observed from 30 to 15000 MHz, secondly on catalogs of objects such as raIn 2004 CATS comprised a total o...

متن کاملA general method of estimating stellar astrophysical parameters from photometry
Context. Applying photometric catalogs to the study of the population of the Galaxy is obscured by the impossibility to map directly photometric colors into astrophysical parameters. Most of all-sky catalogs like ASCC or 2MASS are based upon broad-band photometric systems, and the use of broad photometric bands complicates the determination of the astrophysical parameters for individual stars. ...

We describe the main principles of formation of databases (DBs) with information about astronomical objects and their physical characteristics derived from observations obtained at the Crimean Astrophysical Observatory (CrAO) and published in the “Izvestiya of the CrAO” and elsewhere. Emphasis is placed on the DBs missing from the most complete global library of catalogs and data tables, VizieR...
متن کاملMachine Learning Etudes in Astrophysics
Making mock simulated catalogs is an important component of astrophysical data analysis. Selection criteria for observed astronomical objects are often too complicated to be derived from first principles. However the existence of an observed group of objects is a wellsuited problem for machine learning classification. In this paper we use one-class classifiers to learn the properties of an obse...
