Download easily ra,dec,z of all the quasars

Post by MinaGhodsi »

Hi, I would like to download a data table that would allow me to create a full sky map of all the quasars (or AGNs) observed by Erosita. I am above all interested in having the ra, dec, redshift coordinates of the quasars, and maybe I will download additionally the flux/brightness from a few of the channels.

My question: How can I do this? In SDSS it was rather easy, I used SQL commands for that? Is there a way to download Erosita data with SQL, too? Is the Erosita data already hosted in some other databases (e.g. Cosmohub, Simbad) from where I could download it easily? Or is there another easy way to extract the required data from the Erosita data base? Thx

Dear Mina
The Quasar people are working on the catalog and they will make it available as soon as possible, together with the paper.

The catalog will be available via Vizier and on our catalogues_DR1 pages. The catalog will includes also reliable photometric redshifts.

You can contact Mara Salvato (mara at mpe.mpg.de) for clarifications.
