Download easily ra,dec,z of all the quasars
Posted: Fri Feb 23, 2024 2:47 pm
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
