through TAP and PYVO services.

Dependencies: numpy, scipy, pandas, pyvo

Dependencies: numpy, scipy, pandas, pyvo

Example of session with TAP:

To install pyvo: 

>sudo pip install pyvo

Example of session with TAP: selection of a list of cases

>import pyvo as vo

>import pyvo as vo

>tap_service = vo.dal.TAPService("http://archives.ia2.inaf.it/vo/tap/exo")

>tap_service = vo.dal.TAPService("http://archives.ia2.inaf.it/vo/tap/exo")

>tap_results = tap_service.search("SELECT top 1 exp_id, url FROM exo.EXO")

>tap_results = tap_service.search("SELECT top 1 exp_id, url FROM exo.EXO")

>print(tap_results)

>print(tap_results)

>len(tap_results)

>len(tap_results)

>tap_results.getrecord(0)

>tap_results.getrecord(0)

To install pyvo: 

>sudo pip install pyvo

Example of session using Artecs.tap

Example of session with TAP: download of a fits map of temperatures
