Gaia Data Access - Call for Gaia DR3 User Scenarios: we need your input!

With the recent release of Gaia DR2, the community is now asked to review the current set of Data Access Scenarios, and submit new data access scenarios, which will be considered for future implementation to support the development of the Gaia Archive system in the release of Gaia DR3 and the following Gaia DR4 release. The data release page gives an indication of the range of Gaia data products currently planned for release in the upcoming data releases.

Your help in describing how you wish to access the Gaia Data through the ESA Gaia archive and/or other access points is very valuable in helping the Gaia project develop and deploy the best possible interfaces and tools to help you, the science community, access and work with the Gaia data.

This call is open until December 2018. Please see the GREAT wiki page for details as to how to add new scenarios. Information on how to sign up are given on the home page under "A note on registering for the wiki”.

Did you know…

Did you know that as of today, Gaia took more than 21 billion spectroscopic CCD measurements, more than 225 billion photometric CCD measurements and more than 1 trillion astrometric CCD measurements. The number of objects that passed through the Gaia focal plane already surpasses 113 billion, and more than 7 billion objects passed through the RVS instrument. Interested to follow up on some Gaia numbers? Check out our mission numbers page.
Did you know that Gaia sent out more than 100 photometric science alerts in November alone on supernovae, transients, flaring stars and more, interesting for following-up with other observatories. More information can be found on the Gaia Photometric Science Alerts webpage.
Did you know that Gaia also sends out alerts on Solar System objects? These are distributed by the Gaia Follow-Up Network for Solar System Objects (Gaia-FUN-SSO). A total of more than 3400 alerts have been sent out since the first trigger was announced.

Important resources for users of Gaia data

Most important resources to understand the processing and content of Gaia data release 2 are the data release documentation and data release papers. The A&A special edition on Gaia Data Release 2 is now out as well and can be found here.

Each data release comes with its own citation guidelines. Please remember to add the acknowledgement and cite the relevant papers. This will greatly help us to argue for continued funding of the data processing effort and possible mission extensions.

To quickly get up to speed using Gaia data and be warned about the limitations of the data, check out the Gaia DR2 Guide for Scientists. These are short videos on very specific topics like “Validation”, “Apsis results”, “radial velocities”, “on the use of parallaxes”, and many more based on skype interviews with the Gaia DPAC experts on the subject.

Get your updates on newly found issues in Gaia Data Release 2 here, or read through some Archive tips and FAQ on data access

Wondering how to upload a table and use this in combination with Gaia data? Check out the "White Dwarfs Exploration tutorial". Wondering how to deal with large queries and timeouts? Check out the “query timeouts tutorial”. Wondering where to find the light curves? Check out the explantion of the Datalink Service and the “Datalink and light curves tutorial” Check out those and various other tutorials available from the Help tab at the Gaia Archive.
