Does anyone know how to access Gaia DR2 or EDR3 time series data for an individual star via a GUI interface?

Internet searches have so far not helped me.

VStar Gaia Plugin

VStar supports a pluging (described here https://www.aavso.org/sites/default/files/vstar-plugins/vstar-plugins-d…) that will display the light curve photometry for the subset Gaia sources that Gaia classifies as variable and supplies epoch photometry.  From my reading of the summary of EDR3 I do not believe any addtional data have been release over DR2.

best regards

VStar Gaia Plugin

Thanks Cliff,

I've got the plugin and will have a good look.

So far, trying to add data to a VStar light curve from Gaia DR2 (via the plugin) yields the response (for a few different variables) "No observations for the specified period".

Gais DR2 phot_variable_flag=“VARIABLE”.

Did you verify that you are looking in the Gaia archive for DR2, not DR3?  Is the phot_variable_flag set to "VARIABLE"?

If so, please share the Gaia IDs you are searching.

Hello Roy,

Hello Roy,

 

since the release of DR3 photometry in June, the individual photometry measurements are available on https://gaia.ari.uni-heidelberg.de/singlesource.html

This webpage works very well and is very quick in its responses.
