Auxiliary data

Any data that is provided to support the use of Gaia data or explain the Gaia Data Processing and Analysis in more depth are summarised below:


Gaia EDR3 extinction law

A set of coefficients which allow the computation of the Gaia EDR3 extinction law is provided here along with information on the computation.


The photometric system of Gaia

Pre-launch passbands (applicable to Gaia DR1)

Gaia DR2 passbands (More info on the Gaia DR2 known issues page as well)

Gaia EDR3 passbands


Scanning law

Find here the sampling of the Gaia scanning law for the time period of Gaia DR2 observations.

Gaia scanning law pointings for the time period of Gaia EDR3 are available from the Gaia Archive.


Auxiliary data on Astrometry: Considerations for the use of DR2 astrometry

Find auxiliary data provided by L. Lindegren along with his presentation "Considerations for the use of DR2 astrometry" here.


Auxiliary data on crossmatches

Find auxiliary data on Gaia DR2 crossmatch: Hipparcos2 here.


Overview of gaps in Gaia DR2 data

A description and overview of gaps in the data stream that underlies the Gaia DR2 data products can be found here.
