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