The empirical <i>Gaia G</i>-band extinction coefficient
The empirical <i>Gaia G</i>-band extinction coefficient
Context. The first Gaia data release unlocked the access to photometric information for 1.1 billion sources in the G -band. Yet, given the high level of degeneracy between extinction and spectral energy distribution for large passbands such as the Gaia G -band, a correction for the interstellar reddening is needed …
