The Variability Processing and Analysis Coordination Unit (CU7) and its associated
Data Processing Centre in Geneva (DPCG) gather about 60 people, spread in 18
institutes mostly in Europe (in addition there are contributions of Tel Aviv
University, Israel and of Villanova University, USA). The approach to the successive
data releases is iterative.
In this second data release we make a significant jump from the first data release: in
Gaia DR1, we released 3194 Cepheid and RR Lyrae star candidates and in Gaia DR2 we
reach more than 550 000 stars, with 6 variability types. We classified also eclipsing
binaries and QSOs that were passed to other coordination units to be analysed and
published in Gaia DR3.
