Query: Isochrone fitting in the Gaia era. II. Distances, ages and masses from
  UniDAM using Gaia DR2 data   We present estimates of distances, ages and masses for over 3.5 million
stars. These estimates are derived from the combination of spectrophotometric
data and Gaia DR2 parallaxes. For that, we used the previously published
Unified tool to estimate Distances, Ages, and Masses (UniDAM).
