IR multicolour information
From VVV Survey
Goal 8: To provide complementary IR multi-colour information
(for reddening, temperatures, luminosities) and time coverage to the following past and on-going surveys: GLIMPSE-II and VST PHAS Hα survey (both limited to the Galactic plane), MACHO, OGLE, EROS, MOA, and PLANET. Near-IR photometry is important for the microlensing events discovered by these microlensing surveys. For old events or new ones, our VVV survey will give field reddening and a baseline colour and magnitude that can immediately be translated to temperature and luminosity for the source star. The characterization of the source is essential for refining the microlensing light curve parameters and the lens physical properties .
