Observations were made in three optical passbands (SDSS g', r', i'), and LCO's multi-site telescope network enabled the survey to achieve a typical cadence of ~10hrs in i' and ~15hrs in g' and r'. In addition, intervals of higher cadence (<1hr) data were obtained during monitoring of key microlensing events within the fields.
