High-cadence Euclid observations made simultaneously with WFIRST could measure microlens parallax and mass for about twenty free-floating planets over 120 days of coordinated observing.

abstract
NASA's WFIRST mission will perform a wide-field, NIR survey of the Galactic Bulge to search for exoplanets via the microlensing techniques. As the mission is due to launch in the mid-2020s, around half-way through the LSST Main Survey, we have a unique opportunity to explore synergistic science from two landmark programs. LSST can survey the entire footprint of the WFIRST microlensing survey in a single Deep Drilling Field. Here we explore the great scientific potential of this proposal and recommend the most effective observing strategies.

WFIRST and EUCLID: enabling the microlensing parallax measurement from space
High-cadence Euclid observations made simultaneously with WFIRST could measure microlens parallax and mass for about twenty free-floating planets over 120 days of coordinated observing.
