Low-Cadence Seasons
The exoplanet census, via microlensing
What this is
Four seasons at a slower revisit, obtaining 30 photometry and 30 grism snapshots per season. Extends the baseline for long-duration events and characterises the field.
Six fields toward the Galactic centre, imaged every twelve minutes for weeks at a time. Microlensing events are brief and unrepeatable — the cadence is the experiment.
