ToO and TOO are both used - add both to the glossary, point on to the other

AMPEL page is not very brokery ..

All brokers listed

mini-survey: A portions of the sky that will be observed with a different cadence to the main survey, but not necessarily to a greater depth, to address science goals beyond the scope of the main survey, e.g the Galactic Plane, Ecliptic, or South Pole. They are different to Deep Drilling Fields (DDFs) in that Deep Drilling Fields are single pointings.

micro-survey: Mini-surveys whose use of observing time is up to 3% of LSST survey time for
regions outside of the baseline footprint. Examples include ToO follow-up to ID counterparts to GW sources, or short twilight visits for near-Sun objects incl. NEOs.

Note the Survey Cadence Optimization Committee’s Phase 1 Recommendation uses ToO for target of opportunity
