ATLAS covers sky to 19.5 at 5 sigma. That's an uncertainty of 20% or 0.2 mag. The all-sky, nightly coverage from multiple sites makes this an excellent resource for microlensing.
Microlensing surveys:
OGLE, Las Campanas in Chile, has been shut down for years due to COVID
MOA in New Zealand
KMTNET has telescopes in Chile, South Africa, Australia.
Web sites with microlensing events (note the anomalous ones are arguably the most interesting)

KMT-2022-BLG-0061, difference request
JT says 2022 observations from Chile aren't in the forced photometry data, and that the Hawaii telescope stayed in the N after early calendar 2022. So need to look back into previous years.
ATLAS started operation mid-2015, so it's appropriate to compile a list of events from calendar 2015 to 2022. That spans both OGLE (until 2020) and MOA, not sure about KMT.
MOA to OGLE correspondences: https://www.massey.ac.nz/~iabond/moa/alert2016/moa2ogle.php
MKTnet telescopes go fainter. Use their event catalogs from online data set.
text file columns:
name, DiscoveryField, Class(1=clear, 2=probable), RA, DEC, MJDcenter, duration (days), impact parameter ~ 1/Amplification, Iband1, Iband2, Iband3, Ctype (??), Amplification, other names
Tasks:
1) construct aggregated event list that spans years when ATLAS observed Galactic plane. DONE- had to clean up changes in data format between years, for KMT alert files, and delete a few incomplete records. KMTevents.txt has around 15,000 
candidate bulge events.
2) for each event, do a query on forced photometry difference photometry for duration spanning 10 event duration times on either side of event center.
3) construct database of event photometry.
