LAST pipeline achieves 80% single-epoch transient detection efficiency and over 90% purity at 7.5 sigma using ZOGY subtraction combined with Translient statistic and deterministic filters, reaching 20.3-20.7 mag limit on commissioning data.
In the near future, steps 10 to 16 will be replaced with a multi-iteration matched filtering and PSF subtraction including the PSF, a delta function, and an extended PSF
