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.
These sources are shifted using cubic interpolation to the center of the PSF stamp and coded to produce the sub-image PSF
