Vera Rubin / LSST is going to image the sky so many times (hundreds of visits to each part of the sky) that small chip gaps in individual images won't matter in

Vera Rubin / LSST is going to image the sky so many times (hundreds of visits to each part of the sky) that small chip gaps in individual images won't matter in the end. The survey strategy is driven by completely different concerns, such as detection efficiency for asteroids or supernovae. Cosmetic issues like chip gaps are not a major concern.
