      Description

      In DM-17429 we discuss the use of Lanczos5 kernels to improve the PSF interpolation on coadds, but we also found that Lanczos7 kernels had worse behaviour.

      Investigate interpolation in single visit and coadds, getting to the bottom of exactly what is going on, and propose a fix.
