Top: from left to right: ZELDA measurements (114 nm std), retrieved static map (140 nm) from the PSF-fitting and residual (70 nm std) in nm. This comparison emphasizes the meaningfulness of the PSF-fitting outputs, which compares very well with dedicated measurements of the LWE. Bottom: from left to right: on-sky DTTS image, best-fitted PSF, ZELDA-based PSF.
