Point spread function wavefront recovery from in-focus stellar observations
Ezequiel Centofanti, Samuel Farrens, Jean-Luc Starck +1
Recovering the wavefront error (WFE) field of an optical system from intensity in-focus observations is a challenging inverse problem with broad implications for telescope point sp…

Breaking the degeneracy in stellar spectral classification from single wide-band images
Ezequiel Centofanti, Samuel Farrens, Jean-Luc Starck +3
The spectral energy distribution (SED) of observed stars in wide-field images is crucial for chromatic point spread function (PSF) modelling methods, which use unresolved stars as…
