Euclid Data Release 1 (DR1) - NISP-P point-spread function modelling pipelines
Abstract
The images collected in photometric mode by the Near-Infrared Spectrometer and Photometer (NISP) instrument of the Euclid satellite are used to model the point-spread function (PSF) of a selection of sources detected in single and combined frames. We used Q1 and DR1 data to improve the development of the PSF module of the near-infrared processing function (NIR PF) and to refine the models currently provided. We explored a few methods normally used to evaluate the quality of the derived models and discuss possible variations related to the position of the sources in the focal plane and to the wavelength and time of the observations. The procedure of fitting the PSF profile, compared to other methods used for flux estimation, such as aperture photometry, indicates that updated models are better than those provided by Q1 images. The current results are in agreement with several key requirements defined for the mission, but there is still room for further improvements, which we plan to investigate and implement in future releases.
