Pushing Point spread function reconstruction to the next level. Application to SPHERE/ZIMPOL
Olivier Beltramo-Martin, Antonino Marasco, Thierry Fusco +4
Point spread function (PSF) reconstruction (PSF-R) is a well established technique to determine reliably and accurately the PSF from Adaptive Optics (AO) control loop data. We have…
Successful application of PSF-R techniques to the case of the globular cluster NGC6121 (M4)
D. Massari, A. Marasco, O. Beltramo-Martin +4
Precise photometric and astrometric measurements on astronomical images require an accurate knowledge of the Point Spread Function (PSF). When the PSF cannot be modelled directly f…
Towards an overall astrometric error budget with MICADO-MCAO
Gabriele Rodeghiero, Jörg Uwe Pott, Davide Massari +9
MICADO is the Multi-AO Imaging Camera for Deep Observations, and it will be one of the first light instruments of the Extremely Large Telescope (ELT). Doing high precision multi-ob…
The impact of ELT distortions and instabilities on future astrometric observations
Gabriele Rodeghiero, Jörg-Uwe Pott, Carmelo Arcidiacono +4
The paper discusses an assessment study about the impact of the distortions on the astrometric observations with the Extremely Large Telescope originated from the optics positionin…
