Operational forecast of the PSF figures of merit
A. Turchi, G. Agapito, E. Masciadri +6
The optimization and scheduling of scientific observations done with instrumentation supported by adaptive optics could greatly benefit from the forecast of PSF figures of merit (F…
Joint estimation of atmospheric and instrumental defects using a parsimonious point spread function model.On-sky validation using state of the art worldwide adaptive-optics assisted instruments
Olivier Beltramo-Martin, Romain Fétick, Benoit Neichel +1
Modeling the optical point spread function (PSF) is particularly challenging for adaptive optics (AO)-assisted observations owing to the its complex shape and spatial variations. W…
Reconstruction of the ground-layer adaptive-optics point spread function for MUSE Wide Field Mode observations
Thierry Fusco, R. Bacon, S. Kamann +7
Here we describe a simple, efficient, and most importantly fully operational point-spread-function(PSF)-reconstruction approach for laser-assisted ground layer adaptive optics (GLA…
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…
