Estimating hyperparameters and instrument parameters in regularized inversion. Illustration for SPIRE/Herschel map making
F. Orieux, J. -F. Giovannelli, T. Rodet +1
We describe regularized methods for image reconstruction and focus on the question of hyperparameter and instrument parameter estimation, i.e. unsupervised and myopic problems. We…
Optical performance of the JWST MIRI flight model: characterization of the point spread function at high-resolution
P. Guillard, T. Rodet, S. Ronayette +16
The Mid Infra Red Instrument (MIRI) is one of the four instruments onboard the James Webb Space Telescope (JWST), providing imaging, coronagraphy and spectroscopy over the 5-28 mic…
Data inversion for over-resolved spectral imaging in astronomy
T. Rodet, F. Orieux, J. -F. Giovannelli +1
We present an original method for reconstructing a three-dimensional object having two spatial dimensions and one spectral dimension from data provided by the infrared slit spectro…
