Constraint matrix factorization for space variant PSFs field restoration
F. M. Ngolè Mboula, J. -L. Starck, K. Okumura +2
Context: in large-scale spatial surveys, the Point Spread Function (PSF) varies across the instrument field of view (FOV). Local measurements of the PSFs are given by the isolated…
Super-resolution method using sparse regularization for point-spread function recovery
Fred Maurice Ngolè Mboula, Jean-Luc Starck, Samuel Ronayette +2
In large-scale spatial surveys, such as the forthcoming ESA Euclid mission, images may be undersampled due to the optical sensors sizes. Therefore, one may consider using a super-r…
Operations and Performance of the PACS Instrument 3He Sorption Cooler on board of the Herschel Space Observatory
Marc Sauvage, Koryo Okumura, Ulrich Klaas +5
A 3He sorption cooler produced the operational temperature of 285mK for the bolometer arrays of the Photodetector Array Camera and Spectrometer (PACS) instrument of the Herschel Sp…
The Herschel PACS photometer calibration - A time dependent flux calibration for the PACS chopped point-source photometry AOT mode
Markus Nielbock, Thomas Müller, Ulrich Klaas +7
We present a flux calibration scheme for the PACS chopped point-source photometry observing mode based on the photometry of five stellar standard sources. This mode was used for sc…
The effect of the high-pass filter data reduction technique on the Herschel PACS Photometer PSF and noise
P. Popesso, B. Magnelli, S. Buttiglione +36
We investigate the effect of the "high-pass filter" data reduction technique on the Herschel PACS PSF and noise of the PACS maps at the 70, 100 and 160 um bands and in medium and f…
CEA Bolometer Arrays: the First Year in Space
Nicolas Billot, M. Sauvage, L. Rodriguez +8
The CEA/LETI and CEA/SAp started the development of far-infrared filled bolometer arrays for space applications over a decade ago. The unique design of these detectors makes possib…
