The thin and medium filters of the EPIC camera on-board XMM-Newton: measured performance after more than 15 years of operation
Tiengo, Andrea; Barbera, Marco; Gastaldello, Fabio +9 more
After more than 15 years of operation of the EPIC camera on board the XMM-Newton X-ray observatory, we have reviewed the status of its Thin and Medium filters. We have selected a set of Thin and Medium back-up filters among those still available in the EPIC consortium and have started a program to investigate their status by different laboratory m…
The Footprint Database and Web Services of the Herschel Space Observatory
Valtchanov, Ivan; Budavári, Tamás; Verdugo, Eva +5 more
Data from the Herschel Space Observatory is freely available to the public but no uniformly processed catalogue of the observations has been published so far. To date, the Herschel Science Archive does not contain the exact sky coverage (footprint) of individual observations and supports search for measurements based on bounding circles only. Draw…
Building the analytical response in frequency domain of AC biased bolometers. Application to Planck/HFI
Montier, Ludovic; Sauvé, Alexandre
Context: Bolometers are high sensitivity detector commonly used in Infrared astronomy. The HFI instrument of the Planck satellite makes extensive use of them, but after the satellite launch two electronic related problems revealed critical. First an unexpected excess response of detectors at low optical excitation frequency for ν < 1 Hz, and se…
