Abstract
The Ph.D. project described in this work is based on two main activities. The first one is the analysis of Jupiter flux time-lines aimed at the intercalibration between the Planck and WMAP mission, to properly calibrate the beam pattern and to study Jupiter atmosphere. The second is the implementation of a prototype end-to-end simulator, using the Euclid mission as a test case, designed to assess mission performance and support instrument operations. The spectral energy distribution (SED) at millimetric wavelengths of planets is an important benchmark to inter-calibrate different CMB experiments, to properly calibrate the beam pattern and it is a source of information on the atmospheric structure of those bodies. Despite their importance, there is a lack of very accurate measures of SED for those bodies. Planck observed Mars, Jupiter, Saturn, Uranus and Neptune from three to eight times during the mission. In particular, Planck furnished a good measurement of the brightness temperature for Jupiter, with an accuracy better than half a percent. Jupiter flux analysis not only improved the SED results previously quoted in literature, but was also part of the Planck/LFI pipeline, due to its importance for the detector beam reconstruction and for the inter-calibration between Planck itself and its predecessor WMAP. The analysis represents also an important test bench for the second part of this Ph.D. project, aimed at developing an End-to-End simulator for the Euclid mission. End-to-End mission performance Simulators (E2ES) enable the generation of simulated output data for selected test scenarios to support the assessment of the mission performance. I have been involved in the design of a reference architecture of an E2ES aimed at supporting instrument operations and in the development of a prototype, providing basic functionalities. The Euclid Mission has been selected as test case.File | Dimensione | Formato | |
