Issue Date: | 2012 | Number: | PL-LFI-PST-TN-107 | Abstract: | We propose to extend the Planck mission in “LFI-only” mode until 13 August 2013, which will permit the completion of an 8th full-sky survey for all LFI detectors. This extension is made possible by the predicted lifetime of the 20K sorption cooler now in operation, which far exceeds previous projections. The additional observations will lead to a significant improvement in the control of systematic effects and calibration accuracy through a set of new powerful null tests probing the 6-months, 1-year, and 2-years time scales. The current status of the Planck data analysis indicates that such improvement may be very important for a full extraction of Planck cosmological science at low multipoles, especially for polarisation. We also note that the LFI may be the last instrument delivering full-sky temperature maps in its frequency range in a very long time, adding to its legacy value. | URI: | http://hdl.handle.net/20.500.12386/34874 | Fulltext: | open |
