Issue Date: | 2009 | Number: | PL-LFI-PST-RP-061 | Abstract: | Spurious frequency spikes at the fundamental frequency of 1 Hz are known to be present in the LFI scientific data caused by an anomalous interaction between the DAE housekeeping sequencer and the scientific channels. The effect is a spurious signal that adds to the radiometric output after detection and is characterized by frequency spikes at the fundamental frequency of 1 Hz. These spikes are characterized by a series of tests run during all the test campaign in order to check this effect in different situations. Tests performed on ground at satellite level have shown that the effect of these spikes on the LFI science is expected to be very small; therefore the main objectives of the same tests performed during CPV is to compare results with those obtained during the CSL test campaign. | Note: | Planck LFI Commissioning and Performance Verification (CPV) | URI: | http://hdl.handle.net/20.500.12386/33255 | Fulltext: | open |
