SS2 data have been already range-processed on board and thus they can be readily used in their original form, found in the Level 1b archive. The user is warned, however, that on-board processing for SS2 produces data of low quality that should not be used. The format of the various SSx modes is very different. There are 45 observations acquired in mode SS1, 44 in mode SS4 and 3 in mode SS5, and they all belong to the early part of the science phase. As of today, there are 7698 observations acquired in mode SS3. For all these reasons, a standard processing chain producing Level 2 SS1, SS4 and SS5 data has been given a lower priority, although it will eventually be implemented to complete the archive. Update history: =============== Date Change ---------- ------------------------------------------------------------------ 2016-10-01 Errata written to warn of missing data for modes SS1, SS4 and SS5
