* Note that all FSI modes will typically be combined with the Beacon mode (B) defined above to assure regular EUI LL data. The data rates above do not yet include this extra TM, total data rate is given in the mode-specific pages (see e.g. FSI Synoptic mode (S)).
** Some more specific FSI modes will have both Beacon mode (B) and Synoptic mode (S) running in parallel. The data rates above do not yet include this extra TM, total data rate is given in the mode-specific pages (see e.g. FSI Global eruptive event mode (G)).
*** Maximum time for this mode to run per orbit is based on the average EID-A rate over the 30 days RSwindows. There will be times though that more downlink is available, and at other times more stringent restrictions will apply.
