* Monitor the SSR fill level. If the memory is not emptying after the daily pass set, steps may need to be taken to reduce the fill level, including changing the decimation state, changing the collection of nighttime data, or changing detector parameters if one detector is causing the high fill.  In rare cases of extremely high activity, data could be deleted by moving the SSR pointers.  Please try to avoid deleting day-before and day-after intervals used for gamma-ray background corrections if this becomes necessary.

Duties

The job of the tohban is to help the spacecraft operators at the the Mission Operation Center (MOC), located in the north end of the second floor of the SSL Addition Building, to optimize the science quality of the observations, and maintain the working order of RHESSI's scientific instruments. Tasks include the following.
