There are three ranges for the germanium detectors: 2 Mev, 5
MeV and 20 MeV. When the 2, 5 or 20 MeV red buttons are pushed the
appropriate range FOR THE SELECTED DETECTORS are set. Thus, to set all
detectors to the 5 MeV range, specify '1-110' as the selected detectors
and push the 5 MeV button. The EFF section has no effect in this case
since the range is controlled in the VXI ge/bgo boards.
For the temperature alarms to function properly,
the alarm limits for the germanium temperatures must be set. By pushing
the "set alarm limits: button, the current high and lower alarm limits
for normal temperature excursions are set to +10 and -10 degrees
around the current temperature. The so called HIHI and and LOLO limits
are set to +15 and -15, respectively, as well. Only the detectors
on the detector list have their alarm limits modified.

A Doppler correction can be imposed on the
calibration parameters that were found using sources. This is done by
specifying a 'v/c' value (e.g, 0.0158 would be 1.58% of the speed of
light) and pushing the Doppler correct button. It is probably a good
idea to save the 'source' calibration parameters before you do this.
Care must be taken not to push this button more than once. There is not
at present any check on whether the current calibration parameters in
the EFFs are Doppler corrected or not. The gecal2 Tcl/Tk script
contains tools to find the correct v/c for the doppler correction.
