HRC Command Sequences

Disable Center-Blank

Description:

The center-blanking function of the HRC allows the science team to select rectangular regions of the x-ray detector from which the events will not be processed by the on-board electronics and consequently will not be put into the telemetry stream. This command sequence disables the center-blanking function and resets the bounds of the rectangular region to their default values.

Cautions/Restrictions:

None
