calibration data where the accumulated value for each pixel
replaces the factory offset corrected pixel value. The data is
collected for the currently selected OPR and timing mode. Once
accumulated, this data will then start to be used to apply offset
correction to the pixel data for the OPR that was used when it was
collected.
It is intended for the user to inhibit light from falling on the FPA for
the duration of the command execution: For normal OPR
operations, 32 frames at 30 fps is roughly 1 second.
64
Initiates an averaging of 64 frames of field offset
calibration data where the accumulated value for each pixel
replaces the factory offset corrected pixel value. The data is
collected for the currently selected OPR and timing mode. Once
accumulated, this data will then start to be used to apply offset
correction to the pixel data for the OPR that was used when it was
collected.
It is intended for the user to inhibit light from falling on the FPA for
the duration of the command execution: For normal OPR
operations, 64 frames at 30 fps is roughly 2 seconds.
FLASH Optional. If FLASH is not specified, the camera
accumulates and stores the offset data in camera memory for use in
the current OPR. The data is held until power is cycled/reboot. The
new offset correction will be available if you leave and return to the
given OPR.
If FLASH is specified, on completion of the frame collections, the
camera will then write the new correction data to camera flash
(nonvolatile) memory, which survives camera reboots.
OUTPUT
Provides a countdown of the flash write activity,
parsed at reasonable intervals. While possibly helpful in monitoring
the flash write process, OUTPUT does not time the actual
acquisition of frames. Typical time for FLASH operations to
complete can be as long as 4 seconds. The OUTPUT command use
does not change the operation length of the FLASH update.
Invoking OUTPUT without FLASH adds no value.

Example
CORR:OFFSET:CAL 32 FLASH OUTPUT
-- acquire cal offset data based on 32 frames and write to camera
nonvolatile memory while metering the flash write process.
CORR:OFFSET:CAL 64
-- acquire cal offset data based on 64 frames and save in camera
live (volatile) memory.
