Next: Bias Telemetry Choices Up: 3.1.3 On-board Data Processing Previous: `Smear' Exposure Times Diagnostic

Several diagnostic modes are available for monitoring instrument performance or collecting more detailed information than normally available. These modes are highly consumptive of telemetry capacity and so should not be used in most normal operation.

Raw: The raw, unprocessed CCD pixel and overclock data are telemetered to the ground.

Raw Histogram: A histogram of the number of CCD pixels vs. data number value is telemetered, accompanied by overclock pixel average and variance, without any attempt at X-ray event energy reconstruction.
