4.1.3 Performance Issues Under Study
The Calorimeter Assembly and Test program at NRL is well underway, and a very large set of calibration and functional test data has been collected on flight Modules FM101 through FM108. These data sets include a sequence of CPTs, LPTs, DAC calibrations, charge-injection calibrations, and muon calibrations, as well as specialized studies with the Modules in specific test configurations.
Routine analysis of the functional test and calibration data is performed by on-line scripts and off-line software (both in root and IDL). Inspection of the routine test reports and monitoring of the test and calibration runs have revealed some performance issues or idiosyncrasies that are now under ongoing study. These issues will suggest approaches to calibration and operation sequences for system testing and LAT mission operations.
The current version of the Issues list is captured in LAT-TD-05365
5 Unit Support Data
5.1 Telemetry Calibration Curves
Calibration curves shall be provided for
all telemetry. For telemetry that is
affected by temperature, calibration curves shall be provided over
temperature. For telemetry that is
affected by vacuum, calibration curves shall be provided from vacuum test. Calibration curves based on part# are acceptable
for thermistors.
5.2 Science Verification and Calibration
FM102 SVAC calibration was performed with calibGenCAL version v3r5.
