8         Routine Calibrations

The SSC establishes and maintains the calibration of the IRAC instrument (see the Spitzer Observer’s Manual – Warm Mission).  Routine calibrations are executed by the SSC on behalf of the community.  Data resulting from routine facility calibrations generally enters the public domain immediately upon processing and validation by the SSC.


Observations of celestial targets necessary to establish and maintain the calibration of the AOT are not subject to rules regarding duplicate observations. The achieved calibration accuracy for AORs processed with the normal calibration pipelines is published as part of the Spitzer Observer’s Manual – Warm Mission.  For observations that require a higher level of calibration, and therefore special calibration observations (see §9), it is the responsibility of the requesting investigator to include those special calibration observations as part of their proposed observational program.
