Table J.2 contains a brief summary of the IRAC2 commands and parameters. All commands are initialized by enabling the IRAC2 context with the MIDAS command SET/CONTEXT IRAC2. The CCDRED context is also made available when the IRAC2 context is initialized. Consult Chapter 3for details of the CCDRED context.
