Subsystem

TMT Observatory system is composed of many subsystems. The subsystems that are known participants in the TMT Software System are predefined and the list is covered under the Subsystem enumeration. They are identified using an abbreviation typically of 3 or 4 letters.

Susbsystem values are used to construct Source and are used in communication vehicles such as Commands, Events and States.
