The Schedblock entity is the fundamental, "atomic" (in the sense that it may be aborted, but not restarted in the middle) observing unit for ALMA. It will usually consist of a set of target definitions (field source + pattern, instrument setup and observing parameters) and logic to control their execution. It is essentially a "quantum" of observing.
SchedBlock is an entity class.
