| Command: | etype |
| Contexts: | Network socket, serial console, stage2 only |
| Function: | Request exposure type setting applicable to next "expose" command |
| Required Parameters: | Either object or bias or dark (or letter o,b,d) |
Usage
This command sets a "sticky" parameter. It doesn't do anything to the detector, but it sets the exposure type to be performed during the next expose command. It only needs to be sent to the controller upon initialization, or when the type changes, though there is no harm sending it before every exposure.
etype bias
Requests that next expose will be a BIAS calibration type. Integration time will be ignore and detector read immediately (presumably right after issuing clean.)
etype dark
Requests that next expose will be a DARK calibration type. Integration timer is used, but the shutter does not open. Integration period must be set with etime.
etype object
Requests that next expose will be an OBJECT (science frame) type. Shutter is opened for the requested integration period. Integration period must be set with etime.
