Commands

The main extensions to Tcl will be in the form of commands. Examples of telescope specific commands can be found at almost every observatory. The following list has been partly inspired by the OBSINP, OBS and OBSE adverbs in use at the Effelsberg 100m, Pico Veleta 30m and Mount Graham 10m telescopes.

All commands are executed immediately. There is no notion of an active or passive field which is then activated by the operator as in the case of OBS. Commands are executed synchronously and the calling program waits for a return from the control system before continuing.

1.
Low Level

Refers to commands used for low-level actions at a system level. These commands should normally only be used by system administrators.

2.
General

Refers to general commands which are useful for more than one type of observation.

3.
Steer

Refers to commands sent to the telescope drive program - STEER.

4.
Continuum

Commands which are used for doing continuum observations (ask Jonathan and George for input on this section).

5.
Spectral Line

Commands used for doing spectral line measurements (ask Mike for input on this section).

6.
Pulsar

Commands used for doing pulsar observations (ask Claire for input on this section).

7.
Mapping

Commands used for mapping (ask Justin for input on this section).
