Software Overview

Observing with the Hamilton Spectrograph requires a suite of programs that operate in concert, but are addressed through several GUIs, separated by function as follows:

Summary of Observing Software for the Hamilton Spectrograph
ProgramFunctionComputer: Command1
Data-Taker Control CCD array and set exposure parameters.
ssh user@dusty ham_coude_start 

	or

ssh user@dusty ham__cat_start

For the Shane or CAT telescopes, respectively.
	
Hamilton Motor Controller Control Hamilton motorized stages: aperture plate, filter wheel, CCD focus, grating tilt, height, guider filter wheel, guider focus, guider zoom, arc and flat lamps, and iodine cell.

1If no computer is specified, command is available and the same on every user computer.

Your observing needs and which telescope you are working at will determine which of the above pieces of software you will need for observing. Only the Data-Taker and the Hamilton Controller are required for all Hamilton Spectrograph Observers.
