ARCPLOTS is an IDL6.0 routine written as a planning tool for 
spectroscopic observations. ARCPLOTS is also useful at the 
telescope when a quick line identification is desired. ARCPLOTS
is available at the Keck Observatory for general use. This 
readme describes how to run ARCPlOTS on your local machine.

ON UNIX or LINUX machines:

If the local machine has IDL6.0 installed
	1) start an IDL session

	2) Restore the contents of the save file
		IDL> restore, 'arcplots.sav'
	3) Run arcplots 
		IDL> arcplots
		
     	

If IDL is currently unavailable
	1) Down load and install the IDL Virtual Machine from 
		the IDL Virtual Machine home page.
		The software is free to the public.

	3) When prompted, load the 'arcplots.sav' file
		to run ARCPLOTS
