XSTAR as Part of the FTOOLS Package

Instructions for installation of the heasoft package are available elsewhere

 
http://heasarc.gsfc.nasa.gov/lheasoft

On a system where heasoft is already installed it is necessary to run the same script required for other ftools in order to make sure environment variables are set properly for xstar:

setenv HEADAS /path-to-architecture
source $HEADAS/headas-init.csh

where 'path-to-architecture' is the full path to the directory containing the compiled executables and libraries for the headas software.
