Installation of the PySALT external package V0.4 ---------------------------------------------- [0] This package requires IRAF version 2.12.2 or later, Pyraf version 1.7 or later and the PyQt4 GUI toolkit. [1] The package is distributed via the SALT web pages, see http://www.salt.ac.za The README file contains these instructions. [2] To install the package as root, create a directory to contain the PySALT external package files. This directory should be outside the IRAF directory tree and must be owned by the IRAF account. In the following example, this root directory is named /iraf/extern/pysalt/ (UNIX and Linux). Make the appropriate file name substitutions for your site. [a] Log in as IRAF and edit the extern.pkg file in the hlib directory to define the package to the CL. From the IRAF account, outside the CL, you can move to this directory with the commands: % cd /iraf/iraf/unix/hlib/ Define the environment variable salt to be the pathname to the salt root directory. UNIX pathnames must be terminated with a '/'. Edit extern.pkg to include: reset pysalt = /iraf/extern/pysalt/ task pysalt.pkg = pysalt$pysalt.cl Near the end of the hlib$extern.pkg file, update the definition of helpdb so it includes the salt help database, copying the syntax already used in the string. Add this line before the line containing a closing quote: ,pysalt$lib/helpdb.mip\ [b] Change directories to the PySALT root directory created above and unpack the download file pysalt.tar.gz % cd /iraf/extern/pysalt/ % tar zxvf /pysalt.tar.gz where is the relative path from /iraf/extern/pysalt to the downloaded file. [4] To install the package under your home directory, unpack the downloaded file pysalt.tar.gz. Then add the following line to your loginuser.cl: reset pysalt = "[your path]" task pysalt.pkg = "pysalt$pysalt.cl" reset helpdb = (envget("helpdb") // ",pysalt$lib/helpdb.mip") [5] Please use the SALT help desk for submitting questions: salthelp@salt.ac.za
