Installation Instructions for the KECK Package

The KECK package contains a hodge-podge of IRAF tasks for use by the
various instruments of the W. M. Keck Observatory.  The current
maintainer of the package is Gregory Wirth ([email protected])

These instructions describe how to install KECK either as a user
package or as a layered (external) package to IRAF.  A user package
can be installed by any user, and is only available to users if their
"loginuser.cl" files contain the necessary additions.  A layered
package is layered on as part of IRAF and is available to all IRAF
users without any changes to their "loginuser.cl" file.  A layered
package can only be installed by the IRAF user.  Documentation on
layered software is found in the Site Manager's Guide that accompanied
your IRAF distribution.

[1] The package is distributed as GNU compressed tar file.  Retrieve
the file from this URL:

  ftp://ftp.keck.hawaii.edu/outgoing/ObservingTools/iraf/keck.tar.gz

[2] Create a directory to contain the KECK external package files.  This
    directory should be outside the IRAF directory tree.  If KECK is being
    installed as a layered package, then the directory must be owned
    by the IRAF account.  In the following examples, this root directory
    is named /local/keck/ (UNIX).  Make the appropriate file name
    substitutions for your site.

[3] If KECK is being installed as a user package, then this step can be
    skipped.  If KECK is being installed as a layered package, then the
    IRAF system must be made aware of its existence by adding it to the list
    of external packages.  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 $hlib

    Define the environment variable keck to be the pathname to the keck
    root directory.  UNIX pathnames must be terminated with a '/'.
    Edit extern.pkg to include:

	reset keck     = /local/keck/

	task  $keck.pkg = keck$keck.cl

[4] Unpack the archive file.  From the shell, change directories to
    the KECK root directory created above and use 'gtar' if available:

	gtar xvzf keck.tar.gz

    of do this as separate steps via:

	gunzip keck.tar.gz
	tar xvf keck.tar
	
    The archive file can be deleted once the package has been
    successfully installed.

[5] The compiled parts of the KECK package will only build properly
    under Solaris.  The compilation and linking of the KECK package is
    done using the following command:

	cl> mkpkg update >& spool &

    The spool file(s) should be reviewed upon completion to make sure there
    were no errors.  

    NOTE FOR USER PACKAGE: If someone other than the IRAF account is compiling
    the package (i.e., if KECK is being installed as a user package) then
    certain enviroment variables must be set.  In Unix, before entering CL,
    type the following:

	# Substitute the appropriate path to the IRAF root directory below
	% setenv iraf /local/iraf/
	% source $iraf/unix/hlib/irafuser.csh

    On a Sun, the architecture must also be specified.

	# Substitute f68881 or ffpa for sparc below if necessary
   	%setenv IRAFARCH sparc

[6] If KECK was installed as a layered package then this step can be skipped.
    If it was installed as a users package, then each user wanting access to
    the package needs to put the following lines into his/her "loginuser.cl"
    file, somewhere before the "keep" command.

	reset	keck		= /local/keck/
	task	keck.pkg	= keck$keck.cl
