HSRED Installation Guide
This page documents to installation procedures for the HSRED reduction package for IDL.  The installation assumes you already have a working distribution of IDL running on your account.  I have tested this software on IDL versions 5.6 and 6.0, as well as IDL student edition 5.6.  I have tried to make everything self consistent, but you have problems during installation, please let me know so that I can try and make the code work for everyone.  

The Basics:

The HSRED software if based heavily on the SDSS spectroscopic reduction pipeline and the code is dependent on the presence of these packages in your IDL_PATH.  If you already have a working version of IDLUTILS and IDLSPEC2D (version >= 5.0.0) running, then you can skip directly to the HSRED setup.  Otherwise, download the tarballs for these codes here:
          idlutils-v5_0_0.tar
          idlspec2d-v5_0_0.tar

    1. Unpack the tarballs (I will assume you are installing all of these packages to your home directory)
             % tar xvf idlutils*tar
             % tar xvf idlspec2d*tar

    2.  Setup the environment variables:
                a.   You need to have idl in your path and the IDL_PATH should be setup.  For me, I use the following in my .cshrc files
                              source /usr/local/rsi/idl/bin/idl_setup
                                    setenv IDL_PATH .:+{IDL_DIR}/lib

                b.    Now include the IDLSPEC2D and IDLUTILS variables in the path
                                  setenv IDLUTILS_DIR $HOME/idlutils-v5_0_0
                                    setenv IDLSPEC2D_DIR $HOME/idlspec2d-v5_0_0
                                    setenv PATH $IDLUTILS_DIR/bin:$IDLSPEC2D_DIR/bin:$PATH
                                    setenv IDL_PATH +$IDLUTILS_DIR/goddard/pro/:$IDL_PATH
                                    setenv IDL_PATH +$IDLUTILS_DIR/pro/:$IDL_PATH
                                    setenv IDL_PATH +$IDLSPEC2D_DIR/pro/:$IDL_PATH
                                   
     3. After you source your .cshrc file, you now need to compile to code
             % cd $IDLUTILS_DIR
             % evilmake all
             % cd $IDLSPEC2D_DIR
             % evilmake all

    4. IDLSPEC2D and IDLUTILS should now be ready to run.  If you have problems getting these up and running, you might want to take a look at the official reduction page for the packages - here.

HSRED SETUP:
Now you are ready to setup the HSRED package itself.  You can download the most recent incarnation here:
       hsred-current.tar.gz

It is also important that each user register with me, and not
                                      simply get the code from another user.  If you prefer,
                                      you can fill out this form to get immediate access to the data.
 
    1. Unpack HSRED
             % tar xvzf hsred*tar.gz
       
    2. Add HSRED environment variables to the .cshrc:
                 setenv HSRED_DIR $HOME/hsred  
                 setenv DUST_DIR $HSRED_DIR/dust
                 setenv IDL_PATH +$HSRED_DIR:$IDL_PATH

    3. HSRED should now be ready to run.  If you have problems with the HSRED reductions, please contact Richard Cool.
