Downloading and installation

• Right-click this link and select "Save link as":EWS.tar.gz
• Install according to these instructions

  
  To install the EWS system on your UNIX computer:
  
  1.  Define and create a root directory for the code and reference data.
      Specify this as an environmental variable drsRoot:
  
      mkdir /cool2/jaffe/ews
      setenv drsRoot /cool/jaffe/ews  (csh)
      export drsRoot=/cool/jaffe/ews  (sh)
  
  
      This assignment must be made whenever you want to use
      EWS, so it is most convenient to put it in a .login,
      .profile,.alias.... type file.
  
  2.  Copy the tar file  EWS.tar.gz into this directory
  
  3.  Extract the tar file. e.g.:
      tar -xf EWS.tar.gz --ungzip  (gnu tar sytax)
  
  4.  try gnu make:
  
      gmake install
  
  5.  cross your fingers.
  
  6.  In compiling the cfitsio library, the highest level 
      routine uses a script called configure to try to determine your
      local system parameters and set up a corresponding cfitsio/Makefile.
      If the diagnostic messages from the cfitsio compilations 
      look crazy, you have to edit the file $drsRoot/cfitsio/Makefile 
      and insert reasonable values there.  Look especially at
      the definition of CFLAGS in this file.
  
      After fixing cfitsio/Makefile, return to $drsRoot and type
      gmake install_c
  
      This should recompile the c-code using the new Makefile.
      If the make session ends with "mv: cannot stat `c/bin/disp*': No such file or directory
      ignore this, the mv was already executed in the previous run of gmake.
  
  7.  If the installation runs to completion, the following steps
      start things up:
  
      A.  Make sure drsRoot is assigned as above
      B.  assign the environment variable IDL_STARTUP
          to $drsRoot/EWS_STARTUP
  
          setenv IDL_STARTUP $drsRoot/EWS_STARTUP
  
          alternatively, add the code in this file to an
          existing IDL_STARTUP script.
  
          alternatively, AFTER STARTING IDL, type:
          @$drsRoot/EWS_STARTUP
  
      C.  Go to your favorite directory and type;
  
          idl
      
          Then type:
          @vltisetup
  
          Hundreds of compilation messages should flash by.
          You should now be ready to start, e.g:
  
          cd,'data_directory'
          files1 = midiGuiS()
          output_tag = '/mydisk/reduced_data/source1'
          midipipe,output_tag,files=filesq
  
  8.   There are much more detailed descriptions of the EWS
       routines in the UserGuide in the $drsRoot/export directory
