To all who have requested a Sparc version of 'FITS2':

We have ported FITS2 (with some improvements) to the Sparc using the
publicly available plotting package PGPLOT.  We have gotten the program to
work (quite nicely) in an xterm window; we are still trying to figure out
gterm and various tek4014 options (cursor problems).  We have put the
various 'fits6p' subroutine source files into a compressed tar file for
anonymous ftp, and have appended to this message instructions for
obtaining PGPLOT.  Please let us know if you use fits6p, so that any
future enhancements can be passed along; also let us know of any questions,
problems, suggestions, etc.  We hope it proves useful to you.

Note on the entries in atomic.dat: this file contains wavelengths,
oscillator strengths, and damping constants from various sources
(including some wild guesses for the damping constants for some lines)
so be sure to check that your "favorite" lines have the oscillator
strength of your choice.  This file is easily edited so this is no
big problem.

How to install:

1] Install pgplot -- the pgplot home page is:

	http://astro.caltech.edu/~tjp/pgplot/

This version of fits6p has been compiled with versions 4.9h and 5.2.0, and presumably
works with other versions.  I recommend downloading version 5.2.0, you can do this via
your browser using the URL:

	ftp://astro.caltech.edu/pub/pgplot/pgplot5.2.tar.gz

or via anonymous ftp:

	ftp astro.caltech.edu
	login name = anonymous
	password = your e-mail address
	binary
	cd pub/pgplot
	get pgplot5.2.tar.gz

Now you have to gunzip and extract the source from the tar file:

        gunzip -c pgplot5.2.tar.gz | tar -xvf -

This will create directory pgplot (and subdirectories) in the current
directory.

Follow the installation instructions and install.

(Thanks to Tim Pearson, Astronomy Dept 105-24, Caltech,
Pasadena, California 91125, USA for support of pgplot).

2] Change your .cshrc to reflect the location of the fonts used
by pgplot.  For example on oddjob this is done by the entry:

setenv PGPLOT_FONT /usr/local/lib/pgfonts/grfont.dat

You should alter the path to reflect the path of the pgfonts directory
[note that any setenv lines should appear after the line that sets the
path (set path = .....) and history, etc. and before any aliases].

3] Get the fits6p code by anonymous ftp as a compressed tar file
(be sure to use binary mode).

Make a directory for fits6p:

	mkdir fits6p
	cd fits6p

Use anonymous ftp (user: anonymous, password: your id
[username@machine]) to node astro.uchicago.edu (128.135.70.30).
Issue the following ftp commands to retrieve the gzipped tar file:
 
        binary  
	cd pub/astro/welty/F6P
        get fits.tar.gz
 
Decompress and extract the source from the file:
 
        gunzip -c fits.tar.gz | tar -xvf -
 
This will extract the fits6p code and Makefile in the current
directory.

4] Edit the files fitsio.F and fitcon.F to reflect the location
of the files atomic.dat and dawson.dat, The present entries begin with:

	/home/boromir/welty/DATA/

5] In the fits6p directory type:

	make fits6p

You will see lots of messages from the fortran compiler.

6] move the binary fits6p to the desired directory.

7] make clean (cleans up files).

***************************************************************************

Known Bugs ("Features"):

1) the fitsio is a total kludge at this point, with the multispec fits file
	being the worst of the bunch...alpha implementation (ie. totally
	broken) of the FITSIO subroutine.

2) the "zoom" feature added to the fitting analysis has been removed temporarily
	due to some proplems with the cursor positioning.

Planned updates:

1) fix fitsio (especially binary table nonsense).

2) fix zoom.

3) finish GUI interface using ptcl.

4) integrate Welty code for simultaneous fitting of multiple lines.
