What is XOP?
============
XOP (X-ray Oriented Programs) is a graphical user interface to
run computer programs that calculate basic information needed by
synchrotron radiation beamline scientists and engineers. It can also be
used as a front end for specific codes or packages for data analysis and 
data reduction.
XOP contains a customized database for optical and atomic constants (DABAX).
It has a flexible design and new applications may be added.

XOP extensions:
===============

The available XOP extensions included are:

	and for Unix (Sun,HP,Alpha and Linux).
	Version: SHADOWVUI 1.0 Beta 3

XAID: XAFS is a package to perform XAFS data analysis. 
	Available under Windows and under all 
	supported Unix platforms.
	Version: XAID 1.2

PROW:  A data integration program based on profile fitting for the 
	evaluation of weak and/or overlapped 2-dimensional macromolecular 
	diffraction patterns written by Dominique Bourgeois (bourgeoi@esrf.fr)
	Available only under Unix (HP,Sun,Linux,Silicon Graphics,Compact
	Alpha)
	Version: PROW 1.3

IMD: IMD is an that can calculate the optical properties - reflectance, 
	transmittance, and absorptance - of an arbitrary multilayer structure.
	It has been written by David L. Windt (windt@astro.columbia.edu).
	Available under Windows and under all 
	supported Unix platforms.
	Version: IMD 4.1

TOPO: TOPO is a program to perform analysis on profiles and surfaces.
	It has been written by David L. Windt (windt@astro.columbia.edu).
	Available under Windows and under all supported Unix platforms.
	Version: TOPO 2.04


Licensing information:
======================

The XOP software is built using an embedded license of IDL from 
RSI (Research Systems Inc.) (http://www.rsinc.com) under the conditions 
of the "XOP embedded software license agreement" signed by RSI, ESRF and
APS. This implies that the user is allowed to run the XOP software but
not to separate, modify or transform in any way parts of the IDL software 
included in XOP. Additional information can be obtained by srio@esrf.fr

See the file $XOP_HOME/XOP2.0/README_COPYRIGHT.TXT in the 
main XOP directory after installation.


Registration:
=============

You can use XOP without registration. However we encorage you to
register because of two important reasons. 
  1) It allows us to contact the users for informing on new releases and
	important bugs.
  2) It allows us to know to know the number of users and its
	distribution around the world. This is important to help us to
	demostrate to our bosses how useful is XOP and to obtain more
	support to guarantee the continuity of the XOP project

On-line registration can be done at:
	http://www.esrf.fr/computing/scientific/xop/xopreg.html

Mailing list:
=============

A useful mechanism to be updated on XOP and exchange information 
on it is to subscribe the XOP mailing list. For that send an email to
	           xop-users-request@esrf.fr
with only the work "subscribe" in the text area (not in the subject area!).
The emails to the list are archived at:
	http://www.esrf.fr/computing/scientific/xop/xop-users
