ChangeLog for ekstest
===============================

Open SPRs:

Version 2.1 -  2005-04-19 (NW)
----------------------------

        Updated the documentation to make it clear that no variability
 	tests are carried out if there are insufficient good bins.
		
Version 2.0 -  2004-11-26 (NW)
----------------------------

	Added several new variability tests (flare and variation tests)
	along with parameters to control these tests.  The chi-squared
	test has been modified by S. Mateos.  The documentation has been
	rewritten.

Version 1.3.6 -  2004-09-03 (NW)
----------------------------

	Small code change so that ekstest deals with the NULLS in the same
	way as elcplot (version 1.2.6).

Version 1.3.5 -  2004-08-13 (NW)
----------------------------

        Small code change - now keeps background counts = 0.0 as well.

Version 1.3.4 -  2004-08-10 (NW)
----------------------------

	Added missing line necessary to stop the new header information
	being written into the given input file (only written to a new
	file).  Also changed error calculation for the total counts, when
	they are recovered from the net and background counts.

Version 1.3.3 -  2004-08-09 (NW)
----------------------------

	This version makes sure that ONLY the NULL values are taken out
	and not the 0.0 values as well.  Ekstest also tests to make sure
	that total counts are not negative (whatever the nature of the
	input file) and also raises an error if no screen output is
	requested and nor is a new output file specified.  The
	documentation has also been updated.
	

Version 1.3.2 -  2004-08-02 (NW)
----------------------------

	This version now keeps all negative net counts.  


Version 1.3.1 -  2004-07-27 (NW)
----------------------------

        The kolmogorov-smirnov test code has been revised (now based on
	numerical recipes code) and a new boolean parameter (twodists) has
	been introduced so that the user can choose to carry out a two
	distribution KS-test (counts verses background) or a single
	distribution KS-test (net counts).  Some warnings have been
	revised.  The documentation has been updated.
	

Version 1.3 -  2004-07-01 (NW)
----------------------------

	- Ekstest can now write a new file (with the results contained in
	the header of the new file rather than the original file) and/or
	write the results to the screen. The documentation has also been
	updated.

Version 1.2 -  2004-06-14 (NW)
----------------------------

	- Updated DEPEND file so that ekstest builds correctly.

Version 1.1 -  2004-05-28 (NW)
----------------------------

	- Made the GTI file parameter an optional one as well as checking
	whether the input file contains the background subtracted
	lightcurve or the unsubtracted lightcurve.  If it is background
	subtracted ekstest calculates the unsubtracted lightcurve (and the
	associated errors) to use for the variability test.  Also changed
	the Makefile and the test so that both the test harness and the
	dependency checks are passed in the SAS build, as well as updated
	the documentation.


	
Version 1.0 -  2004-05-19 (NW)
----------------------------

	- Ekstest, a version of lcplot which contains only the variability
	tests and namely the kolmogorov-smirnov test, where the results
	are written directly into the header information.
	


	
Version 0.1 -  2004-05-14 (NW)
----------------------------
- Directory structure created by pkgmaker.
