---------------------------------------------------------------------
Version 2.8.2 - 2016-11-03 (AI)
------------
+ DATAMAX quality check removed if exposure map is in lambda
space.
+ Documentation updated.
Version 2.8.1 - 2014-09-10 (AI)
------------
+ Bug using rebin parameter in lambda space fixed. SOC-SPR-6923 closed
Version 2.8 - 2012-12-17 (AI)
------------
+ reproject method used to calculate AREASCAL and BACKSCAL in lambda space has been removed.
+ Given the new functionality in rgsfilter and rgsregion that generates the exposure maps
and regions in lamdda space, rgsspectrum can calculate the AREASCAL and BACKSCALE
without any reprojection. These modification close SOC-SPR-6688.
+ documentation updated.
Version 2.7.5 - 2011-02-16 (AI)
------------
+ Background corrected RGS spectra cannot be read int XSPEC 12.
BACKSCAL keyword added for background subtracted spectrum (S0C-SPR-6647)
Version 2.7.4 - 2010-04-01 (AI)
-----------
+ Default value of parameter "spectrumbinning" changed to "lambda".
Version 2.7.3 - 2010-04-01 (AI)
-----------
+ Back to version 2.7.1. The modification introduced in version 2.7.2.
has to be implemented together with a modification in rgsrfmgen.
The SOC-SPR-6577 means: Accumulate counts in lambda grid instead of
mlambda, which implies changes in both packages.
Nevertheless, we have wrote explicitely in the spectrum header that
the units in the channel axis are: -Angstrom*order
Version 2.7.2 - 2010-03-26 (AI)
-----------
+ SOC-SPR-6577 fixed.
Version 2.7.1 - 2009-09-01 (AI)
-----------
+ Misc. fixes to make gcc-4.3 happy.
Version 2.7 - 2009-03-31 (AI)
-----------
+ The algorithm to calculate BACKSCAL and AREASCAL in lambdabinning has been
modified. Now BACKSCAL and AREASCAL reflect the bin width difference between
beta and lambda binning.
Version 2.6.3 - 2008-06-17 (AI)
-----------
+ Documentation fixed and updated.
Version 2.6.2 - 2008-06-04 (AI)
-----------
+ Mlambda channel index, needed to accumulate counts, is now checked. Only
positive values are allowed.
Version 2.6.1 - 2008-05-23 (AI)
-----------
+ New parameter "spectrumbinning". This parameter allows to calculate
the spectrum in lambda binning or beta binning.
+ "loadEvent" method has been modified to take into account the event filtering in
lambda space.
+ "out" method has been modified to set up the keywords depedending if the output spectrum
will be in lambda or beta space.
+ New method (reproject). Calculates the areascale, backscale, quality
and errors in the corresponding lambda grid.
+ New method (setMLambdaChannel).
+ New error message "LambdaSpectrum" thrown when M_LAMBDA column does not exist
in the event file and the lambda spectrum has been chosen.
Version 2.6 - 2003-04-22 (CG)
-----------
+ C++ compliance increased (required by gcc3.2)
+ DEPEND changed (dal instead of dali)
Version 2.5 - 2002-08-21 (UL)
-----------
+ now DEPENDs on package sas
