A new program, LSCALE, has been added to the suite. The is a program for the 
scaling and normalisation of raw integrated Laue intensity data to yield 
fully corrected structure amplitudes. The wavelength normalisation curve is 
normally derived internally from the Laue data using symmetry equivalent data
recorded at different wavelengths. As an alternative, where appropriate, the 
normalisation curve may be determined by scaling the Laue data to a reference 
set of data. The program also enables a wavelength and position dependent 
absorption correction to be calculated. Harmonic multiples data may be 
deconvoluted again making use of symmetry equivalent data recorded at 
different wavelengths.

Following the withdrawal of VMS operating system support for the CCP4
program suite, VMS support has now also been withdrawn for the
Daresbury Laboratory Laue suite.

New version 6.0 of LAUEGEN and a new version of INTLDM. The handling of
overloaded pixels within a spot has been changed. In the previous version,
all spots with such pixels were flagged as intensity overloads. Using profile 
fitting, spots with only a few overloaded pixels can still be integrated
to give good intensities. These intensities are determined by omitting 
the pixel positions of the oveloaded pixels from profile fitting mask when 
a spot is integrated. The number of overloaded pixels allowed within a spot, 
to be treated in this way, is set by the user (the new OVLIM extended LDM 
parameter). The intensity derived from any spot with more than the requested 
limit of overloaded pixels is flagged as being an intensity overload. In
addition, when an MTZ file is output, the number of overload pixels within
the spot is stored for each spot. The new versions also incorporates
a new option for handling a cylindrical camera (new LDM keyword DGEOM
(detector geometry) = flat (default) or cyl). Image data types 'mar' and
'pfbyte' are handled. In LAUEGEN, the image display now has separate limits 
for the maximum allowed width (850 pixels) and height (650) pixels.
<P>
<B>NOTE:</B> These versions of the programs require updated versions of
some of the Laue libraries (see update notices for details)

New option in LAUEGEN for simulation of gnomonic projections; implemented
in LAUEGEN version 5.0
<P>
<LI> <I>February 1997</I>
<P>
New option for deconvoluting spatial overlaps added to Q. Hao's integration
routines and implemented in latest versions of INTLDM (Version 1.1) and
LAUEGEN (Version 4.2). <B>Note</B> that spatial deconvolution will always 
be done by the integration routine but may effectively be 'switched off' 
if not requiredd by setting a sufficiently large value for the LDM parameter 
SPOT_EPSILON.

<B>WARNING:</B> Bug found in spatial overlaps calculation when using radial
masking option. Note that the number of spots flagged as spatial overlaps
will increase. The bug fix affects LAUEGEN and INTLDM and the .ge1 files
produced by LAUEGEN.

The Laue Software Suite Documentation has been significantly modified.
It is essentially all available via the WWW through the Laue suite home
page. Figures for WWW access are in .gif format. The distribution version
of the Laue suite contains equivalent documents in a plain (ascii) text
format with Postscript equivalents for the figures. The Web pages and plain
text documents are all generated at Daresbury from the same source (pre-html
or program code) files using the 'extract_doc' program. HTML and/or these
pre-html files could be also made available for distribution if there is
sufficient demand.

A new version of LAUEGEN has been installed. The main additions are new
options to determine spot sizes and to perform spot intensity integrations.
The program uses integration routines written by Hao Quan which are fully 
compatible with all the current LDM developments. 
A more automated crystal orientation refinement procedure has been
incorporated. The main processing options may also now be carried out
via command line requests which may be used with the program in 
interactive, terminal or batch modes. A minor change to the existing 
functions is that output files (e.g. .ldm files) that already exist 
may optionally be overwritten.
<P>
The new version of LAUEGEN make use of a slightly extended set of LDM 
parameters making use of a new facility within LDM to define additional 
LDM like parameters for use in a particular program or set of programs. 
The basic set of LDM parameters remains unchanged and the extra parameters 
should always be regarded as a program specific extension though they 
appear to be handled  as if they belonged to the LDM parameter set. 
<P>  
If you wish to install the new version of LAUEGEN ensure that you also
obtain and compile new versions of the Laue and XDL_VIEW libraries.   
<P>
<B>NOTE:</B> August 1996: The version of the XDL_VIEW library required 
will not be present in the CCP4 distribution until the next release,
probably towards the end of 1996. You can get the required
version from the CCP4 ftp area as xdl_view.tar.Z in pub/jwc

A new LDM compatible integration program INTLDM has been added to
the suite. This makes use of integration routines written by Hao Quan.
The same integration options are also being incorporated into the
LAUEGEN program.

The CCP4 ftp area which also holds the distribution version of the Laue
Software Suite has now been moved to <B>ccp4a.dl.ac.uk</B>.
