BS is a windows version of the 2D X-ray data processing
program BSL in use at the Daresbury Synchrotron radiation source, for the
treatment of low angle diffraction data. BSL was written in the Daresbury
Laboratory, mainly by Geoff Mant, for the Biology Support Laboratory. It
is based on the OTOKO package developed in Hamburg in 70's and runs on
Unix or Unix-like platforms. You may find more information about it on
Daresbury web site:
www.srs.dl.ac.uk/ncd/computing/manual.bsl.html.
The core of BS was written in April - June 2000
to make it possible to work with Daresbury data on our home, Windows-based
computers. Another aim was to make it more user-friendly and to provide
greater flexibility to adapt to the ever changing requirements. It requires
less memory, has separate window to see 1D graphics and allows export of
the image in two common formats: BMP and TIFF. It is still developing,
comments and suggestions are welcomed.
The program was written using CBuilder 4, the
codes are available on request.
