- The crystal settings calculation in hkl now tried to put omega into the limts by calculating a delta omega. - TRICS data files now include HKL and the UB - The scan module has been expanded to support user defined scans which run a script at any scan point. - A small fix to the PSD code in SinqHM_srv_filler

\subsection{User Scans}
|
|
When operating with polarisation equipment a lot of things must be done
|
|
at each scan point: count, switch sloppy flippers, drive magnetic
|
|
fields, count again etc. In order to do that and other special things user
|
|
configurable scans have been introduced. For such scans a configurable
|
|
script procedure is called at each scan point with the current
|
|
scan point number as an argument. This script then has to perform
|
|
the necessary counting operations, store the data collected, print
|
|
status information and update the internal scan data structures with
|
|
the collected data so that data may be plotted or analyzed in SICS.
|
|
|
|
In the following section the internal scan object is referenced as xxxscan.
|
|
The script can contain the following commands:
|
|
\begin{itemize}
|
|
\item Normal SICS commands for driving magnets, counting, retrieving
|
|
data etc.
|
|
\item {\bf xxxscan line bla bla } appends everything after line to
|
|
the data file.
|
|
\item {\bf xxxscan store 1 2 3 4} stores the numbers after store in the
|
|
count data structure of the scan module.
|
|
\item clientput allows to write information to the controlling terminal.
|
|
\end{itemize}
|
|
|
|
In order to do all this some configurable scan functions have to be
|
|
overloaded. This is implemented in userscan.c. In terms of a public
|
|
interface only one function is defined:
|
|
|
|
@d usinter @{
|
|
void ConfigureUserScan(pScanData self);
|
|
@}
|
|
|
|
which simply sets the necessary function pointers in pScanData.
|
|
|
|
@o userscan.h @{
|
|

|
|
called.
