<H1>PSD-TRICS Count and Tricsscan Command</H1>
<h2>New Commands</h2>
<p>
As of 2005, the normal SICS scan command can be used for TRICS. There is
now a special command:
<pre>
scan2d
</pre>
which switches to PSD scan mode. Switching to single detector mode is
achieved through:
<pre>
scan1d
</pre>
H, k and l are now virtual motors in SICS and can be scanned normally.

<h2>Obsolete Commands</h2>

reflections will be searched in normal beam geometry. psdrefscan, however,

for a PSD HKL scan, all commans have to start with hklscan2d.
