<para>This chapter is untested documentation. It was inherited from the velocity selector
documentation, with alterations based on an email from Ferdi to Andy on 11th May 2011. </para>
<para>The Astrium Disk Chopper is a SICS script context object???. There should be 2 parts,
the script context object, which has the name
<command>/instrument/disk_chopper</command> and the 2 driveable interfaces to the
object, which have the names <command>chopper_speed</command> and
<command>chopper_phase</command>. Hence you can <command>drive</command> and
<command>run</command>
<command>chopper_speed</command> and <command>chopper_phase</command>. To get other
parameters use <command>hget</command> or <command>/instrument/disk_chopper/</command>.
<command>hset</command> doesn't work for these nodes. </para>

<para>The disk chopper is under the
