+    High Heat Load Slit.
+
+    There are no independent parts to move, so each axis only has center and size.
+
+    Based on the 25-ID-A whitebeam slits.
+
+    The motor parameters listed below specify which motor records
+    control which axis. The last piece of the PV prefix will be
+    removed, and the motor number added on. For example, if the prefix
+    is "255ida:slits:US:", and the pitch motor is "255ida:slits:m3",
+    then *pitch_motor* should be "m3".

+    Parameters

+      EPICS prefix required to communicate with HHL Slit IOC, ex: "25ida:slits:US:"
+    pitch_motor:

+    yaw_motor:
