Fig 1.   Chart showing Telescope Slewing Performance (right) from S1276 Session
The chart show a large number of orange coloured telescope slews (speed 0.5 to 2°/sec), this is due to the use of Composite Slewing Reporting in DeviceHub (to get around the Anomalous Dome Slew Issue) and the consequential difficulty in determining the actual end time for the telescope slew.  The end time is therefore generally overestimated and the speed is underestimated
