DX Closed Dome Performance

ARGOS CalUnit (20170509)

The performance results below are from measurement taken with the ARGOS CalUnit.

We collected AO Telemetry data and LUCI images for bin 1, 300 mode and 400 mode reconstructors.

The loop parameters were similar in both cases, with the loop gains determined via the Optimize Gain routine.

A 1.6" seeing disturbance was applied to the AdSec. Note, this 1.6" seeing disturbance file was calculated for the RetroReflector so with the single pass ARGOS CalUnit we are actually applying only half of the disturbance to the wavefront. This can be seen in the tables below where the Open Loop Seeing (OL) is reported to be slightly around 0.8".
