Entry number 320590

This entry is a followup to: 320586

Runs with raster unsyched and Pb/D tgt #3 at 50 uA.
Integ time = 3920 (normal value).

Run 3405 with Octet helicity pattern.  Det_all RMS = 490 ppm
 
Run 3406 with Quartet helicity pattern.  RMS = 575 ppm

Curious difference between octet and quartet.
Seems to be more or less reproducible.

Leave at quartet for now.  About to switch targets ...
