We have put a few new settings into the ISC guardian, and one should now be able to use it to go to DC Readout.  As of this writing, we have not yet tried to increase the power with the new ASC settings beyond 5W input (bad violin mode situation, see other elog later).

The SRC1 and SRC2 loops are now opened along with the PRC1, PRC2 and INP1 loops, for the duration of the CARM offset reduction sequence.  Yesterday we were able to get past the SWITCH_TO_QPDS with the SRC loops closed, but today both our daytime operator (Ed) and our evening operator (Cheryl) were struggling.    The SRC loops are re-closed during the main Engage ASC set.

We also temporarily increase the test masses' offloading gain to M0 while the SOFT loops get up and running.  This is to prevent saturation of the L2 actuators when we start off with large SOFT offsets.  Since these can cause slow oscillations, I have them turning off again after 90 seconds at the end of ASC_PART3.  To further prevent saturations, we are resurrecting an old decorator by Stefan that checks the size of the output of the SOFT loops, and if they're getting too big, will turn the loops off so that the offloading can catch up, and then turn the loops on again.  This decorator is included in every state between ASC_PART3 and DC_TRANSITION, which is the state that waits for SOFT loop convergence. 

After some OMC investigation and fixing by Rob and Sheila, we are able to transition to DC readout, and have increased the power to 5W.  The ASC loops are all still stable.  Once Stefan has the violin modes damped a little more, we'll try going to higher power.
