EPC failed to get the inverters to boot up.  It is possible the batteries are not compatible with the new inverter.   More research is needed.

Kcor realtime software

This afternoon the kcor pointing control software was changed to be less aggressive in its tracking.  We only look at the pixels near the occulter instead of the full array.  And we have decreased the exponent in the exponential moving average and seen a smaller fraction of the correct at each period.   The tracking seemed to do ok during the heavy aerosols.
