Overview

Updated the h1calcs model to include modifications from LLO, restarted the DAQ system (LHO WP #6238). Now H1 and L1 are running the same version of the CAL-CS model.

Details

• CTRL_DELAY filter bank was added to the DELTAL_CTRL signal path, before the summation with DELTAL_RESIDUAL (see LLO alog 28268).
• Reverted some modifications to BUFFER_AND_AVERAGE.c, currently using version of the script in CDS SVN r14393 (see LHO alog 30293).

After the DAQ restart the coherence calculation settings were changed to:

Number of averages: H1:CAL-CS_TDEP_COH_BUFFER_SIZE 13
Seconds between averages: H1:CAL-CS_TDEP_COH_STRIDE 10

The new CTRL_DELAYfilter is currently empty (unused), and the DELAY_CYCLES (ring buffer / integer delay cycles) is set to 7.

The synchronized oscillators in the CAL-CS time-dependent parameter and coherence calculations were restarted manually. This is a necessary step to get correct phases in the oscillators after a model restart (a bug is described in LHO alog 30220).
