After setting the DARM offset to 40mA I took another set of SRC tuning measurements, where I changed the SRCL1 offset and measurement the sensing function at low frequencies with Craig's noise_recorder functions. Data folders and figure folders are listed in the table and the sensing function measurements for each are attached in order of detuning (whereas the table is in time order). The first measurement was done when we were around 2hr 51 mins thermalised and the -265 count measurement when we were 3hrs 52 mins into lock. Camilla and I picked out this offset as giving the flattest sensing function (ie. no detuning). I want to do some smoothing of the data tomorrow to make it clearer, however.

To run the DARM injection use noise_recorder/code/darm_noise_injection_caller.py
To run the PCAL to DARM measurement use noise_recorder/code/pcal_noise_injection_caller.py
To process use noise_recorder/code/darm_sensing_function_processor.py
To plot all sensing functions use noise_recorder/code/darm_sensing_spring_comparison.py, which is the png attached.
Elenna added this -265 offset to lscparams.py and I accepted in sdf. See attached.
