Recent Ring Heater Tests Compared using mag_phase_plotter
The past two weeks Camilla has run multiple tests on the ring heaters (73093, 73272, 73289 , 73308), so I updated mag_phase_plotter.py and used it to compare these tests.
It is now easier to add/compare different tests+times with mag_phase_plotter_v1.1.py and the txt file it references, mag_phase_plotter_inputs.txt. Both are currently found in /ligo/gitcommon/labutils/mag_phase_plotter.
Note: We had to replace the LSC-POPAIR channels so we replaced them with LSC-POP_A_RF{9,45} channels for now, and it looks like RF45 is not useful for us when looking at the ring heaters. This will be changed out as soon as we find a better channel.
