Project: Testing Birefringence with 3-OGC events:

Step1:

• Yifan: adding testing parity waveform into pycbc waveform plugin. Done, see waveform

Step2:

• Yifan,Alex: run pycbc_inference with parity violation waveform on 3-OGC. Mostly done, results in Atlas: /work/yifan.wang/2-jianyan/allevents

Step3:

• Yifan, Alex: Postprocessing
• Posterior plots: https://www.atlas.aei.uni-hannover.de/work/stephanie.brown/birefringence/intrinsic/
• Compare with GR: https://www.atlas.aei.uni-hannover.de/work/stephanie.brown/birefringence/compare/
