@astro_abbiy@maxisi@physicskaze@farrwill I’m not sure if this is helpful, but I started from this course last year. They are organizing it again this year and it is starting in a few days.

Although both collective measurements are consistent with κ=0 (no evidence for amplitude birefringence), we identified new correlations between attenuation and binary parameters (e.g. spin) when we look into some notable events. (details in the paper)
For the second set, we considered each event to have a specific value of kappa drawn from an underlying Gaussian distribution to investigate possible diagnostics and explore extra physics. (labeled as generic)
And that makes the end of our “post PAX” meeting, hosting 50 gravitational-wave enthusiasts @CenterForAstro @HarvardITC to interactively discuss open problems in #GW astronomy
