# Phase Marginalisation with Parallel Bilby # Phase Marginalisation with Parallel Bilby
## IMRPhenomPv2 TD vs TDP comparison for GW150914 using parallel bilby

* Sampling times using 320 cores (20x16) on ozstar (sstar) \~ 2hr for nact=50 \~ 1hr for nact=20 and \~40min for nact=10 for the TD marginalization.
* [Link to MR](https://git.ligo.org/lscsoft/parallel_bilby/merge_requests/32) implementing improvement which resolves shredding issue without increasing the runtime too substantially

## Example Corner ## Example Corner
The following corner plot is from an injection with SNRs of {H1: 12.89, L1: 10.48}. Note that although the posteriors look a bit messy, this has been made with one run, rather than combining the results from multiple runs.
