Code to produce this data (up to RNG seed values) can be found in this corresponding GitHub repository.

memory_posteriors.zip contains the memory posteriors obtained for each event; the file structure is:

event

histogram_*.png (histogram of memory enhancement factor draws from each model's posterior)

memory_results.h5

waveform model

A_hat (mean of memory Gaussian)

A_sigma (width of memory Gaussian)

A_sample (draw from memory Gaussian)

log_likelihood (log likelihood of memory model)

log_weight (importance weight of memory model)

hierarchical_results.zip contains the hierarchical and forecast results; the file structure is:

auto_o1o2o3o4a_{joint,memory}

result_{joint,memory}.nc (posteriors from hierarchical inference)

many other files such as events used, log files, result plots, etc.
