PhenomPCore_mcmc

This script either generates (default) or plots (by adding the option: –filename_plot) an MCMC chain describing the posterior probability of a model (generated from LALSuite; see below) fit to a two-file dataset (given by the optional positional arguments; a default dataset stored with the package is used by default, if no positional arguments are given).

The model is generated with the call:

lalsimulation.SimIMRPhenomPFrequencySequence(…)

which calls the C-function XLALSimIMRPhenomPFrequencySequence. That function then calls PhenomPCore which in-turn calls PhenomPCoreOneFrequency.

PhenomPCore_mcmc [OPTIONS] [DATA_FILES]...

Options

--filename_plot <filename_plot>

Specify a chain file to plot.

--filename_out <filename_out>

Specify a file name for chain output.

--n_walkers <n_walkers>

Specify the number of emcee walkers to use. [default: 100]

--n_steps <n_steps>

Specify the number of emcee steps to take [default: 2000]

--freqs_range <freqs_range>

Specify the frequency range of the fit as MIN MAX.

--use_buffer, --no-use_buffer

Use a buffer for acceleration. [default: True]

--n_streams <n_streams>

Number of asynchronous streams [default: 0]

--legacy, --no-legacy

Specify this option if a legacy version of LALSuite (without buffer support) is being used. [default: False]

Arguments

DATA_FILES

Optional argument(s)

PhenomPCore

This script calls a higher-level function in LALSuite. The output is two binary arrays corresponding to the two outputs hp_val, hc_val from PhenomPCore.

The outputs are arrays of complex numbers; one for each frequency bin.

The call:

lalsimulation.SimIMRPhenomPFrequencySequence(…)

calls the C-function XLALSimIMRPhenomPFrequencySequence. That function then calls PhenomPCore which in-turn calls PhenomPCoreOneFrequency.
