PyFstat

This is a python package containing basic wrappers of the lalpulsar module with capabilities to perform a variety of searches, primarily focussing on semi-coherent glitch searches.

Examples

All examples can be run from their source scripts in examples, or for each example there is descriptive documentation:

• Making fake data with and without glitches
• Fully coherent MCMC search
• Fully coherent MCMC search on data containing glitching signals

Installation

The script can be installed system wide via

python setup.py install

or simply add this directroy to your python path

Ephemeris installation

The scripts require a path to ephemeris files in order to use the lalpulsar.ComputeFstat module. This can either be specified when initialsing each search, or more simply by playing a file ~/pyfstat.conf in your home directory which looks like

earth_ephem = '/home/<USER>/lalsuite-install/share/lalpulsar/earth00-19-DE421.dat.gz'
sun_ephem = '/home/<USER>/lalsuite-install/share/lalpulsar/sun00-19-DE421.dat.gz'

where this uses the default ephemeris files provided with lalsuite.

Dependencies

• swig-enabled lalpulsar, a minimal configuration is given by

./configure --prefix=${HOME}/lalsuite-install --disable-all-lal --enable-lalpulsar --enable-lalapps --enable-swig

• emcee¹
• corner¹
• dill¹
