Software to rapidly and flexibly analyse Pulsar Timing Array data via factorised likelihood methods (Lamb et al. 2023)

Project description

ceffyl

PyPI version conda-forge DOI

Pronounced /ˈkɛfɨ̞l/ ('keff-ill'), meaning 'horse' in Cymraeg/Welsh 🏴󠁧󠁢󠁷󠁬󠁳󠁿🐎

A software package to rapidly and flexibly analyse pulsar timing array (PTA) data via refiting to pulsar timing free spectra.

This can be done by fitting to a free spectrum of the entire PTA or to individual pulsars!

Installation

To install via `pip', simply use PyPi:

pip install ceffyl

To install via Anaconda:

conda install -c conda-forge ceffyl

data

Download representations of PTA data to accurately fit spectral models with ceffyl!

examples

  • PTA free spectrum refit example

    • This is the fastest and most accurate refit technique. Fit any GWB spectrum that you'd like in < 5 minutes!
  • GFL Lite refit example

    • Fit GWB models quickly and accurately to different combinations of pulsars!
  • GFL refit example

    • Fit GWB and custom intrinsic red noise models to different pulsars quickly! Experimental - use with caution!
