ceffyl 1.25

Software to rapidly and flexibly analyse Pulsar Timing Array data via the Generalised Factorised Likelihood (GFL)method

ceffyl

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, some non-python dependencies are required. You can find these in requirements.txt

First, clone the repo

git clone [e-mail]:astrolamb/ceffyl.git

Then pip install :)

pip install ceffyl

examples
