Power spectra pipeline for Cosmic Dawn, Epoch of Reionization radio interferometric experiments

Project description

Power Spectra Generation pipeline for CD/EoR experiments

pspipe is an analysis pipeline which aims to make generation of high precision power-spectra for Cosmic Dawn and Epoch of Reionization experiments as easy and reproducible as possible. pspipe is the default analysis pipeline of the Lofar-EoR and NenuFAR CD projects. It performs all tasks from calibrated data to final the power-spectra, including:

  • Post-calibration flagging (using AOflagger and SSINS)
  • Visibility gridding (using WSClean)
  • Foregrounds modeling and removal (using GPR, GMCA, polynomial fitting)
  • Optimal power-spectra generation (using ps_eor)

Thanks to its multi-nodes concurrent processing, pspipe is also very fast at crunching hundreds of hour of calibrated data.


pspipe can be installed via pip:

$ pip install pspipe

and requires Python 3.7.0 or higher. For certain tasks, you will also need DPPP and WSClean
