GW Open Data Workshop #2: Hands-on exercises

Material to support the GW Open Data Workshop #2, April 8-10, 2019

Software setup

Suggestions for accessing the required software are available in the setup directory

Hands-on Session Program

Day 1

Suggested tutorials:

intro - Introductory tutorials 1 and 2 provide an introduction to data access and resources on the Open Science Center web site.

gwpy - gwpy tutorials 1, 2, and 3 introduce the gwpy software pacakge. This includes a variety of tools for discovering, reading, writing, and plotting gravitational wave data.


  • Discover, download, and read data
  • FFTs, PSDs, and whitening
  • Working with segments lists and Timelines
  • Plot spectrograms to identify glitches, signals, and hardware injections

Day 2

Suggested tutorials:

pycbc - pycbc tutorials 1, 2, 3, and 4 provide an introduction to the pycbc software package. This analysis package is designed to analyze gravitational-wave data, identify CBC signals and estimate their parameters.

skymaps - Skymap tutorials 1, 2, and 3 introduce how to read in and use sky localization probability maps to help identify the likely source locations of observed signals.

parameter_estimation - Parameter estimation tutorials introduce how Bayesian inference is used to fit model waveforms to the data.

intro - Introductory tutorial 3 provides an introduction to using matched filtering to identify CBC signals


  • GW signals from compact object mergers
  • Matched filtering to identify compact object mergers
  • Working with compact object merger parameters and waveforms
  • Working with skymaps to identify likely source locations

Day 3:

Suggested Tutorials:

  • Complete tutorials from days 1 and 2


  • Parameter estimation
  • Explore CBC workflows
  • Collaborate on individual research projects
  • Begin work on "more to explore" advanced excercises
