Getting Started

Welcome! The LIGO Open Science Center (LOSC) provides access to LIGO data, as well as documentation, tutorials, and online tools for finding and viewing data.

What's LIGO!?

Where's the data?

  • The Data Page allows you to download LIGO data.

  • The main data are a time series sampled at 4096 Hz.

  • Data are calibrated so that gravitational wave signals have units of dimensionless strain (ΔL / L).

How do I work with LIGO data?

  • The Tutorials Page gives examples of how to work with LIGO data. If you are a student, this is a great place to start.

When was LIGO running?
