Timelines are available to display times when a number of GW instruments were collecting data, as well as data quality and injection information. This information can be retrieved as a plot, an ASCII list of segments, or as JSON data. A simple URL pattern is all you need to find the segment information you want. To see how these URLs are constructed, fill in the information below, and see the URL that appears at the bottom of the screen.
