Overlay figures for easy comparison


This tool is designed to help visually correlate multiple types of data by laying transparent figures atop one another. To use it, follow these steps:

  • From the main page(s), drag-and-drop figures onto the button with this icon:
  • Expand this dialog box and use the Overlay button (to the right) to render a new figure by overlaying the ones selected
  • Add more figures using the steps above, click Overlay to re-render, and use the Download button to save to a local file
  • Use the Clear button to clear all figure selections

Note: figures are remembered across tabs, so multiple times and subsystems can be compared at once.

The plots shown below characterize the sensitivity and status of each of the LIGO and Virgo interferometers during the second half of the third observing run, known as O3b, which began on November 1, 2019 and ended on March 27, 2020.
