Coverage Calculator

Calculate the coverage of the GW localization over time, with choices to limit the coverage calculation to particular sets of instruments, wavelengths, or depth. All fields are optional, but cuts on depths must have an associated unit. If an empty form is submitted, the total reported coverage regardless of depth or band is computed. Once a HEALPIX pixel has been first covered, it is marked as done, to avoid double counting probability when the same field is covered multiple times. After clicking, be patient, it may take up to 20 seconds to fully compute the coverage profile.
