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 2 minutes to fully compute the coverage profile.

Disclaimer: The DECam Footprint currently breaks in the calculator. We are temporarily approximating its coverage as a circle with 1 deg radius.

Instrument Depth Depth Unit Approximate For footprints with multiple ccd's this will approximate the calculator's input by using a simplified instrument footprint without chip-gaps. It is substantially faster, but does introduce a level of uncertainty in the resulting area and probability.
