Fermi Map: Band 1

Listed in IVOA Registry (Virtual Observatory)

This survey sums all data observed by the Fermi mission up to week 396.

Description

This version of the Fermi survey are intensity maps where the summed counts data are divided by the exposure for each pixel (in cm^2 s) and the area of the pixel. Data is broken into 5 energy bands <ul> <li> 30-100 MeV Band 1 </li> <li> 100-300 MeV Band 2 </li> <li> 300-1000 MeV Band 3 </li> <li> 1-3 GeV Band 4 </li> <li> 3-300 GeV Band 5 </li> </ul> The SkyView data are based upon a Cartesian projection of the counts divided by the exposure maps.

In the Cartesian projection pixels near the pole have a much smaller area than pixels on the equator, so these pixels have smaller integrated flux. When creating large scale images in other projections users may wish to make sure to compensate for this effect the flux conserving clip-resampling option.
