Description

  • The map above is movable. The image is shown in significance with a squared root color map ranging from 0 to 25. The black and blue colors correspond to pixel values from 0 to 2. The red pixels have values of around 5. The yellow to white color transition corresponds to 15 and more.
  • The regions of high systematic noise are shown with yellow circles.
  • Clean button loads sky mosaics made without pointings on bright sources to suppress systematics. Original shows mosaics with all data available.

    Flux and error maps are in mCrab units. All maps are convolved with instrumental point spread function (PSF) which is Gaussian (σ=5'). Exposure maps are in ksec.
