• 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.
