The background map is created as follows:
The table blow shows an overview of stowed background changes over years. The fist row is year, the second row is a dead time corrected yearly comulative background time. The third row is a stowed background map with event 1 data scaled so that details show up. The fourth row is the same data but unified scale for all years. The fifth and sixth rows are similar to those of the third and the fourth, but status bit corrected data. If you click one of the maps, it will take to the larger map of the map.
The color scale of the left side panel is different from a year to a year so that the structure of stowed background can be seen clearly. The color scale of the right side panel is same from one year to the next so that the changes in the count rates can be seen clearly.
