Hrc I Background Maps

The background map is created as follows:

The table blow shows an overview of stowed background changes over years. The fist column is year, the second column is a dead time corrected yearly comulative background time. The third column is a stowed background map with event 1 data scaled so that details show up. The fourth column is the same data but unified scale for all years. The fifth and sixth columns are similar to those of the third and the fourth, but status bit corrected data. If you click on the year or one of the maps, it will take to the larger map of the map.
