XMM-Newton Science Analysis System . ... Both vignetted and non-vignetted exposure maps are calculated at the same time, thus saving a lot of time. It is possible with eexpchipmap to write exposure maps in chip coordinates, which is desirable for correct production of background maps. eexpchipmap accesses library routines to perform both its exposure calculations and its coordinate transforms, leading to more maintainable code and easier coodination with other tasks. ...
