... Your main research interests concern neutral hydrogen. ... That means that there must be enormous quantities of gas lying around, waiting for the chance to collapse under its own weight into lumps and form stars and galaxies. If we could actually observe this gas, as it moves around and assembles itself into lumps, we would be directly observing the process of galaxy formation. ... Optical astronomers seem to think that they can observe galaxy formation by taking optical images. ... In galaxies. ...

... rgsfilter creates the filtered event list as an exact replica of the combined event list, then removes unwanted frames and events, and adds the node-specific exposure maps. ... The common practice of including the effective area in the exposure map is rejected because the effective area is handled more correctly by including it in the response matrix. ... The combined map covers the full channel space, so that channel numbers assigned to the events are coordinates in this map. ...
