XMM-Newton Science Analysis System . ... The RGS is addressed by the task rgsrmfgen . The size of the o/p RMF is dependent on the spectrum binsize and the number of bins in the energy grid, and can be very large. Heavy consumption of disk space is expected. Memory consumption will also be high as the full RMF is held in memory before being written to disk. ... The task directly uses a section of code from the arfgen task. ...

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...
