... Watchouts . ... Help . No, but maybe you have the wrong version of ds9 installed. A bug was in fact recently discovered in version 2.2.1 of ds9 , when used in conjunction with SAS v5.4. When importing a spatial region (either in sky - X/Y - or detector - DET[XY] - coordinates) into xmmselect , the coordinates in the corresponding selection expression are totally out of bounds ( i.e. larger than, say, 1E+05). ... Any question about SAS should be addressed to the XMM-Newton help desk . ...

This is not as trivial a question as one might think, since it is not enough to know the location with respect to the Earth and/or the Sun in some arbitrary coordinate system. One may have to consider things like differences between the solar equatorial plane and the Earth's orbital plane, the changing direction of Earth's spin axis during the year, and the magnetic dipole orientation. ...

. A regular expression is a concise way of expressing any pattern of characters. You construct a regular expression by combining ordinary characters with one or more metacharacters: characters that have special meaning for the shell . Regular expressions can be used to: . specify filenames . search file contents . change file contents . Commands differ in the range of the regular expressions that they support. Check the manual page for the command for further details.
