  • The code explicitely assumes that there is one events extension per file. Future decisions to pack lots of extensions into a single FITS file are not yet supported!

  • For the obscat to work, the relevant parameters must be stored as keywords in the primary extensions of the events files.

  • The method of storing HK parameters for ASCA has changed, so that now all the HK data for the whole sequence is stored in one file. Xselect does not support this format automatically, so to view the HK data, you must read it in by hand using the read hk command.
