Note: cursor timing selection is now done with the command
FILTER TIME CURSOR
(the light curve has a few bad points which i wish to exclude)
session1:ROSAT-PSPC > filter time cursor Type: - click to include a time region c - to cancel cursor selection e - makes the selection excluded l - puts cursor on the left r - puts cursor on the right x - to exit cursor selection p - to return to PLT prompt - click outside the plot to cancel a selection Enter QUIT at PLT prompt to continue(2 clicks define a time for inclusion and these are written to session1_cursor_gti001.xsl save these times to a file so you can use them again in a future session)
