Create an image that shows the density of events in different orders
tg_osort_img evt1a.fits outroot
The order sorting image created by tg_osort_img allows the
user to visualize how the chip energy of an event compares to
the energy determined from the distance to the source and the
assigned order.
Output files have the designated rootname. Two plots in FITS
format are produced for each grating arm: all the events in
the arm and the events assigned to orders 1, 2, and 3.
This script is used in the Create an Order-Sorting Image thread.
tg_osort_img acisf01010_000N001_evt1a.fits 1010
Create order-sorting images for ObsID 1010. The output
files will have a root of "1010". Four files are
produced, two for each of the HEG and MEG grating arms.
The script produces the following screen output:
