At this point the data has been corrected for exposure time and the variations from the effective area of the telescope detector combination the next step is to examine the spectrum. This is done using the plot_data command in ISIS. First we select the flux corrected dataset,
isis> use_flux;
Using flux-corrected data
and next we plot the data.
isis> plot_data(10);
