Control of the program is accomplished through a parameter file using the IRAF parameter interface library. It has been successfully compiled under SunOS, Solaris, and Linux. Sample Simulations 5.1. A simulation of a stellar coronal plasma as detected by the HETG with the ACIS-S detector. In the upper panel, an expanded view of the detected photon distribution is shown.
Spectral lines show up as dark, vertical bands.
The lower panel gives the total counts per pixel for the region of the spectrum shown in the upper panel. UX Ari is a bright RS CVn binary system-a prototypical coronal source. Figure 1 shows an expanded view of a portion of the detected HETG image as well as the extracted spectrum. A2029 is, however, an extended object making analysis of its spectrum more involved. A simulated AXAF observation of the A2029 cluster of galaxies.
