1. Test for AR Xrays with XIS 1 Black, T = 8 MK, EM = 1.0e47 cm -3 (RHESSI) Red. T=5 MK, EM = 1.0e48 (GOES) Blue, T=10 MK, EM=1.0e44 (RHESSI DEM) Flux at Minimum distance: 0.045 AU Includes 9.6 cm 2 area, and shield transmission. All peaks are around 8keV

2. Test for AR Xrays with XIS 2 Here is plotted the flux in photons/second from 6 to 20 keV, versus distance from the sun. Black, red and blue are the same models. The peak is at 65 photons/sec.

3. Test for AR Xrays with XIS 3 This is the number of days for which the photon count rate is greater than the flux value on the X axis. The blue and red models don't show up much, but you really need to integrate over the whole EM distribution.

4. Test for AR Xrays with XIS 4 This is an average of DEM measurements obtained using RHESSI/GOES during 2002. Error bars are from the spread of measurements during the year; they don't reflect the error in the individual measurements, but the variation in activity.

5. Test for AR Xrays with XIS 5 This is the observed photon flux at the closest approach, black is the, average value, blue is the upper limit, red is the lower limit. Peak is still at about 8 keV, at about 30 photons/(sec- keV), but the spectrum doesn't drop off as quickly at higher energies.

6. Test for AR Xrays with XIS 6 This is the photon flux versus distance from the Sun for each case. There are plenty of photons here.

7. Test for AR Xrays with XIS 7 This is the number of days for which the photon count rate is greater than the flux value on the X axis. Next step is to add a realistic time variation.
