Find the best parameters¶

	aia_area	aia_contour	chisq	nustar_fac	xrt_area	xrt_fac	xrt_submap_radius	aia_ratio	xray_ratio
0	1.916528e+16	75.0	0.971649	1.0	8.110882e+17	2.5	7.0	0.856826	0.988443

These results (measured by aia_ratio and xray_ratio, the total of the ratios between DN_in and DN_reg for the given channels in those ranges) are not too much different from those using the default inputs where xrt_fac = 1.

For those inputs, aia_raito=0.831655 and xray_ratio=1.007023

DEM at selected times - similar area AIA & XRT¶

why this is not a good choice (at least, using DEMreg) since it does not result in good fits
