This is an expanded view of the MEG first-order counts spectrum in the vicinity of some lines. Figure 4 . The same lines of the previous figure are shown, but for HEG first order. The higher resolution is apparent. At the bottom is an expanded view of the photon distribution.
Spectral lines show up as vertical bands.
These are shown in white points in the graphic. One million input photons gave 124,000 ouput photons for an equvalent exposure time of 36 ks. Four million input photons resulted in 85,000 output for a 39 ks equivalent exposure time. The emission measure distribution for the UX Ari model spectrum, which specifies the contribution of each temperature over a range of plasma temperatures. It is interesting to examine the same model for different number of total counts.
