+====== tof Peak Shapes ======
+There are several macros for tof peak shapes for different instruments on the user macros page.
+For powgen the following peak shape seems to work reasonably (though only tested on lowish quality data):
+<code topas>'{{{ instrumental peak shape for this bank here
+   push_peak
+   TOF_Exponential(a0_1_bank5, 25.09796`, a1_1_bank5, 58.58890`, 1, difc_bank5, +)
+   bring_2nd_peak_to_top
+   TOF_Exponential(a0_2_bank5, 40.39882`, a1_2_bank5, 1260.50074`, 4, difc_bank5, +)
+   scale_top_peak @  25.2088988` min 0.0 max 200
+   add_pop_1st_2nd_peak
