 1. If you just want to add experimental resolution to a set of simulated data:
 ```
-./VKAdd -o output.root -r 0.06 input1.root
+./VKAdd -o output.root -r input1.root
 ```
 
 2. If you want add two sets of simulated data (summing), while also adding experimental resolution:
 ```
-./VKAdd -o output.root -r 0.06 input1.root input2.root
+./VKAdd -o output.root -r input1.root input2.root
 ```
 
 3. If you want add a set of simulated data to itself (pile-up), while also adding experimental resolution:
 ```
-./VKAdd -o output.root -r 0.06 -p input1.root
+./VKAdd -o output.root -r -p input1.root
 ```
 
-In the above examples the experimental resolution was set to sigma=6%. You can, of course, chose any value you want.
+The experimental resolution is sampled according to a Gaussian distribution with, 
+```math
+FWHM = \sqrt(p_0^2 + p_1^2 E)
+```
+where $`p_0 = 30.44`$ keV and $`p_1 = 4.159`$ keV$`^{-1/2}`$
