averaging data shown on the graph

[halludasa]

I need to find the average of the data shown by white line in the graph attach. I know there are 160 peaks in the data. The graph below shows how the peak looks like when you zoomed in.

Are these peaks always going to be happening at the same location each run? You can just index the array and do the averaging that way. 

If you have to programatically locate these peak values it will be a bit trickier...

I would just do a simple moving average.  Look into the Mean Pt By Pt VI.
