Hey all,
I'd like to create a composite PSD out of multiple PSDs I've run, just wondering how you would go about acquiring something like that as I'm not familiar with the data analysis technique. I'd like to make a composite of a whole bunch of individual PSDs or even just run the PSD on the averaged(?) raw data. Not sure of how best to reduce this, gimme your thoughts, thanks!

are you talking about something like a 'peak hold' function? If so you can compile your individual PSD's into a 3D matrix & take the max along the 3rd dimension
