L5 (global correlation norm) misfit is negative. How to normalize it?

pplotn opened this issue · 0 comments

Hello, I am using the L5 or (global correlation) norm. As mentioned in the manual its implementation follows (Application of multi-source waveform inversion to marine streamer
data using the global correlation norm, Choi,Alkhalifah, 2012).

Originally it is negative.

I have a question: how to normalize it?

I attached the misfit file. And plots of the misfit functions on attached picture.
