Vicky,
So I'm not 100% sure what is going on here. The code looks as if it is
trying to pick at exactly the same PPM value, but it is possible that the
fitting routine is moving the peak afterwards. Anyhow, I have made a small
change which should mean that the PPM value of the copied peak is solid.
Let me know if this is OK.
