Hi Mike thanks for this supporting information. I will start the interpolation. Is there any prefered method for this? Can I use a bilinear approach. I think this is as far as I can take it though - as I have no understanding of lwave.cpp and the file construct. Will it be ok to post a txt file on the list with the interpretation results?
