Hi Matthew,
It's so exciting to see your response in here because I've been reading
your paper! It's very recent paper and I couldn't be found in Google
Scholar yesterday, but I was lucky to find it in your website. In fact,
seeing your response makes me feel, ah, I've come to the right place!
Anyway, I'll continue my information-digging and see what I can find.
Andrew, thanks for your input. I also tried in OriginLab like you did, but
no good fitting was achieved. I'll see if I can try some other ways...
