Thanks for your replies. Husin, is there any justification for the use of the 104 direction in calcite, other than this is the direction that works? I'm all for doing it if it works, but I'd like a little theoretical backup.
Thanks Daniel. I'll put something together for a look-see. What corrections are being used in Maud? Are there any papers on them?
