"Fead an Iolair - Lagdhu" hardanger tuning

Does anyone happen to know what tuning is used on this particular recording? Is it the *standard violin "GDAE" or is it something else?

Also, if anyone happens to have a decent transcription of this tune I would greatly appreciate it though I think I've been able to more or less get the gist by ear.

*as in the actual GDAE on 440, not the Hardanger equivalent which would be BEBF# on 440(?)
