Hi George,
:) Yeah for the tutorial, I used TAN+RAD references together, but only for TAN OPMEG sensors
On another point, I have noticed that the synthetic gradiometry sometimes spreads noise across the frequency spectrum, rather than reducing it. Perhaps we could look at this together next week?
Would also be very interesting to test (when back in the lab) whether adding more references around the room is able to help regress out even more noise...

Excellent, thats good. I am now placated.

Yes this is an effect I have seen a few times too. We should open a new issue about that?
It shouln't do this unless we are doing some kind of additve process (maybe trying to double regress the same signal???). I feel like Tim may have already have some intuition as to across why this happens but this should be something we can get a handle on when I look a bit more at the code.
EDIT: I think I have misunderstood the code - nevermind. But I'll keep the question below just incase I was right the first time? I need more tea. - Sorry!
