When trying to implement new feature we have figured out in literature, that declination against grid north is called "needle deflection". Is this english term, OK? It means, instead of declination, you would specify needle-deflection 10 deg In Slovakia, we call it "magnetic deflection". Or may be just declination-north grid would be sufficient. Any comments? S.

** Yes please - that would help a problem I have with the Upper Flood data where much of the "old" data is declined against Grid North, and hence all my "new" data has also been delcined to Grid North too. When I add the CS option, the data is rotated by 0.55 degrees (the Grid to True difference in UK).

Do you mean adding some option, that would specify, that given declination is not against true but grid north?
