Hi Matthew,
thanks for the comments. I will try to answer.
1) To calculate the resolution I needed only four, that's why I didn't 
show all of them.

2) I saw that double peak structure...but unfortunately I have no 
explanation for that. Probably some calibration constant changed!??! One 
could check direct the I/Q values but I didn't do so far.

3) I just wrote down in a approximate way the numbers.They should be 
corrected before any publication.

4) In principle you are right: in general what we need is a relation 
like Y = X + constant. Since we normalize everything at the end, any 
constant does not play any role so I omitted...

5) In the text I meant the relative difference between magnets. If they 
all would have the same offset, It wouldn't be a problem.

6) ArcTan(0.4374) = 0.412326504 radians = 23.62 degrees... Sorry I wrote 
a bit wrong:-) Did you mean this?

hope to hear other comments :-)))
