rotation with unwanted shift to the right

[Peter Van Kranenburg]

Dear all,

When I rotate text that is right under a note, it is also shifted to the 
right. In the example below, I want the numbers exactly between the note 
on the top stave and on the bottom stave. When there is only a "0", it 
is ok. When there are three digits, there is a small shift. When there 
are more digits (e.g. the "0.630947"), the shift is so big that the 
number is below the next note.

I would be grateful if somebody could tell me how to rotate long strings 
without shifting them to the right.

Thanks in advance!

Peter van Kranenburg
