a) Jaakko: update programs in the CERN repository.

b) Yuri: possibility to put a small single turn NMR coil inside the target 
material made of 1 - 2 mm tube and covered with teflon insulation. The coil 
should be away from the target holder walls. It produces the main radio
frequency field along the static 2.5 T field. The radial field is however
enough for NMR detection and there is no danger of superradiance. This coil
could be also used for the nitrogen-14 or transverse polarization measurement.

c) Michael gave a talk on the analysis of the 2010 polarization data. 
The bachelor thesis is now on the COMPASS web

d) Kaori: the correction factors for the negative solenoid current sign
change a little during the run. Thus a small residual modulation is seen in
the calculated polarization values. With more careful analysis this 
modulation could be significantly reduced. See the notes
