Dear Daniel, Thank you very much for the updates. 
Dear Mate, Thank you very much for the additional explanations. 
Best regards, ShinIchi

>> Dear ShinIchi,

>> measurement. The experimental statistical uncertainties are much smaller

>> Note also that hopefully the 3D measurements are underway (presented at
