neda_psdcaen_positions.txt had weird values for three first detectors, especially neda_02.

It was:
NEDA_00_position_psdcaen    0
NEDA_01_position_psdcaen    0.22
NEDA_02_position_psdcaen    40

I (AF) make it:
NEDA_00_position_psdcaen    0.2
NEDA_01_position_psdcaen    0.2
NEDA_02_position_psdcaen    0.2
