Hi,

But these two plots look like when you look at AGATA from the LYCCA side:

index.php?t=getfile&id=8335&private=0
index.php?t=getfile&id=8336&private=0

...and more important that they don't match in the x axis. Is this because the FRS is using left-handed coordinate system? I wonder the reason to choose left-handed system in the FRS.

Then Michael makes the transformation to rotate the crystals 180 degrees and convert the coordinate system to the FRS coord. sys. (i.e. left-handed).

Then, inside the measurement report, the y and z axis-es are well defined, but there is an uncertainty in the x axis. How are we going to know if the AGATA crystal offsets in the x axis are in right-handed or left-handed system?

Thanks!
Tayfun
