We did another FC scan.

Using 2 differents scales to see the fundamental mode and the other higher order modes we could have a quite good precision on every order peak.

By fitting every resolvable peak by an Airy function and using the ratio Area of fundamental mode / Area of fundamental mode + higher order mode,

We found that 95.24% of the light was coupled into the fundamental mode of the FC.
