------------------------------------
Measured Statistics (Run 256) about 10h:
GS + 1st excited:
MUGAST(Ex rec) : 2519 (bckg subtracted)
MUGAST(Ex rec + VAMOS) : 1282
Gamma(871keV) : 125 (if subtract bg only 80 cnts)
Gamma(871keV)+MUGAST(Ex) : 68
Gamma(871keV)+MUGAST(Ex)+ VAMOS IC: 27
Deduced gamma efficiency: 68/(2519/2) = 5.4 % ---> to be investigated
------------------------------------
Fit Results Excitation Energy (gated by VAMOS) - sum of two gaussian fit

Some remarks/ correction :
- The top right plot named all gammas in AGATA is in fact already assuming that the multiplicity of charged particle in MUGAST is 1
- All the gammas spectra plotted correspond only to nbtrack=1 (fold = 1)
