Subject: Xray energies - 1. calibration 
Year:  
30angle:  E[keV] = 0.0158507 *ch-2.07456
90angle:  E[keV] = 0.01950*ch-2.76
145angle: E[keV] = 0.017988  *ch-1.809

I could identify 2 peaks in the 241Am spectra and 4 peaks in the 133Ba. These peaks are fitted with a gaussian to get their position --> linear energy calibration for the combined (Am+Ba) data sets for each detector. The function I used: E(ch) [keV] = m*ch+b
