1. Introduction
a) 3D PSF without pile-up b) 3D Pile-up PSF
• Goal of the project: verify that the results of spectral parameters analysis do not depend on the extraction region.
• If there is pile-up: extraction of the core. But... which is the impact?? what are the consequences??

Method:
• Selection of a circular region and extract spectrum from all different annuli
• Spectral fitting for all the individual spectrum
• Compare results for different annuli within
•(a) full band
•(b) narrow bands
• Connection to XCAL archive:
•source and background region
•model for fitting the spectra.

Conclusions
• We see changes of spectral parameters dependent on the source region definition.
• Interpretation:
• Reasons:
