+ EM Calorimeter Parameters with AstroPix
+ THIS IS A SPECIAL VERSION WITH ONLY THE FIRST IMAGING LAYER ENABLED
+ FOR TRACKING DEBUG PURPOSES ONLY
+ ---------------------------------------
+
+
+ To change the number of imaging layer slots from, e.g., 9 to 6,
+ change EcalBarrelImagingLayers_nMax variable. Note that this does NOT change the
+ number of silicon frames, as each silicon frame and layer is placed manually.
+
+ This file assumes the EcalBarrel_enable_staves_N variables have been defined to allow
+ changing the configuration by enabling/disabling staves
+
+
+
+
+ Active part of the calorimeter is
+ 435 cm long
+ -41.25 cm offset

+ For W/SiFi (sPHENIX): X0 ~ 0.7 cm (but different fiber orientation)
