+      EM Calorimeter Parameters with AstroPix
+      THIS IS A SPECIAL VERSION WITH ONLY THE FIRST IMAGING LAYER ENABLED
+      FOR TRACKING DEBUG PURPOSES ONLY
+      ---------------------------------------

+    <comment>
+      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
