0019 To change the number of imaging layer slots from, e.g., 9 to 6,
0020 change EcalBarrelImagingLayers_nMax variable. Note that this does NOT change the
0021 number of silicon frames, as each silicon frame and layer is placed manually.
0022
0023 This file assumes the EcalBarrel_enable_staves_N variables have been defined to allow
0024 changing the configuration by enabling/disabling staves

0149 The envelope for ACTS purposes needs to include only the first layer. The following
0150 definition includes the front support and is tangential to the outer edge of the
0151 first tray. This allows the envelope to avoid the first SFIL.

0161 The layer material for ACTS purposes is at the top level, since the entire BIC detector
0162 is treated as a single layer. The binning should likely be an integer multiple of the
0163 number of sectors, and of the numer of modules.
