# Remarks:
# 1. Absorber and station positions are defined relative to MuchCave Zin
#
# 2. When defining distances between absorbers and stations keep in mind 
#    the following technological restrictions:
#    a) distance from layer center to absorber >=   5 cm 
#    b) distance between layer centers         >=  10 cm 
#
# 3. Absorber materials currently implemented:
#    I - MUCHiron
#    L - MUCHlead
#    W - MUCHwolfram
#    C - MUCHcarbon
#    P - MUCHpolyethylene - 30% borated polyethylene
#
# 4. There is a possibility to switch off detailed module design 
#    (Use module design = 0). One large module per layer is created 
#    in this case (at the front side of each layer).
# 
# 5. If detector type = 2 (straws), support will not be created.
