Dear Marc,

sorry I missed you previous email.

I try to answer some of the questions you ask, for the front INFN GEM layers:

>  1.  Are these dimensions for the cable tray accurate?

     the dimensions of the metallic cable tray look correct (they are expected
     to be identical in all layers).
     In the front layer, the single cable try is 63.8'' (~162 cm) long


>   2.  What is the distance between the baseline of this cable tray and the

     for the front layers: 
       - the cable trays are separated by 5.53'' (~14 cm); this is the distance
         between layers; 
       - the "left" and "right" cable trays on the same layer are separated by
         ~27'' (~68 cm)


>   3.  Are these numbers the same for the front layers, if not what are the

Best,
Evaristo
