Dear Alex,

I went through all the calo documents and have found very little. there
are some missing references and so. I have marked things with acrowrite
directly in the text and put 2 remarks.
the files are at
http://www.jlab.org/~elke/GX_calorimetry.pdf
http://www.jlab.org/~elke/BC_calorimetry.pdf
http://www.jlab.org/~elke/simulation.pdf

cheers elke
