Dear Marek,

You will find a .ps file attached which is a first tentative to estimate
the total noise (ele + U). I have followed more or less the Bob's recipe

  There are 4 plots per page corresponding to one defined layer it is order
  in increasing layer number from 1 to 17 ..
  In each set of 4 plots you have
  1- capa fron Dan Owen database average over phi in nF
  2- U noise from John scaled by sqrt(5.5) in Gev
  3- elec. noise calculated with the Dean's formula and assuming that
     U-noise and ele. noise are the same in the layer 3. in Gev
  4- the convolution of u noise and ele noise in Gev

  The data range from eta =1 to 37  I assume the value are the same for
  eta<0 per symmetry
  I put the corresponding files (capa, U noise, ele noise, results) in
  D0mino  ~petroff/calib/noise

  Remark:
  1-the layer 1 1,2,3 shows a rise of U noise for eta>34 this not the
  case for the capa so I have not taken into account this rise for the
  elec. noise.
  2-no subtlety concerning mixed geo vs plate geom (see Bob's proposal) in
    the final result.

  I hope this level 0 work will help !
                                          kind regards
                                              PP
