I have, with much help from Bill, been looking at the ADC
info from ecal, including the new outputs with x20
attenuation of the signal. The output is contained in a
glut of histograms in  postscript files ecal795.ps and
ecal801.ps (more will be forthcoming sooner or later) in
fnmint directory [minimax.bj]. For each of the 28 towers
(labeled with Longo convention) there are 3 plots:

     100 series: events vs ecal adc (ped subtracted; unattenuated)
     200 series: events vs ecal adc attenuated (ped subtracted)
       0 series: ecal atten adc value vs ecal unattenuated value.

There are 4 plots per page. The 100 and 200 series are semilog
(important!), and the 0 series linear scale.

For the record here is the map information I use. In addition to
the adc indices and Mike's labeling, I also include my labeling of
the blocks ("block") which I used to produce hand-scan displays.
Looking from C0 I start from the top left (big v, small u) and
end at bottom right (neg v, large u):
