MIP response for M-C vs. real data
side-by-side comparisons

1. INPUTS:
   A) 750K real pp200 minB events (used in ETOW calibration)
   B) 500K PYTHIA events with pt=2-3, production 'rcf1231', the softest I found.
   ETOW ADC scale set by 4096 @60 GeV Et w/ SF=5%, pre & post gains are EQUAL @23000 ch/1GeV energy lose.
   B-1) slow simulator, default settings
   B-2) fast simulator
   C) 1 muons per eve, 100 eve, pT=20 GeV, aimed at tower 03TC10, fast simulator

2. Response of one tower 03TC10 & pre & post-shower.
   Black=raw spectra. Red MIP condition on all except this element. Hash blue - 6-fold MIP condition.
   R is the ration between hash-blue & red

   real pp200	.	M-C , slow sim	.	M-C , fast sim	.	1 muon per eve, fast sim
   MIPs yield per tower = 48/750K		MIPs yield per tower= 74/500K		MIPs yield per tower= 144/500K		MIPs yield per tower= 91/100eve

   Remarks:
   * slow simu does not smear pedestals for zero supressed pre/post channels.
   * MIP yields per input events agree within a factor of 2
   * post hower ADC's in M-C are twice higher than in real data

3. Response of SMD on plain 3V
   Energy sum from pair of strips in on X-axis. The X range is frozen to [0,5] MeV. Each plot shows 12 consecutive pair is strips.
   Landau is fitted to each spectrum. The last two plots in the last row show distribution of the Landau mean (X=0-3 MeV) and 'sigma' (X=0-1 MeV)
   Distribution of MPV vs. strip ID is shown in the second row of the table

   Remarks:
   * Absolute SMD gains changed from 1.3 (blue line) to 1.4(red line) for real cucu200 vs. pp200 events.
   * Absolute scale of SMD gains is wrong. Needed gain correction is of ~1.5
   * Despite slow simu being ON the real spectra are ~2x wider.
   * Slow simu des not change gains but broadens the spectra, stil not enouh

4. Response of SMD averaged over many plains. Blue line was the goal.
