====== Broken Bonds ======
===== Noise data available offline =====
The following data was processed using STNZSMonitor by Mark Tobin:
   * 2008 and 2009 data, files abailable in : <code>lhcb@ckm:~/noise/VFS400_NOTP/rootFiles</code>
   * 2010 data (until june) was taken with the TEST recipe, files in: <code>lhcb@ckm:~/noise/TEST/rootFiles</code>


How to reate a compilation of noise data:
    - create a new directory e.g:<code>lhcb@ckm:~/noise/symLinks</code>
    - create symbolic links to all the .root files you want to include in the plots. (The script createSymLinks.sh might be useful).

===== Noise plots =====
== Plots were generated for the following sectors affected by broken bonds: ==
| TELL1 | Sector | first observed | Taken out | noise distributions and noise vs.time |
|  |    |  | | plots for broken channels (range) |
|2 | 3  | June 08  | June 08 | - | 
|3 | 3  | Nov 08 | still installed | 1860-2048 |
|5 | 1  | June 08 | Nov 08  | 512-730 |

   * Noise  pattern (sector): For all sectors listed above the noise pattern (noise as a function of the channel number) of the given sector is plotted for each run listed in the directory symLinks. HV is on (250 V) and there are >=4k Evts used to compute the noise. Plots available: <code><code> lhcb@ckm:~/noise/symlinks/plots/NoisePlots_tTELL1NUMBER_sSECTRORNUMBER/</code>

   * Plots for broken channels (and/or candidates): for all channels having bonds on the innermost bond row two plots (noise distribution, noise as a function of the time) were generated in the range indicated in the table above.  Plots available: <code> lhcb@ckm:~/noise/symLinks/plots/NoiseHisto_tTELL1NUMBER/ </code>

===== Count low noise channels =====
   * Plots (number of bad channels as function of time, for each TELL1, for all TT) available: <code>lhcb@ckm:~/noise/plots/nBadChannels/></code>
