Broken Bonds

Noise data available offline

The following data was processed using STNZSMonitor by Mark Tobin:

2008 and 2009 data, files abailable in :
```
lhcb@ckm:~/noise/VFS400_NOTP/rootFiles
```
2010 data (until june) was taken with the TEST recipe, files in:
```
lhcb@ckm:~/noise/TEST/rootFiles
```

How to reate a compilation of noise data:

create a new directory e.g:
```
lhcb@ckm:~/noise/symLinks
```
create symbolic links to all the .root files you want to include in the plots. (The script createSymLinks.sh might be useful).

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> lhcb@ckm:~/noise/symlinks/plots/NoisePlots_tTELL1NUMBER_sSECTRORNUMBER/
```

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:
```
 lhcb@ckm:~/noise/symLinks/plots/NoiseHisto_tTELL1NUMBER/ 
```

Plots (number of bad channels as function of time, for each TELL1, for all TT) available:
```
lhcb@ckm:~/noise/plots/nBadChannels/>
```
