RPC Korea working group meeting
    • check the history of noise rate and compare with Silvia's online noise rate
    • merge multiple runs with the same condition to increase statistics in dead channel fraction
    • look at time dependence of noise rate and deadchannel fraction

Info from Silvia

Dear all,

some infos:

1. some online noise results are accessible here:
http://cmsrpc402b20/noise/index.html


2. the root files can be found on the noise server, the instructions to login are here:
https://twiki.cern.ch/twiki/bin/view/CMS/NoiseToolInstructions

What you need to do is:
ssh -X cmsusr0 -l pugliese
ssh srv-c2c03-10
cd /rpctdata/CMSSW/CMSSW_3_6_1/
cmsenv
cd /rpctdata/CAF/
cd run139370 (for instance, if you want to have a look at this run).

For example the file: barrel.root contains the barrel plots, total.root contains barrel+endcap.
If you open one of the Noise_xxx.root files, you can find plots per tower.

The LB plots "a la Karol" are called "summary with sum, WIN", in the Noise files.



3. for the LB files: the area info is in the area_noise.txt file (to be found in the same
directory /rpctdata/CAF/)
The LB name-roll name mapping can be found in the lb-chamber.txt files


4. if you want to join more runs together, it seems the same masking is applied between
runs 139364 and 139916. Anna, can you confirm this?


Please let me know if you need more info.
Best regards,
Silvia
