Using Scott's code, analyzing the Eztree branches.

Using Alice's code, analyzing Eztree branches.


Using Scott's code, analyzing regular mudst branches.


Using Alice's code, analyzing regular mudst branches.

All the above spectrums use the data from /home/starreco/reco/pp2006MinBias/FullField/dev/2006/089/.

Conclusion: The code used by Alice and Scott is consistent. But the results from Eztree and regular mudst branches are different.

Compare to the data from /home/starreco/reco/pp2006MinBias/FullField/P06ie/2006/089/.

Using Alice's code, analyzing regular mudst branches.

Using simple mudst reader, analyzing regular mudst branches.

Conclusion:The code we get from Alice is right when analyzing regular mudst branches.

Compare to the spectrum from Scott's directory:


Log file from Scott's directory shows that he analyzed the Eztree branches to calibrate the EEMC.

----------------------------------------------------------------------------------------------------------------------------------
Note for the data:
We found two different places store the same data.

Data in directory /home/starreco/reco/pp2006MinBias/FullField/dev/2006/089/ have Eztree branches. while Data in directory
/home/starreco/reco/pp2006MinBias/FullField/P06ie/2006/089/ do not have Eztree branches.

Scott used total 160 files from 2006 day 089 with 1.79M events, while in library-P06ie it contain 156 files with 1.76M events, library-dev has 145 fiels with 1.57M events.

-----------------------------------------------------------------------------------------------------------------------------------
Compare the spectrum a05U123 from different run number using library-dev's data by Alice's code.

Run number 7089008, 7089014, 7089025, 7089091, 7090008 have the identical spectrum. Since run number 7090008 has the same files as Scott use we compare the plot below:


Spectrum from run number 7090008 by analyzing regular mudst branches.

Spectrum from run number 7090008 by analyzing Eztree branches.


Spectrum of run number 7090008 from Scott's directory.

Run number 7089013, 7089015, 7089021, 7089022, 7089024 have different spectrums:

Spectrum from run number 7089013 by analyzing Eztree branches.

Spectrum from run number 7089013 by analyzing regular mudst branches.

Spectrum of run number 7089013 from Scott's directory.
---------------------------------------------------------------------------------------------------------------------------------------------------------------
Run number 7089024 has 6 files which is covenient for us to study one-by-one.
File 7089024-1010001, 1020002, 1030004 have different spectrum, while 1010006, 1020004, 1040003 are identical.

Spectrum get by analyzing Ezt branches from file 7089024-1010001.

Spectrum get by analyzing regular mudst branches from file 7089024-1010001.
