||||
* **Parameters**
|
||||
* //destuctor
|
||||
* **Return**
|
||||
* YieldInfo addInfo

### double getValueFromTGraph()
|
||||
[comment]: # ([getValueFromTGraph()](#double-getvaluefromtgraph))
|
||||
|
||||
Reads the expected yields and significances from the TGraph with `name` saved in the `fitFile`.
|
||||
* **Parameters**
|
||||
* string name
|
||||
* TFile \*fitFile
|
||||
* double TMVAcut
|
||||
* **Return**
|
||||

|
||||
|
||||
### bool yieldComparison()
|
||||
[comment]: # ([yieldComparison()](#bool-yieldcomparison))
|
||||
|
||||
Reads the expected signal+background yield and significance as well as the actuall yield and significance and prints the values in a form of LaTeX table er Run
|
||||
* **Parameters**
|
||||
* int Run
|
||||
* double TMVAcut
|
||||
* **Return**
|
||||
* Always 1
|
||||
|
||||
### YieldInfo yieldInQ2()
|
||||
Performs the B plus mass fit in all the Q2 bins to rare data. Loads the results into the YieldInfo.
|
||||
[comment]: # ([yieldInQ2()](#yieldinfo-yieldinq2))
|
||||
|
||||
* **Parameters**
|
||||
* int Run
|
||||
* double TMVAcut
|
||||
* int nBin
|
||||
* bool doFit
|
||||
* bool doFit (if false, don't fit, just read)
|
||||
* **Return**
|
||||
* YieldInfo filled from B plus mass fit to rare data

||||
|
||||
### bool plotYieldInQ2()
|
||||
[comment]: # ([plotYieldInQ2()](#bool-plotyieldinq2))
|
||||
|
||||
Reads the TGraphs with signal and background yields as well as the actual significance. Also reads the CMS's significance (numbers are saved in the function) and plots it all in one nice even though complicated plot, one per Run and one for both runs.
|
||||
* **Parameters**
|
||||
* bool fixRange
|
||||
* **Return**
|
||||
* Always True
