..Run algorithm on events

---

ranges of various fit parameters, and tolerance to determine that fit is at the limit

Put root into batch mode so that we don't try to open a graphics window

---

Write out the job parameters

---

Clean up existing histograms if necessary

---

Histograms containing the data collected by eclGammaGammaECollectorModule

---

Record the number of entries per crystal in the normalized energy histogram and calculate the average expected energy per crystal and calibration constants from Collector

---

Write out the basic histograms in all cases

---

If we have not been asked to do fits, we can quit now

---

Check that every crystal has enough entries, if so requested

Insufficient data. Quit if we are required to have a successful fit for every crystal

---

Some prep for the many fits about to follow

histograms to store results for database

Diagnostic histograms

1D summary histograms

---

Fits are requested and there is sufficient data. Loop over specified crystals and performs fits to the amplitude distributions

Project 1D histogram of energy in this crystal

Fit function (xmin, xmax, nparameters) for this histogram

Estimate initial parameters from the histogram. For peak, use maximum bin in the allowed range

Fit range is just below peak to the histogram maximum

eta and constant are nominal values

Parameters to control iterations. dIter checks if we are stuck in a loop

Use a smaller fit range for high statistics histograms

---

Iterate from this point

Set the initial parameters

Fit

The lower fit range should correspond the specified fraction of the peak. Iterate if necessary.

Check if we are oscillating between two end points

Many iterations may mean we are stuck in a loop. Try a different end point.

Set the constant term to 0 if we are close to the limit

No more than specified number of iterations

---

..Manually calculate a more meaningful fit probability. Same as P option in fit, which cannot be used with L

only include this bin if meaningful

---

Fit status

No peak; normalization of Novo component is too small

poor fit, or relatively poor fit with too many iterations

parameter at limit

---

Find upper edge of Novosibirsk fit, if possible

Look for the fit to drop to specified fraction of peak.

bins on either side of this value

look for the target value between these two points

Fit was not successful despite sufficient statistics; find upper edge from bin contents

---

fill diagnostic histograms

1D summary histograms

Store histogram with fit

---

Interpret results of fit as expected energy or calibration constant

if no fit, set upperEdge to -1, so that output calib = -1 * abs(input calib)

Find expected energies from MC, if requested

Otherwise, calibration constant

---

Write output to DB if requested and successful

Store expected energies

Store calibration constants

---

Write out diagnostic histograms

Histograms containing values written to DB

---

Clean up histograms in case Algorithm is called again

---

Set the return code appropriately

Implements CalibrationAlgorithm.

Alias for prefix.

For convenience and less writing, we say developers to set this to default collector module name in constructor of base class. One can however use the dublets of collector+algorithm multiple times with different settings. To bind these together correctly, the prefix has to be set the same for algo and collector. So we call the setter setPrefix rather than setModuleName or whatever. This getter will work out of the box for default cases -> return the name of module you have to add to your path to collect data for this algorithm.

std::string m_outputName = "eclGammaGammaEAlgorithm.root"

private

..Parameters to control Novosibirsk fit to energy deposited in each crystal by mu+mu- events

file name for histogram output

Definition at line 121 of file eclGammaGammaEAlgorithm.h.

m_performFits

bool m_performFits = true

private

if false, input histograms are copied to output, but no fits are done

Definition at line 135 of file eclGammaGammaEAlgorithm.h.

m_prefix

std::string m_prefix {""}

privateinherited

The name of the TDirectory the collector objects are contained within.

Definition at line 388 of file CalibrationAlgorithm.h.

m_runsToInputFiles

std::map<Calibration::ExpRun, std::vector<std::string> > m_runsToInputFiles

privateinherited

Map of Runs to input files. Gets filled when you call getRunRangeFromAllData, gets cleared when setting input files again.

Definition at line 376 of file CalibrationAlgorithm.h.

m_storeConst

int m_storeConst = 0

private

controls which values are written to the database.

0 : store value found by successful fits, or -|input value| otherwise; -1 : do not store values 1 : store values if every fit for [cellIDLo,cellIDHi] was successful

Definition at line 138 of file eclGammaGammaEAlgorithm.h.

m_tRatioMaxHiStat

double m_tRatioMaxHiStat

private

Initial value:

=
        0.95

Fit range is adjusted so that fit at lower endpoint is between tRatioMin and tRatioMax of peak.

Definition at line 132 of file eclGammaGammaEAlgorithm.h.

m_tRatioMaxNom

double m_tRatioMaxNom = 0.70

private

Fit range is adjusted so that fit at lower endpoint is between tRatioMin and tRatioMax of peak.

Definition at line 129 of file eclGammaGammaEAlgorithm.h.

m_tRatioMinHiStat

double m_tRatioMinHiStat

private

Initial value:

=
        0.70

Fit range is adjusted so that fit at lower endpoint is between tRatioMin and tRatioMax of peak.

Definition at line 130 of file eclGammaGammaEAlgorithm.h.

m_tRatioMinNom

double m_tRatioMinNom

private

Initial value:

=

m_upperEdgeThresh

double m_upperEdgeThresh = 0.02

private

Upper edge is where the fit = upperEdgeThresh * peak value.

Definition at line 134 of file eclGammaGammaEAlgorithm.h.
