..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

---

Clean up existing histograms if necessary

---

Histograms containing the data collected by eclMuMuECollectorModule

---

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.

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 histogram low edge plus a few bins to peak + 2.5*effective sigma

eta and constant are nominal values

Constant from lower edge of plot

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

---

Iterate from this point

Set the initial parameters

Fix eta if this is an endcap crystal, or if findExpValues==false

Fit

The upper fit range should correspond to 20-25% 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

---

Fit status

No peak; normalization of Novo component is too small

poor fit, or relatively poor fit with too many iterations

parameter at limit

fill diagnostic histograms

1D summary histograms

Store histogram with fit

---

Interpret results of fit as expected energy or calibration constant

if the fit is not successful, set peakE 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.

checkPyExpRun()

bool checkPyExpRun ( PyObject *  pyObj )

inherited

Checks that a PyObject can be successfully converted to an ExpRun type.

Checks if the PyObject can be converted to ExpRun.

Definition at line 21 of file CalibrationAlgorithm.cc.

convertPyExpRun()

ExpRun convertPyExpRun ( PyObject *  pyObj )

inherited

Performs the conversion of PyObject to ExpRun.

Converts the PyObject to an ExpRun. We've preoviously checked the object so this assumes a lot about the PyObject.

Definition at line 63 of file CalibrationAlgorithm.cc.

execute()

EResult execute ( std::vector< Calibration::ExpRun >  runs = {}, int  iteration = 0, IntervalOfValidity  iov = IntervalOfValidity()  )

inherited

Runs calibration over vector of runs for a given iteration.

You can also specify the IoV to save the database payload as. By default the Algorithm will create an IoV from your requested ExpRuns, or from the overall ExpRuns of the input data if you haven't specified ExpRuns in this function.

No checks are performed to make sure that a IoV you specify matches the data you ran over, it simply labels the IoV to commit to the database later.

getCollectorName()

std::string getCollectorName ( ) const

inlineinherited

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 algorihtm.

setInputFileNames() [1/2]

void setInputFileNames ( PyObject *  inputFileNames )

Set the input file names used for this algorithm from a Python list.

Set the input file names used for this algorithm and resolve the wildcards.

setInputFileNames() [2/2]

void setInputFileNames ( std::vector< std::string >  inputFileNames )

Set the input file names used for this algorithm.

Set the input file names used for this algorithm and resolve the wildcards.
