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.

For convenience and less writing, we say developers to set this to default collector module name in constructor of base class.

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.

{
  // Construct an EventMetaData object but NOT in the Datastore
  EventMetaData emd(event, run, experiment);
  // Explicitly update while avoiding registering a Datastore object
  DBStore::Instance().update(emd);
  // Also update the intra-run objects to the event at the same time (maybe unnecessary...)
  DBStore::Instance().updateEvent(event);

correctForward

bool correctForward

Flag to update default gains in forward region due to low statistics.

Definition at line 51 of file PXDAnalyticGainCalibrationAlgorithm.h.

forceContinue

bool forceContinue

Force continue in low statistics runs instead of returning c_NotEnoughData.

Definition at line 42 of file PXDAnalyticGainCalibrationAlgorithm.h.

m_allExpRun

const ExpRun m_allExpRun = make_pair(-1, -1)

staticprivateinherited

allExpRun

Definition at line 364 of file CalibrationAlgorithm.h.

m_boundaries

std::vector<Calibration::ExpRun> m_boundaries

protectedinherited

When using the boundaries functionality from isBoundaryRequired, this is used to store the boundaries. It is cleared when.

Definition at line 261 of file CalibrationAlgorithm.h.

m_data

ExecutionData m_data

privateinherited

Data specific to a SINGLE execution of the algorithm. Gets reset at the beginning of execution.

Definition at line 382 of file CalibrationAlgorithm.h.

m_description

std::string m_description {""}

privateinherited

Description of the algorithm.

Definition at line 385 of file CalibrationAlgorithm.h.

m_granularityOfData

std::string m_granularityOfData

privateinherited

Granularity of input data. This only changes when the input files change so it isn't specific to an execution.

Definition at line 379 of file CalibrationAlgorithm.h.

m_inputFileNames

std::vector<std::string> m_inputFileNames

privateinherited

List of input files to the Algorithm, will initially be user defined but then gets the wildcards expanded during execute()

Definition at line 373 of file CalibrationAlgorithm.h.

m_jsonExecutionInput

nlohmann::json m_jsonExecutionInput = nlohmann::json::object()

privateinherited

Optional input JSON object used to make decisions about how to execute the algorithm code.

Definition at line 397 of file CalibrationAlgorithm.h.

m_jsonExecutionOutput

nlohmann::json m_jsonExecutionOutput = nlohmann::json::object()

privateinherited

Optional output JSON object that can be set during the execution by the underlying algorithm code.

Definition at line 403 of file CalibrationAlgorithm.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_requestedBoundaries

std::vector<Calibration::ExpRun> m_requestedBoundaries

private

During findPayloadBoundaries and isBoundaryRequired this is used to define the boundaries we want.

Definition at line 95 of file PXDAnalyticGainCalibrationAlgorithm.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.

minClusters

int minClusters

Minimum number of collected clusters for estimating gains.

Definition at line 36 of file PXDAnalyticGainCalibrationAlgorithm.h.

safetyFactor

float safetyFactor

Safety factor for determining whether the collected number of clusters is enough.

Definition at line 39 of file PXDAnalyticGainCalibrationAlgorithm.h.

strategy

int strategy

strategy to used for gain calibration, 0 for medians, 1 for landau fit

Definition at line 45 of file PXDAnalyticGainCalibrationAlgorithm.h.

useChargeRatioHistogram

bool useChargeRatioHistogram

Flag to use histogram of charge ratio (relative to expected MPV)

Definition at line 48 of file PXDAnalyticGainCalibrationAlgorithm.h.
