Detailed Description

Estimate per-event T0 using KLM (BKLM scint, BKLM RPC, EKLM scint).

Inputs:

  • ParticleList (tracks with relations to KLMHit2d and ExtHit)
  • KLM conditions (time constants, cable delays, channel status, calibrated per-hit resolution)
  • BKLM/EKLM geometry for propagation distances and transforms

Outputs:

  • A single KLM EventT0 component per event (combination of all available categories: BKLM-Scint, BKLM-RPC, EKLM-Scint) saved via addTemporaryEventT0 and setEventT0.
  • Monitoring histograms under histogramDirectoryName with subdirectories: per_track/ — per-track T0 by detector category per_event/ — per-event track-averages and SEMs final/ — final combined EventT0 and source audit

Validation histograms (pulls, residuals, dimuon ΔT0, pairwise sector analysis, cross-detector ΔT0) are handled separately by KLMEventT0ValidationModule in klm/validation/KLMEventT0Validation.py.

Each module can be tagged with property flags, which indicate certain features of the module.

Enumerator
c_Input 

This module is an input module (reads data).

c_Output 

This module is an output module (writes data).

c_ParallelProcessingCertified 

This module can be run in parallel processing mode safely (All I/O must be done through the data store, in particular, the module must not write any files.)

c_HistogramManager 

This module is used to manage histograms accumulated by other modules.

c_InternalSerializer 

This module is an internal serializer/deserializer for parallel processing.

c_TerminateInAllProcesses 

When using parallel processing, call this module's terminate() function in all processes().

This will also ensure that there is exactly one process (single-core if no parallel modules found) or at least one input, one main and one output process.

c_DontCollectStatistics 

No statistics is collected for this module.

385A module is the smallest building block of the framework.

439Sets a conditional sub path which will be executed after this
440module if the return value set in the module passes the given ``expression``.
441
442Modules can define a return value (int or bool) using ``setReturnValue()``,
443which can be used in the steering file to split the Path based on this value, for example
444
445>>> module_with_condition.if_value("<1", another_path)
446
447In case the return value of the ``module_with_condition`` for a given event is
448less than 1, the execution will be diverted into ``another_path`` for this event.
449
450You could for example set a special return value if an error occurs, and divert
451the execution into a path containing :b2:mod:`RootOutput` if it is found;
452saving only the data producing/produced by the error.
453
454After a conditional path has executed, basf2 will by default stop processing
455the path for this event. This behaviour can be changed by setting the
456``after_condition_path`` argument.

458Parameters:
459 expression (str): Expression to determine if the conditional path should be executed.
460 This should be one of the comparison operators ``<``, ``>``, ``<=``,

◆ getFileNames()

Return a list of output filenames for this modules.

This will be called when basf2 is run with "--dry-run" if the module has set either the c_Input or c_Output properties.

If the parameter outputFiles is false (for modules with c_Input) the list of input filenames should be returned (if any). If outputFiles is true (for modules with c_Output) the list of output files should be returned (if any).

If a module has sat both properties this member is called twice, once for each property.

The module should return the actual list of requested input or produced output filenames (including handling of input/output overrides) so that the grid system can handle input/output files correctly.

This function should return the same value when called multiple times. This is especially important when taking the input/output overrides from Environment as they get consumed when obtained so the finalized list of output files should be stored for subsequent calls.

Reimplemented in RootInputModule, RootOutputModule, and StorageRootOutputModule.

◆ if_false()

void if_false ( const std::shared_ptr< Path > & path,

Please be careful: Avoid creating cyclic paths, e.g. by linking a condition to a path which is processed before the path where this module is located in.

It is equivalent to the if_value() method, using the expression "<1". This method is meant to be used together with the setReturnValue(bool value) method.

Parameters
pathShared pointer to the Path which will be executed if the return value is false.
afterConditionPathWhat to do after executing 'path'.
