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; all RPC hits use the RPC resolution measured with the phi and z hits together)
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) added to EventT0 via addTemporaryEventT0, alongside the other detectors' values. The event T0 itself is never set or changed by this module.
The per-track result of each category as extra info of the muons in MuonListName: klmTrackT0<C>, klmTrackT0Err<C>, klmTrackNHits<C>, klmTrackSector<C>, klmTrackSection<C> for = BKLMScint, BKLMRPC, EKLMScint, and klmTrackT0All, klmTrackT0ErrAll over all categories of the track.
The per-event result of each category in EventExtraInfo: klmEventT0<C>, klmEventT0Err<C>.
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/scripts/KLMEventT0Validation.py, which reads the extra info above instead of recomputing it.

c_Input	This module is an input module (reads 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.)

Base class for Modules.
 
A module is the smallest building block of the framework.
A typical event processing chain consists of a Path containing
modules. By inheriting from this base class, various types of
modules can be created. To use a module, please refer to
:func:`Path.add_module()`.  A list of modules is available by running
``basf2 -m`` or ``basf2 -m package``, detailed information on parameters is
given by e.g. ``basf2 -m RootInput``.
 
The 'Module Development' section in the manual provides detailed information

Sets a conditional sub path which will be executed after this
module if the return value set in the module passes the given ``expression``.
 
Modules can define a return value (int or bool) using ``setReturnValue()``,
which can be used in the steering file to split the Path based on this value, for example
 
>>> module_with_condition.if_value("<1", another_path)
 
In case the return value of the ``module_with_condition`` for a given event is
less than 1, the execution will be diverted into ``another_path`` for this event.
 
You could for example set a special return value if an error occurs, and divert
the execution into a path containing :b2:mod:`RootOutput` if it is found;
saving only the data producing/produced by the error.
 
After a conditional path has executed, basf2 will by default stop processing
the path for this event. This behaviour can be changed by setting the
``after_condition_path`` argument.
 
Parameters:
  expression (str): Expression to determine if the conditional path should be executed.
      This should be one of the comparison operators ``<``, ``>``, ``<=``,
      ``>=``, ``==``, or ``!=`` followed by a numerical value for the return value

◆ getFileNames()

virtual std::vector< std::string > getFileNames ( bool outputFiles )

inlinevirtualinherited

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.

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

A simplified version to add a condition to the module.

Please note that successive calls of this function will add more than one condition to the module. If more than one condition results in true, only the last of them will be used.

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

path	Shared pointer to the Path which will be executed if the return value is false.
afterConditionPath	What to do after executing 'path'.

Definition at line 85 of file Module.cc.

{
  if_value("<1", path, afterConditionPath);

Please note that successive calls of this function will add more than one condition to the module. If more than one condition results in true, only the last of them will be used.

See https://xwiki.desy.de/xwiki/rest/p/a94f2 or ModuleCondition for a description of the syntax.

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.

Parameters

expression	The expression of the condition.
path	Shared pointer to the Path which will be executed if the condition is evaluated to true.
afterConditionPath	What to do after executing 'path'.

Definition at line 79 of file Module.cc.

{
