Example:

// configuration of the TOF measurement algorithm:
datatools::utils::properties tof_meas_config;
tof_meas_config.store ("tof_eMgN_measurement.debug", true);
tof_meas_config.store ("tof_eMgN_measurement.tracking_name", "default");
tof_meas_config.store ("tof_eMgN_measurement.required_channel", "2e");

// setup the 2e TOF measurement algorithm:
tof_eMgN_measurement tof_meas;
tof_meas.init (tof_meas_config);

...
nemo3::ana_event the_event;
...
// load the event from a reader:
...
// apply the TOF measurement algorithm to the event:
tof_meas.do_measure (the_event);
...
//get the type of evt you want in a string :
internal_probability_property_name =
tof_eMgN_measurement::VALIDITY_PROPERTY_NAME_BEGIN + "e1g1"

Member Function Documentation

void nemo3::tof_eMgN_measurement::_compute_tof_properties ( ) [protected]

The private process,.

See also:: do_measurement

void nemo3::tof_eMgN_measurement::do_measurement ( ana_event & ) [virtual]

launch the main process

It looks the number of gammas and electrons with vertex and associated scins in the event, and calculate the probabilities of every electron-electron and gamma-gamma combinaison

then it keeps it in properties as in example, and in tof_col. The references numbers are from 0 to scin/track_number-1.

Implements nemo3::ana_event::i_measurement.

tof_tools& nemo3::tof_eMgN_measurement::get_tof_tools ( ) [inline]

get the used tof_tools

void nemo3::tof_eMgN_measurement::set_ECorr ( bool energy_loss_ )

if energy correction is used.
