TFile* JGIZMO::getFile ( const std::string &  file_name, const std::string &  option = "exist"  )

inline

Get TFile pointer corresponding to give file name.

The TFile pointer of an already opened file is recovered, else a new file is opened.
Note that the closure of the opened files should be done by the caller of this method.

Parameters

file_name	file name
option	TFile::Open option

Returns

pointer to TFile

void JGIZMO::setAxisLabels ( TAxis *  axis, const JModuleAddressMap &  memo  )

inline

Set axis with PMT address labels.

This methods sets the labels of the given axis to the sorted values of the PMT ring and position.
It should normally be called before filling of the corresponding histogram.
The filling should then be made with the textual representation of the PMT ring and position (i.e. JDETECTOR::JPMTPhysicalAddress::toString).

Alternatively, the filling can be made with the index of the PMT in the address map of the corresponding module (i.e. JDETECTOR::JModuleAddressMap::getIndex).
In that case, the method can be called before or after filling of the histogram.

Parameters

axis	axis
memo	module address map

void JGIZMO::setAxisLabels ( TH1 &  h1, const std::string  axis, const JModuleAddressMap &  memo  )

inline

Set axis labels with PMT addresses.

This methods sets the labels of the given axis to the sorted values of the PMT ring and position.
It should be called after filling of the corresponding histogram.
The filling should have been made with the PMT number (e.g. KM3NETDAQ::JDAQHit::getPMT).

Parameters

h1	histogram
axis	axis (x, X, y, Y, z, Z)
memo	module address map
