Detailed Description

This class represents the points in a scan.

It contains methods to get the number of events, the number of error events and the variable value for each point. There are also some utility methods to get "bin" values for use in setting histogram axes and to set a TAxis directly.

Constructor & Destructor Documentation

SctData::ScanPoints::ScanPoints (  const unsigned  nPoints,
const float *  points,
const unsigned *  nEvents,
const unsigned *  nErrorEvents
)  throw ()
 

Create a ScanPoints from data that is already known.

Parameters:
the number of points
pointer to float[nPoints] : scan-point values
pointer to unsigned[nPoints] : numbers of events
pointer to unsigned[nPoints] : numbers of error events
Note:
does not take ownership of arguments - copies them;
