Member Function Documentation

auto_ptr< ResponseCurve > SctData::GrilloResponseCurve::create  )  const throw () [virtual]
 

Method used by IO refresh to create from a general mode a mode of the appropriate type.

Returns:
a new object of the derived class type.

Implements SctData::ResponseCurve.

Definition at line 183 of file ResponseCurve.cpp.

virtual string SctData::GrilloResponseCurve::getCurveName  )  const throw () [inline, virtual]
 

idendifier so that IO can find the right curve

Reimplemented from SctData::ResponseCurve.

Definition at line 146 of file SCTData/src/ResponseCurve.h.

double SctData::GrilloResponseCurve::getGain const double  charge  )  const throw () [virtual]
 

Given a TF1 and a charge point, return the gain.

Parameters:
charge The charge for which the gain is wanted.
Returns:
The gain.

Implements SctData::ResponseCurve.

Definition at line 187 of file ResponseCurve.cpp.

shared_ptr< TF1 > SctData::GrilloResponseCurve::getInverseFunction  )  const throw (LogicError) [virtual]
 

Get a TF1 that represents the inverse function.

(i.e. charge as a function of threshold)

Exceptions:
LogicError if TF1 can't be made;

Implements SctData::ResponseCurve.

Definition at line 170 of file ResponseCurve.cpp.

double SctData::GrilloResponseCurve::grilloFn double *  x,
double *  par
throw () [static]

double SctData::GrilloResponseCurve::invGrilloFn double *  x,
double *  par
throw () [static]
 

It's inverse also used by root.
