Detailed Description

This class represents the normal exponential fit to the response curve.

The fit function is: [2]+ [0]/(1 + exp(-x/[1])).

Member Function Documentation

auto_ptr< ResponseCurve > SctData::ExponentialResponseCurve::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 167 of file SCTData/src/ResponseCurve.cpp.

double SctData::ExponentialResponseCurve::expFn double *  x,
double *  par
throw () [static]
 

The function used by Root for the exponential.

Definition at line 178 of file SCTData/src/ResponseCurve.cpp.

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

idendifier so that IO can find the right curve

Reimplemented from SctData::ResponseCurve.

Definition at line 125 of file SCTData/src/ResponseCurve.h.

double SctData::ExponentialResponseCurve::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 171 of file SCTData/src/ResponseCurve.cpp.

shared_ptr< TF1 > SctData::ExponentialResponseCurve::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.

double SctData::ExponentialResponseCurve::invExpFn double *  x,
double *  par
throw () [static]
 

It's inverse also used by root.
