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. References ExponentialResponseCurve(). Here is the call graph for this function:

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. Definition at line 154 of file SCTData/src/ResponseCurve.cpp. References invExpFn(), and SctData::ResponseCurve::ptr_inverse. Here is the call graph for this function:

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

It's inverse also used by root. Definition at line 181 of file SCTData/src/ResponseCurve.cpp. Referenced by getInverseFunction().
