std::string IFitResultROOT::dataDescription ( )

virtual

Textual description of data - this is a hint for the user how to find the data in the tree if he wanted to repeat the fit later and lost the pointer to his orignal data object.

PENDING: the contents and format of this string to be defined. PENDING: XML? stor name and path? ranges of DataPipe?

Implements AIDA::IFitResult.

const std::vector< double > & IFitResultROOT::errors ( ) const

virtual

Get the parabolic errors on the fitted parameters.

If a parameter was fixed or constrained the error is zero.
