Detailed Description

template<class T, class ErrorWeightType>
class GlobalErrorBase< T, ErrorWeightType >

Templated class representing a symmetric 3*3 matrix describing, according to the ErrorWeightType tag, a (cartesian) covariance matrix or the weight matrix (the inverse of the covariance matrix).

• To have a covariance matrix, the ErrorMatrixTag has to be used, and a typedef is available as GlobalError
• To have a weight matrix, the WeightMatrixTag has to be used, and a typedef is available as Globalweight

The typedefs should be used in the code.
