class Quadrupole : public lsst::afw::geom::ellipses::BaseCore

An ellipse core with quadrupole moments as parameters.

Public Types

enum ParameterEnum

Values:

IXX = 0

IYY = 1

IXY = 2

typedef Eigen::Matrix<double, 2, 2, Eigen::DontAlign> Matrix

Matrix type for the matrix representation of Quadrupole parameters.
