Class Documentation

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

An ellipse core for the semimajor/semiminor axis and position angle parametrization (a,b,theta).

Public Types

enum ParameterEnum

Values:

A = 0

B = 1

THETA = 2

Public Functions

double const getA() const

void setA(double a)

double const getB() const

void setB(double b)

std::shared_ptr<Axes> clone() const

Deep copy the ellipse core.

std::string getName() const

Return a string that identifies this parametrization.

void normalize()

Put the parameters into a “standard form”, if possible, and throw InvalidParameterError if they cannot be normalized.
