Enumeration Type Documentation

UncertaintyEnum

enum lsst::meas::base::UncertaintyEnum

An enum used to specify how much uncertainty information measurement algorithms provide.

Currently, only ResultMappers (not Results) make use of these distinctions; Result structs always have data members that could hold the full-covariance, but may set some of these to NaN.

Enumerator
NO_UNCERTAINTY	Algorithm provides no uncertainy information at all.
SIGMA_ONLY	Only the diagonal elements of the covariance matrix are provided.
FULL_COVARIANCE	The full covariance matrix is provided.

Definition at line 43 of file constants.h.

                     {
    NO_UNCERTAINTY = 0,  
    SIGMA_ONLY = 1,      
    FULL_COVARIANCE = 2

makeShapeTransformMatrix()

ShapeTrMatrix lsst::meas::base::makeShapeTransformMatrix

(

geom::LinearTransform const &

xform

)

Construct a matrix suitable for transforming second moments.

Given an LinearTransform which maps from positions (x, y) to (a, d), returns a 3-by-3 matrix which transforms (xx, yy, xy) to (aa, dd, ad).

That is, given an input transform described by the matrix

| A11 | A12 | | A21 | A22 |

we return the matrix

| A11*A11 | A12*A12 | 2*A11*A12 | | A21*A21 | A22*A22 | 2*A21*A22 | | A11*A21 | A12*A22 | A11*A22 + A12*A21 |

Parameters

xform

LinearTransform describing the coordinate mapping

Returns

A 3-by-3 transformation matrix for the second order moments
