Detailed Description

A FunctorKey for CentroidResult.

This class makes it easy to copy centroids and their uncertainties to and from records, and provides a method to add the appropriate fields to a Schema.

Constructor & Destructor Documentation

CentroidResultKey() [1/3]

lsst::meas::base::CentroidResultKey::CentroidResultKey ( )

inline

Default constructor; instance will not be usuable unless subsequently assigned to.

Definition at line 107 of file CentroidUtilities.h.

CentroidResultKey() [2/3]

lsst::meas::base::CentroidResultKey::CentroidResultKey ( afw::table::PointKey< CentroidElement > const & centroid, afw::table::CovarianceMatrixKey< ErrElement, 2 > const & centroidErr )

inline

Construct from a pair of Keys.

Definition at line 110 of file CentroidUtilities.h.

CentroidResultKey() [3/3]

lsst::meas::base::CentroidResultKey::CentroidResultKey

(

afw::table::SubSchema const &

s

)

Construct from a subschema, assuming _x, _y, etc.

subfields

If a schema has "a_x", "a_y", etc. fields, this constructor allows you to construct a CentroidResultKey via:

CentroidResultKey k(schema["a"]);

Member Function Documentation

addFields()

CentroidResultKey lsst::meas::base::CentroidResultKey::addFields ( afw::table::Schema & schema, std::string const & name, std::string const & doc, UncertaintyEnum uncertainty )

static

Add the appropriate fields to a Schema, and return a CentroidResultKey that manages them.

Parameters

[in,out]	schema	Schema to add fields to.
[in]	name	Name prefix for all fields; "_x", "_y", etc. will be appended to this to form the full field names.
[in]	doc	String used as the documentation for the x and y fields.
[in]	uncertainty	Enum indicating which (if any) uncertainty values will be saved.

The unit for all fields will be pixels (pixels^2 for covariances).
