Constructor & Destructor Documentation

MagResultKey() [1/2]

lsst::meas::base::MagResultKey::MagResultKey ( )

inline

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

Definition at line 150 of file FluxUtilities.h.

: _magKey(), _magErrKey() {}

MagResultKey() [2/2]

lsst::meas::base::MagResultKey::MagResultKey ( afw::table::SubSchema const & s )

inline

Construct from a subschema, assuming mag and magErr subfields.

If a schema has "a_mag" and "a_magErr" fields, this enables construction of a MagResultKey via:

MagResultKey k(schema["a"]);

Definition at line 160 of file FluxUtilities.h.

: _magKey(s["mag"]), _magErrKey(s["magErr"]) {}

Member Function Documentation

addFields()

MagResultKey lsst::meas::base::MagResultKey::addFields ( afw::table::Schema & schema, std::string const & name )

static

Add a pair of _mag, _magErr fields to a Schema, and return a MagResultKey that points to them.

Parameters

[in,out]	schema	Schema to add fields to.
[in]	name	Name prefix for all fields; "_mag", "_magErr" will be appended to this to form the full field names.

get()

MagResult lsst::meas::base::MagResultKey::get ( afw::table::BaseRecord const & record ) const
