Detailed Description

A FunctorKey for MagResult.

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

Constructor & Destructor Documentation

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

inline

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

Definition at line 154 of file FluxUtilities.h.

: _magKey(), _magErrKey() {}

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 164 of file FluxUtilities.h.

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

Member Function Documentation

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.

Definition at line 59 of file FluxUtilities.cc.

  {
    MagResultKey result;
    result._magKey = schema.addField<Mag>(schema.join(name, "mag"), "Magnitude");
    result._magErrKey = schema.addField<MagErrElement>(schema.join(name, "magErr"), "Error on magnitude");
    return result;
}

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

virtual

Get a MagResult from the given record.

Implements lsst::afw::table::OutputFunctorKey< MagResult >.

                                                                   {
    MagResult result = {record.get(_magKey), record.get(_magErrKey)};
    return result;
}

void lsst::meas::base::MagResultKey::set ( afw::table::BaseRecord &  record, MagResult const &  magResult  ) const

virtual

Set a MagResult in the given record.

Definition at line 74 of file FluxUtilities.cc.

                                                                                     {
    record.set(_magKey, magResult.mag);
    record.set(_magErrKey, magResult.magErr);
}

void lsst::meas::base::MagResultKey::set ( afw::table::BaseRecord &  record, std::pair< double, double > const &  magPair  ) const

virtual

Set a MagResult in the record given the result of afw::image::Calib::getMagnitude(double, double).

Definition at line 79 of file FluxUtilities.cc.

                                                                                                  {
    record.set(_magKey, magResult.first);
