Detailed Description

A FunctorKey for FluxResult.

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

Constructor & Destructor Documentation

◆ FluxResultKey() [1/3]

lsst::meas::base::FluxResultKey::FluxResultKey ( )
inline

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

Definition at line 76 of file FluxUtilities.h.

76: _instFlux(), _instFluxErr() {}

◆ FluxResultKey() [2/3]

lsst::meas::base::FluxResultKey::FluxResultKey ( afw::table::Key< meas::base::Flux > const & instFlux,
afw::table::Key< meas::base::FluxErrElement > const & instFluxErr )
inline

Construct from a pair of Keys.

Definition at line 79 of file FluxUtilities.h.

82 : _instFlux(instFlux), _instFluxErr(instFluxErr) {}

◆ FluxResultKey() [3/3]

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

Construct from a subschema, assuming instFlux and instFluxErr subfields.

If a schema has "a_instFlux" and "a_instFluxErr" fields, this constructor allows you to construct a FluxResultKey via:

FluxResultKey k(schema["a"]);
A FunctorKey for FluxResult.

Definition at line 93 of file FluxUtilities.h.

94 : _instFlux(s["instFlux"]), _instFluxErr(s["instFluxErr"]) {}

Member Function Documentation

◆ addFields()

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

Add a pair of _instFlux, _instFluxErr fields to a Schema, and return a FluxResultKey that points to them.

Parameters
[in,out]schemaSchema to add fields to.
[in]nameName prefix for all fields; "_instFlux", "_instFluxErr" will be appended to this to form the full field names.
[in]docString used as the documentation for the fields.

The unit for both fields will be "count".

40 result._instFluxErr = schema.addField<meas::base::FluxErrElement>(
