Public Member Functions | |
CModelStageResult () | |
Public Attributes | |
std::shared_ptr< Model > | model |
Model object that defines the parametrization (defined fully by Control struct) | |
std::shared_ptr< Prior > | prior |
Bayesian priors on the parameters (defined fully by Control struct) | |
std::shared_ptr< OptimizerObjective > | objfunc |
Objective class used by the optimizer. | |
std::shared_ptr< UnitTransformedLikelihood > | likelihood |
Object used to evaluate models and compare to data. | |
Scalar | instFlux |
Flux measured from just this stage fit. | |
Scalar | instFluxErr |
Flux uncertainty from just this stage fit. | |
Scalar | instFluxInner |
Flux measured strictly within the fit region (no extrapolation). | |
Scalar | objective |
Value of the objective function at the best fit point: chisq/2 - ln(prior) | |
Scalar | time |
Time spent in this fit in seconds. | |
afw::geom::ellipses::Quadrupole | ellipse |
Best fit half-light ellipse in pixel coordinates. | |
ndarray::Array< Scalar const, 1, 1 > | nonlinear |
Opaque nonlinear parameters in specialized units. | |
ndarray::Array< Scalar const, 1, 1 > | amplitudes |
Opaque linear parameters in specialized units. | |
ndarray::Array< Scalar const, 1, 1 > | fixed |
Opaque fixed parameters in specialized units. | |
afw::table::BaseCatalog | history |
Trace of the optimizer's path, if enabled by diagnostic options. | |
std::bitset< N_FLAGS > | flags |
Array of flags. | |
Result object for a single nonlinear fitting stage of the CModel algorithm.
Flags for a single CModel stage (note that there are additional flags for the full multi-stage fit)
Enumerator | |
---|---|
FAILED | General flag, indicating whether the flux for this stage can be trusted. |
TR_SMALL | Whether convergence was due to the optimizer trust region getting too small (not a failure!) |
MAX_ITERATIONS | Whether the optimizer exceeded the maximum number of iterations. Indicates a suspect fit, but not necessarily a bad one (implies FAILED). |
NUMERIC_ERROR | Optimizer encountered a numerical error (something likely went to infinity). Result will be unusable; implies FAILED. |
BAD_REFERENCE | Reference fit failed, so forced fit will fail as well. |
NO_FLUX | No flux was measured. |
N_FLAGS | Non-flag counter to indicate the number of flags. |
