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. |
