Excess Noise Astrometric Parameter Significance Classifier
Screen independent catalog excess-noise significance D(not noise/σsubstitution) against caller release-specific floor. Caller independently establishes frames, units, epoch, covariance and instrument context; not an identity, association or astrometric quality certification.
Description
Excess-noise significance summarizes one catalog diagnostic.
Excess-noise significance summarizes one catalog diagnostic.1
A chosen floor creates a review screen rather than a universal astrophysical classification. Use Excess Noise Astrometric Parameter Significance Classifier to evaluate the supplied inputs under the model explained below.
When to use Excess Noise Astrometric Parameter Significance Classifier
Use Excess Noise Astrometric Parameter Significance Classifier to evaluate the supplied inputs under the model explained below. Establish the units, measurement scope and model assumptions before entering values.
How to use Excess Noise Astrometric Parameter Significance Classifier and understand its results
- Establish the units, measurement scope and model assumptions before entering values.
- Enter Observed excess noise significance, Caller significance review floor using the field table and validation rules below, then run the tool.
- Read Caller excess noise review flag, Signed significance above floor; interpret the units, signs, ordering and unknown-value placeholders described below.
- Correct reported input errors and rerun. Apply successful results according to their specific meanings and check the assumptions before using them in a decision.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedExcessNoiseSignificance | Observed excess noise significance | number | Required; constraints below |
| callerSignificanceReviewFloor | Caller significance review floor | number | Required; constraints below |
Enter nonnegative significance and a positive caller review floor. Return significance−floor and flag significance≥floor. No built-in Gaia floor, stellar class or significance estimation is performed.
review=significance≥floor; signedAboveFloor=significance−floor Use the field order, units and branch conditions described above.
| Output field | Meaning | Value type |
|---|---|---|
| callerExcessNoiseReviewFlag | Caller excess noise review flag | boolean |
| signedSignificanceAboveFloor | Signed significance above floor | number |

}Limitations and assumptions
A chosen floor creates a review screen rather than a universal astrophysical classification. Apply the exact scope and assumptions explained above.
All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse arrays fail validation. Domain-specific bounds, alignments and supported tokens are explained above; extremely large inputs or outputs can also be rejected. Input errors differ from successful false results, empty match lists and unknown-evidence placeholders.
