Tidal Friction Day Lengthening Rate Lookup
Audit observed day-lengthening against caller independently verified epoch/method tidal-friction reference; no extrapolated rotation forecast. Independently verified caller edition/site/specimen reference, no fabricated table. Caller independently establishes units, regime, calibration and applicability; this does not establish design-code compliance, authenticity, operational safety, treatment efficacy or a validated forecast.
Description
Tidal contributions to day-length change depend on the epoch and estimation method.
Tidal contributions to day-length change depend on the epoch and estimation method.1
This audit retrieves your exact numeric reference and retains the signed observed-minus-reference difference.
When to use Tidal Friction Day Lengthening Rate Lookup
Use this tool to compare an observation with its exact numeric reference. Match the observation interval, units, datum, coordinate signs and model regime.
How to use Tidal Friction Day Lengthening Rate Lookup and understand its results
- Match the observation interval, units, datum, coordinate signs and model regime.
- Enter callerDayLengtheningIds, callerDayLengtheningValues, queryDayLengtheningId, observedDayLengtheningValue, using the field meanings and rules below, then run the tool.
- Read callerMatchedReferenceValue, signedObservedMinusReference. Inspect nested result fields where present, and review unknown records separately from known matches.
- Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| callerDayLengtheningIds | Caller day lengthening ids | list of string | Required |
| callerDayLengtheningValues | Caller day lengthening values | list of number | Required |
| queryDayLengtheningId | Query day lengthening id; use the exact reference token or coordinate domain stated below | string | Required |
| observedDayLengtheningValue | Observed day lengthening value | number | Required |
Supply nonempty aligned unique nonblank reference keys and finite reference numbers. Query one exact existing key and provide a finite observation in the same units. Return the matched number and observed-minus-reference; signed inputs are accepted and no special physical range is inferred. Unknown keys fail.
reference=values[indexOf(keys,query)]; difference=observed−reference Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| callerMatchedReferenceValue | Caller matched reference value | number |
| signedObservedMinusReference | Signed observed minus reference; preserve the subtraction order and sign defined in the mechanics | number |

} Limitations and assumptions
The stated observation or model covers only the supplied record and reference regime. It does not fill missing measurements, supply uncertainty estimates or produce a validated forecast. Reference records and their claimed verification are supplied by the caller; the tool does not retrieve or verify them.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Lists and matrices must be dense, without missing cells. Numeric lists allow at most 10000 entries; ordinary string lists allow at most 128 strings of 128 UTF-16 units each; numeric matrices allow at most 128 rows and 128 columns, subject to narrower requirements above.
