Geology Luminescence Equivalent Dose Calculator
Equivalent dose from independently fixed same-aliquot normalized luminescence growth curve; saturation, bleaching and dose-rate age conversion not inferred. Conditional independently matched piecewise-linear calibration, no extrapolation. Caller independently establishes matching units, evidence, method edition and applicability; output is not compliance, diagnosis, work-safety approval, geological identity or validated hazard prediction.
Description
An equivalent-dose interpretation relies on a laboratory response calibration with an appropriate measurement protocol.
An equivalent-dose interpretation relies on a laboratory response calibration with an appropriate measurement protocol.1
A linear interpolation of submitted knots reports a conditional response and local secant slope without modeling dose uncertainty or saturation. Use this tool to interpolate the supplied calibration and inspect its local slope.
When to use Geology Luminescence Equivalent Dose Calculator
Use this tool to interpolate the supplied calibration and inspect its local slope. Establish the measurement units, sampled interval, calibration or model edition and geological assumptions before entering data.
How to use Geology Luminescence Equivalent Dose Calculator and understand its results
- Establish the measurement units, sampled interval, calibration or model edition and geological assumptions before entering data.
- Enter observedLuminescenceGrowthSignalCoordinates, callerMatchedLuminescenceGrowthSignalResponses, queryLuminescenceGrowthSignalCoordinate, using the field meanings and rules below, then run the tool.
- Read interpolatedResponse, localObservedSlope. Interpret the fields using their units, signs and evidence conventions below.
- If input validation fails, correct the reported field and run again. Before applying the result, check reference scope, model assumptions and any missing evidence or placeholder values.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedLuminescenceGrowthSignalCoordinates | Observed luminescence growth signal coordinates | list of number | Required |
| callerMatchedLuminescenceGrowthSignalResponses | Caller matched luminescence growth signal responses | list of number | Required |
| queryLuminescenceGrowthSignalCoordinate | Query luminescence growth signal coordinate | number | Required |
Enter at least two aligned finite calibration coordinates and responses. Coordinates must be strictly increasing, and the query must be within the first and last coordinates, including endpoints. Interpolate the response linearly on its enclosing segment and return the response plus that segment's slope. At an internal knot the slope uses the segment to its right; at the last knot it uses the last segment. There is no extrapolation, curve fitting or built-in calibration, and response knots need not be monotonic. Independently establish coordinate and response units and applicable calibration scope.
y(q)=y_j+(q−x_j)×(y_(j+1)−y_j)/(x_(j+1)−x_j); localSlope=(y_(j+1)−y_j)/(x_(j+1)−x_j) Use the exact units, boundary rules, ordering and missing-evidence conventions above.
| Output field | Meaning | Value type |
|---|---|---|
| interpolatedResponse | Piecewise-linear response at the query, in the caller response unit | number |
| localObservedSlope | Enclosing segment response change per coordinate unit, using the knot-side convention above | number |

}Limitations and assumptions
Results are confined to the supplied calibration interval. The tool does not establish a valid physical calibration, propagate measurement uncertainty or guarantee that linear segments represent the underlying process.
All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse evidence arrays fail validation; the specific bounds and alignment requirements are stated above. Extremely large inputs or outputs can also be rejected. An input error is distinct from a successful result reporting false, no matches or missing evidence.
