Thinning Light Test Pass-Fail Checker
Compare independently measured transmitted-light observations with matched caller reference bands; not a destructive test. Missing observations remain explicit. Caller independently verifies observations, reference edition, units and applicability; not a grading-service certificate, authentication, conservation treatment, actual market price or legal/insurance entitlement.
Description
A thin area may be recorded through a transmission observation interpreted against a matched comparison band.
A thin area may be recorded through a transmission observation interpreted against a matched comparison band.1
This checker evaluates supplied measurements and known flags, keeping missing assessments separate from measured deviations.
When to use Thinning Light Test Pass-Fail Checker
Use this tool when you need to review known observations against explicit inclusive bands. Prepare independently verified observations, reference edition/context, and matching units or currency basis.
How to use Thinning Light Test Pass-Fail Checker and understand its results
- Prepare independently verified observations, reference edition/context, and matching units or currency basis.
- Enter observedTransmission, callerTransmissionLower, callerTransmissionUpper, knownTransmissionFlags, following the field table and calculation rules below, then run the tool.
- Read signedKnownMargins, knownReviewIndices, unknownIndices. For result objects, inspect the nested output fields below, including any missing evidence or selected indices.
- Correct any input issues and run again. Before using a successful result, review its units, signs, evidence coverage, and stated model or reference assumptions.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedTransmission | Observed transmission | list of number | Required |
| callerTransmissionLower | Caller transmission lower | list of number | Required |
| callerTransmissionUpper | Caller transmission upper | list of number | Required |
| knownTransmissionFlags | Known transmission flags; binary 1 means assessed and 0 means unknown. | list of number | Required |
Enter nonempty aligned observed values, caller lower/upper bounds, and binary known flags. Require lower≤upper for every row, even an unknown one. For a known value return min(value−lower,upper−value): positive inside, zero on a boundary, and negative outside. Only known values strictly outside the inclusive band enter knownReviewIndices. Unknown rows receive a zero placeholder and their separate unknownIndices, so an unknown zero margin is not passing evidence.
margin_i=known_i?min(observed_i−lower_i,upper_i−observed_i):0 Read these symbols with the field meanings and branch or reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| signedKnownMargins | Minimum signed distance to the two inclusive bounds for known observations; zero placeholder for unknown observations. | list of number |
| knownReviewIndices | Zero-based input positions that are known and strictly outside the inclusive reference band. | list of number |
| unknownIndices | Zero-based input positions without a known observation; inspect before interpreting zero placeholders. | list of number |

}Limitations and assumptions
The observation method, units, and appropriate bounds come from the supplied records. Unknown observations remain unassessed, and numeric band agreement does not authenticate an item or establish a certified grade.
Missing required fields, unknown fields, wrong types, and violated calculation rules return input issues. Numeric values must be finite; nonfinite numeric outputs are rejected. Arrays must be dense, with no missing cells. Numeric lists allow at most 10000 entries, subject to smaller tool-specific bounds above.
Alternative or Complementary methods
For a related task, use Sound Stamp Binary Quality Gate Checker: A sound-stamp assessment depends on which faults were actually inspected. This gate distinguishes an observed fault, a fully assessed absence of the listed faults, and an incomplete assessment. For a complementary step, use Paper Thickness micrometre Range Class Rater: Paper thickness can be interpreted under an issue-specific or reference-specific scale. This rater interpolates a supplied thickness classification curve without assuming universal thin, medium, and thick boundaries.
