Description
Calculate a target-pollen share under an unidentified-count policy.
Botanical observations distinguish specimen provenance, sampling states, germination records, image area and category vocabularies. Excluded observations differ from failed germination, and a pixel-area calibration must use an area ratio rather than a length ratio. Source-qualified labels preserve reported identifications without confirming them.
Calculate a target-pollen share under an unidentified-count policy.
When to use this tool
Use Pollen Count Denominator Flag when you already have identifiedCount, unidentifiedCount, includeUnidentified, targetCount and need to calculate a target-pollen share under an unidentified-count policy.
How to use the tool and how it works
- Enter identifiedCount, unidentifiedCount, includeUnidentified, targetCount. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read denominator, targetFraction, defined. Inspect defined before interpreting the associated values.
Require safe nonnegative counts and target<=identified; denominator=identified+optionalUnidentified. Return target/denominator or zero with defined=false when denominator=0.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| identifiedCount | Identified Count | Required. Safe integer; minimum 0. |
| unidentifiedCount | Unidentified Count | Required. Safe integer; minimum 0. |
| includeUnidentified | Include Unidentified | Required. Boolean. |
| targetCount | Target Count | Required. Safe integer; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| denominator | Identified count plus unidentified count only when requested; safe integer total required. | Required. Safe integer. |
| targetFraction | Target Fraction | Required. Finite number. |
| defined | Defined | Required. Boolean. |

} Limitations and assumptions
- Unsafe denominators are rejected. No pollen, taxon, observation completeness, sampling comparability or biological abundance is verified.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Inspect the original specimens, observation logs, calibrated images and taxonomic sources. Use the complete survey or experimental method for biological interpretation; local fractions and record checks do not infer unobserved states or mechanisms.
