Description
Label a supplied positive band-center wavelength and source.
Earth-science records distinguish depth signs, vertical datums, before-present ages, calibration factors and specimen definitions. Apparent porosity can be negative for inconsistent density inputs, and core recovery may exceed the drilled interval. Local labels and supplied transformations do not establish geological interpretation, physical validity or actual observation quality.
Label a supplied positive band-center wavelength and source.
When to use this tool
Use Earth Observation Band Center Label when you already have bandCode, wavelength, wavelengthUnit, source and need to label a supplied positive band-center wavelength and source.
How to use the tool and how it works
- Enter bandCode, wavelength, wavelengthUnit, source. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read label. Use the output convention below.
Require bandCode/unit/source nonempty and wavelength>0; format center wavelength with its supplied unit.1

}Limitations and assumptions
- No spectral response, effective wavelength, bandpass, sensor identity or calibration 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
Use verified survey, sample, sensor and timescale records with consistent units and reference frames. Apply the complete geological, hydrological or physical model when local density ratios, depth spans or calibration terms cannot establish the required interpretation.
