Lists the six black/grey weathered road-asphalt specimens and their individual emissivities.

Assessment findings

Namesupported
The name identifies the black/grey weathered road-asphalt specimen group A001-A006.
Targetsupported
All six inputs are road-asphalt specimens, matching land_cover.paved.
Valuessupported
The stored value is exactly the unweighted mean of 0.96, 0.94, 0.94, 0.94, 0.93 and 0.91.
Sourcesupported
The mean is a database calculation not printed by Kotthaus et al.; source unreferenced avoids crediting the publication with the derived value while the six located table rows preserve its evidence.
Placesupported
The six specimens belong to the London Urban Micromet data Archive material collection.
Representativenesssupported
The value is an unweighted mean of six selected physical specimens, so site is the supported scope; the spectral library does not establish a London-wide sampling design.
issue #246
Methodsupported
The record is the component-wise arithmetic mean of six source-tabulated inputs.
Identitysupported
The exact arithmetic and shared material description identify A001-A006 as the inputs.
issue #245

Scientific note

Kotthaus et al. publish six measured emissivities, not the stored mean. The mean remains unchanged and is represented as an internal calculation over explicitly located source-table inputs; its supported reach is the selected London specimen group, not the city as a whole.
