TITLE: Flower Pansy-1 Yellow DESCRIPT
DOCUMENTATION_FORMAT: PLANT
SAMPLE_ID: Pansy-1
PLANT_TYPE: Domesticated Plant
PLANT: Pansy
LATIN_NAME: Viola sp.
COLLECTION_LOCALITY: Lakewood, Colorado
ORIGINAL_DONOR:
SAMPLE_DESCRIPTION:
Average reflectance for a yellow flower of the pansy plant (Viola sp.). The small flowers of the plant were 4-6 cm in diameter. The pansy plant was growing in a domestic garden.
The spectra were collected with the head of the spectrometer pointed approximately 45 degrees off-nadir, approximately 2-3 centimeters from the surface of the flower. The spectrometer head (bare fiber optic) was moved over different parts of the flower petals in order to compute the average reflectance for the flower from any variations in the individual petals. This average spectrum was computed from 12 individual recorded spectra (each recorded spectrum was an average of 60 measurements).
Sky conditions during the measurement were cloud-free.
