The Bloomsburg University Goniometer (BUG) was used to make bidirectional 
reflectance distribution function (BRDF) measurements of Apollo soil samples. 
Measurements were made at wavelengths of 453, 550, 751, and 952 nanometers.

The archive consists of 6 tabular data files, each with an accompanying 
detached PDS label. Columns are incidence angle, emission angle, azimuth 
angle, phase angle (all in degrees, i and e are measured from nadir), and 
corrected radiance factor at four different center wavelengths.

Please also see CATALOG/BUGAPOLLO_DS.CAT for additional sample and data set 
acquisition information.
