The BEST contour plots of a Gloeocapsa colony on 15 x 15-cm limestone wafer in the 9090-15385 cm-1 band at a distance of 20 meters. The x and y axes in the plot represent distance on the surface of the substrate. The z axis (perpendicular to this screen) is the spectrum vector. The contour lines connect pixels with similar spectral vectors.
