DESCRIPTION = "The spatial resolution of the telescopic data in this archive depends on the aperture used and the telescope configuration. Most data are for areas 5-10 km in diameter. For small lunar features the measured spectrum also contains radiation from surrounding soil. An example of this relation is shown in this figure, CLEMSPEC.GIF, where the telescopic spectrum for a small crater in Mare Serenitatis (MSA: located at 19.5 degrees north, 24.5 degrees east) is compared with multispectral data from Clementine. All the Clementine spectra are centered on the crater, but are sampled at 1, 3, 5, 7, 9, 11,13, 15, 17, and 19 kilometers (square). The aperture used for this telescopic data was estimated to cover about a 5 km region, a value consistent with the Clementine data." END_OBJECT = GIF_DOCUMENT END
