   Data Set Overview
   =================
     The data contained in this archive are a survey of the spectra of 
     small fresh craters on the lunar surface less than 1 km in 
     diameter using a subset of the Spectral Profiler data published 
     in LUCEYETAL2014B.  As lighting conditions continuously changed 
     during the course of the mission, the data were confined to beta 
     angles (the angle between the plane of the spacecraft orbit and 
     the Moon-Sun vector) less than 45 degrees, and latitudes within 
     50 degrees of the equator to capture optimum lighting.  These 
     conditions were met several times during the course of the 
     mission; the data used here are those obtained during revolutions 
     (orbits) in the range 4124 and 4999.  The data were 
     photometrically corrected using the constants of YOKOTAETAL2011 
     with the 'high albedo' parameters.
     
     The archive contains 8183 records (separate spectra) of a total of
     3622 unique craters (some larger craters or those with more
     extensive ejecta were sampled by more than one spectrum).  The
     record also contains: the latitude and longitude of the spectrum 
     as reported in the JAXA archive; the revolution number; a flag
     indicating the crater is represented by a single spectrum (value =
     0) or by several sequential spectra (value=1); the FeO content of
     the location as using the algorithm of LAWRENCEETAL2002; the OMAT 
     value of the location using the algorithm of LUCEYETAL2000; a six 
     element vector that contains the estimated mineralogical
     composition of the site as presented in LUCEYETAL2014B; and the
     spectrum consisting of 153 spectral channels.  The wavelengths 
     are a subset of those provided in the JAXA archive culled of 
     overlapping channels.  Data beyond 1.7 microns are not usable 
     because of calibration issues that have been subsequently 
     overcome.
     
    Processing
    ==========
     Data for small craters were isolated in a two-step process.  First
     the OMAT parameter of LUCEYETAL2000 was calculated to produce
     candidate immature spectra by imposing a cutoff of 0.3 or greater.
     Each candidate was then visually inspected using Multiband Imager
     data and classified as a crater less than 1 km in diameter or
     'other.'  Only data classified as small craters are contained in
     this archive.

    The data contained in this archive were obtained from the SELENE 
    Data Archive, a website maintained by the Japanese Space Agency 
    JAXA.  The individual records have been photometrically corrected 
    and redundant spectral channels have been removed.  Spectral 
    reflectance data at wavelengths beyond 1.7 microns are not valid 
    in this archive.  A corrected version of data at these wavelengths 
    was not available at the time of processing these data.  Data 
    values of -99 indicate invalid data entries.
