They are mosaics that are produced by ingesting the Level 2 Stokes 1 parameter into the ISIS software. The mosaics are produced for the entire lunar globe (i.e., regions between -180 and 180 longitude and -90 to 90 latitude). Unlike the lower-level products, these are composed of data sets collected during multiple acquisitions and are produced manually using the ISIS software provided by the Astrogeology branch of the USGS." ============================================================================= PARAMETER DESCRIPTIONS ============================================================================= S1 = "First Stokes parameter product, defined as S1 = |ERH| + |ERV|." S2 = "Second Stokes parameter product, defined as S2 = |ERH| - |ERV|." S3 = "Third Stokes parameter product, defined as S3 = 2*Re." S4 = "Fourth Stokes parameter product, defined as S4 = -2*Im." OC = "Opposite sense parameter product, defined as OC = S1 + S4." SC = "Same sense parameter product, defined as SC = S1 - S4." CPR = "Circular Polarization Ratio product defined as the ratio of the same sense circular polarization to the opposite sense circular polarization (CPR = SC / OS)." LPR = "Linear polarization ratio parameter product, defined as LPR = (S1 - S2)/(S1 + S2)." M = "Degree of Polarization daughter product, defined as M = [(S2^2 + S3^2 + S4^2)^0.5]/S1." MC = "Degree of Circular Polarization, defined as MC = -S4/M*S1." ML = "Degree of linear polarization parameter product, defined as ML = [(S2^2 + S3^2)^0.5]/[M*S1]."
