  1. Melt volume reported in vol.% of the total lunar crust. FWHM = full width half max of melt production (My), defined herein as magmatic duration.
  2. Magmatic timing = time to 50% cumulative melt volume. Farthest neighbor = average distance between each Mg-suite detection with successful models indicated by left-half circle with “x”.
  3. Exposure Prop. = exposure proportion of Mg-suite identifications with successful models indicated by right-half circle with “x”.
  4. Spatial constraints of farthest neighbor and exposure proportion are evaluated within the range of Melt Detection Threshold given between 2 and 7%, with successful parameter combinations signified by an “x” inside a full circle.
