This run was done varying the pressure of the SEM, with starting at 200Pa and incrementally working
down to 140Pa. As usual, the runs were done witht the cooler set at -45C looking for growth. 
140Pa formation shows evidence for growth across the prismatic facet by microfacets. The image facets out
also shows a generic screen of the crystals when grown at 140Pa, noticeably with more wavy lines
along the facets.
