Run of growing ice crystals with cooler set at -45C and pressure set at 100Pa.
Interest was at determining whether the spacing between TPS was a funciton of pressure differences.
These images were taken in the growth phase of the crystal, looking at the prismatic facet near an edge.
Image 6-17-11 -39.2C notext shows an interesting edge-edge area in the upper right hand corner. A similar 
structure is seen on most of the other images.
