  • S1600434 shows a small residual on the face, the edge, probably from first contact, and a back spot, probably a residual of the contamination
  • S1600435 shows a large halo on the face, like what you get when solvents dry on the surface leaving some traces
  • S1600436 has some red residual on the edge, likely first contact
