Analyses aimed at determining the darkest positions on the 3 MIPS arrays as a function of CSMM position are linked here. 2 sets of data were obtained for each array. The first dataset was taken on a coarse grid of CSMM positions, while the second was taken on a fine grid of CSMM positions. The second kind of data was not taken over a wide enough range of CSMM positions to convincingly demonstrate a minumum in stray light reaching the arrays, and so should probabl be repeated during CTA testing.
