Parameters for spatial variations used for each case studied for each GSMT.

Thickness Variation

GSMT Case 1 Case 2 Case 3 Material
GMT n = –1 n = –2 n = –3 Al2O3
ELT 10% 20% 50% Si3N4
TMT 10% 20% 50% Si3N4

Notes. Peak-to-valley aberration applied is symmetric about zero and, as such, has positive and negative values. These randomly generated screens are then added to the nominal thicknesses described in Anche et al. (2023).
