VIS
Resolving power TLR for VIS arm is lam/dlam = 7500 at 1.0 arcsec slit width. Observed values for 1.0'' are not available. Ploynomial fit (see Box 2) shows 7880 at 1.0 arcsec. Scaling the best-fit polynomial, by 7500/7880 (=0.952) results in the TLR for any slit (dashed line).

NIR
resolving power top level requirement for NIR arm is 4800 at 1.0 arcsec slit width. Ploynomial fit (see Box 2) shows 5120 at 1.0 arcsec. Scaling the best-fit polynomial, by 4800/5120 (=0.938) results in the TLR for any slit (dashed line).
