Table 5:

Estimation of typical limiting magnitude as a function of the different spectral resolution modes.
Resolution	R	Typical lim. magnitude	Best perf.
Low	1700	6.8	7.5
Medium	6000	6.5	7.5
High	30 000	4.2	5.5

These values are presented for the median value of r₀ at Mount Wilson i.e. 8 cm. We also indicate the best performances assuming an r₀ of 15 cm.
