Table 3.21. Angular despace spherical aberration at best focus (BF) and angular despace field coma for 2-mirror telescopes defined as in Table 3.2: |m2| = 4, |Ra| = 0.225, IN| = 10 and the despace is |ddi/f'| = 10-3, or ddi/f1 = -4• 10-3, ten times the decenter S of Table 3.20. The semi-field angle for the coma is upr1 = 15 arcmin
