Table 1:

Preliminary system specification to preserve the advantage of a MAPLC (n=2) over an APLC (n=1).

Segment reflectivity ($\%$ ptv) <1
Segment low-order aberrations1 (nm rms) <50
Offset pointing (mas rms) <0.3
Pupil shear ($\%$) <0.2

Notes. The advantage of MAPLC over APLC only concerns angular separations higher than the IWA. (1) Segment aberration levels correspond to XAO-uncorrected values.
