RE: QUA22_D80
Hi Marianna,

my answer problably comes a bit late, sorry Sad ; QUA22_D80 has nothing to do with zenithal distance or elevation, it refers to the aberration coefficient of the quadrifoil (or quatrefoil) quasi-Zernike polynomial component with 22.5 deg orientation Z(-4;4). The D80 refers to the angular diameter of the disk that encloses 80% of the total spot light when only this specific component is considered.
