You could check "Scan Type" setting under Field Curvature/Distortion curve to either scan across x or y direction. In addition, you could use Grid Distortion, which give you an overview of distortion. PV/SzfvIq

For coma, it normally displays as a parabolic curve in Ray Fan plot but it can be a bit complicated to analyse if you also have other dominating aberrations. Another way to look into coma is by looking at Zernike Standard Coefficeint, the term 5 and 6 correspond to coma in y and x orientation respectively. ZERN operands should help to extract these values. G9P)Y#WB

However, these are only for the third order. Once you go higher order aberrations, the conversion between Seidel and Zernike becomes not so stright forward.

可以利用TRAX TRAY REAX REAY這幾個(gè)操作數(shù)根據(jù)像差的定義來(lái)描述像差（包括高階的像差），與transverse ray fan plot類(lèi)似。

感謝各位的指點(diǎn)

try to use "chief ray angle = 0" solve in "radius" column and limit the distance (mxca operand) in merit function
