Caution
The datas entered in the table are saved only if the related "save" button has been activated.
Before saving input datas, all the active cells have to be filled.

The aperture/obscuration parameters are positive or null.
D_max values can not exceed the value of the diameter D of the surface defined in the mandatory parameters table.
D_min < D_max.
The only limitation on X_max and Y_max is that they define surface boundaries which are achievable.
In any case : X_min < X_max and Y_min < Y_max.


For more details concerning the links and obturations table, see the related tutorial.
