It is possible
to use different presentations for some
parameters. For instance, a slightly oval
shape of the girdle can be described by
two diameters, minimum and maximum. Alternatively,
it can be specified by maximum diameter
and deviation (brilliant cut) or ratio
of maximum and minimum diameters (fancy
cuts).
To choose a presentation
option of such a parameter, point the
mouse cursor to the parameter's name and
click right mouse button. A menu appears,
allowing to select a presentation option:
The picture above
was taken when the mouse cursor was over
"Girdle ratio" field and the
right mouse button was pressed. As you
see, a menu allows to select between showing
maximum and minimum diameters or just
one diameter and ratio of diameters.
There are other
dual parameters:
Girdle square deviation <-> Alternative
diameter (measured at direction 45°);
Star facet length <-> Table picture square-likeness.
There is also a
similar way to choose mass precision:
2 digits after decimal point <-> 4 digits.
