Graphics QUEST3D Procedure

Select the required item in the NUMERIC sub-menu and respond to the standard numeric prompts.

Basic QUEST Procedure

Ex.

T1  *ALPHA  89.9  90.1 

This will register hits for entries having the author's unit cell alpha dimension in the range 89.9deg. - 90.1deg..

Remarks

These items are variance as floating point numbers, and so QUEST requires a decimal point in values used in these tests.

To cater for experimental variance, such searches should always be expressed in terms of ranges of values.
