Basic QUEST Procedure

Ex.

T1  *CELA  10.0  15.0
This will register hits for entries having the author's unit cell a dimension in the range 10 - 15 Å.

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.
