Helpful Hints

■ The most commonly used formulas are indicated by an asterisk.

■ The values for “X,” “Y” and “Z” are taken in descending order. For example,

the value for “X” is greater than the value for “Y”

■ The values are for successive singular harmonic images. Do not use

multiple images.

■ If two points are recorded, equation (1 Y gives only approximate results.

Equations (2) with (4) and (3) with (5) are more precise, but error can be

introduced due to the rounding.

■ If three points are found, Equation (6) is the most commonly-used formula.

■ For completeness, equations (9) through (21) offer mathematical derivations

and condensed versions of Equation (6). Also included are the formulas for

calculating S
