The program assumes that all frequencies are in radians/sec, unless a HRTZ data record has been used to change this to Hertz (cycles/sec).
Note: The standard deviation, sigma (
), is always in radians/sec.

(1)-(2) Start/Finish Frequency - The lowest/highest frequency at which the spectrum is defined. Aqwa assumes that there is no wave frequency energy outside this range. If these fields are left blank, defaults will be calculated as follows:
First, the peak frequency (5) is converted to rad/s. Then:
Start frequency: 
, subject to a max of 100 rad/s and min of
0.001 rad/s.
Finish frequency: 
, subject to a max of 100 rad/s and min of
0.001 rad/s.
If 
then 
rad/s and 
rad/s.
(3) Standard deviation, 
. The minimum allowed value of
