SUMMARY

Removes the seismic Q factor from spectral data.

SYNTAX

RQ [Q v],[R v],[C v]

INPUT

Q v: Set quality factor to v.

R v: Set distance in km. to v.

C v: Set group velocity in km/sec to v

Q v:	Set quality factor to v.
R v:	Set distance in km. to v.
C v:	Set group velocity in km/sec to v

DEFAULT VALUES

RQ Q 1. R 0. C 1.

DESCRIPTION

The equation used to correct the amplitude is given below:
AMP_corrected(F) = AMP_uncorrected(F) * Exp( (pi*R*F) / (Q*C) )
where: F is the frequency in Hz. R is the distance in km. C is the group velocity in km/sec. Q is the the nondimensional quality factor.

ERROR MESSAGES

1301: No data files read in.
1305: Illegal operation on time series file

WARNING MESSAGES

1604: Following file now in amplitude-phase format:
- file was in real-imaginary format.

LIMITATIONS

Can only handle constants for the various parameters. Modifications to allow these parameters to vary with frequency may be added at a later date.
