[SAC-HELP] sonogram and spectrogram problem_2nd email

[Brian Savage]

Along the lines that George suggested.  Upgrading to a newer version  
of sac should solve your issue.  The problem you are experiencing was  
fixed in SAC version 100.1 in 2005 ( 101.0 in 2007 ).  Using either  
SAC distributed by IRIS or MacSac should solve your problems.
