WinQuake and SAC Utility Programs

WINQUAKE FILTERING, SCALING, and DOWNSAMPLING

This program will benefit all those who prepare WinQuake event files.

WQFILTER.exe (with WQFilterHlp.txt)

The features include:
(1) Logging of all operations done by WQFilter in the data operations field of the output WinQuake file
(2) Low pass and high pass filters that are better than the ones in WinQuake (in my opinion). 
(3) A special period-extending filter. See examples of the filter here.
(4) Ability to paste in a NEIC event report string from: http://earthquake.usgs.gov/eqcenter/recenteqsww/Quakes/quakes_all.php  (if you don't include "MAP" in the text, and you delete any tabs), or from:ftp://hazards.cr.usgs.gov/cnss/cnss_14.fing
(5) Ability to edit the Data Operations field of any WinQuake Type 4 file.
(6) Heliplot and detail display screens.
