WINQUAKE FILTERING, SCALING, and DOWNSAMPLING
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.
