I have made some small changes in AmaSeis and in the Stations program.
2008.02.02: At request of John Lahr, Normalized the Fourier Transform so that when analyzing noise, the amplitude remains relatively constant as you extract different length signsls. Stations program in AmaSeisAux now automatically downloads the IRISEdStations.xml file from the IRIS download site.
The Stations program displays a map of the world showing the stations that are providing real-time upload of their data. You just click on one of these stations and the last day's data are downloaded and displayed on an AmaSeis screen. Consider adding your station to those who are automatically uploading their data.
To obtain these programs, follow this link:
http://bingweb.binghamton.edu/~ajones/AmaSeis.html
Note, that this link has changed. The older www.geol.binghamton.edu computer is being phased out. Please change your links.

Jerry,
Thanks for the heads up. I switched to multi-threaded libraries recently and forgot to include them in the distribution. This has been fixed. Try downloading again.
I'm sorry for the problem.

Hi Dr. Jones,
I have downloaded, removed, and reinstalled the latest version of AmaSeis three times and can never get it to load. Every time I try to start the program I get the following error message "as1.exe unable to locate component. OWL52t.dll was not found". I searched the internet for this file with no success. Any suggestions?

Tom,
The analog-to-digital converter (the black box) has a zero-setting knob which is very sensitive. Also, I believe that the electronic components alter their characteristics change. It has nothing to do with the boom not being centered because the device reads velocity, not position. It can be way off center but still have the trace right on line. There are two ways to recenter the line: (1) with the knob or (2) with the zero adjustment in AmaSeis.

I had a query from a teacher who is using the Amaseis software. I
noticed in a helicorder screen dump that he sent me, that the seismic
trace was not co-incident with the helicorder hour line, so I asked him
to adjust the zero value until there both were co-incident, but then he
replied with this question,
What is the origin of the zero value, is it due to the boom not being
perfectly centred and causing an offset in the voltage output of the
coil?? Just wondering?
Would anyone suggest an answer, please
Sincerely
Tom Blake

The amplifier in the little black box is the cause of the DC
offset. It has nothing to do with the boom position, as the output
of the coil and magnet is zero whenever there is no motion between
the coil and magnet, regardless of the boom position.
