TSoft

A software package for the analysis of Time Series and Earth Tides

What's new on Tsoft?

2009-01-16: link to run Tsoft on Mac OS X (Intel); many thanks to Gilles Celli!

Version 2.1.2

2007-10-30

-Polar Motion: Accepts the new IERS / EOPC 2007 format.

!!!!!!!!!!!!!! To run the Polar motion tool you have to download the new EOPC files from ftp://hpiers.obspm.fr/iers/eop/eopc04_05 !!!!!!!!!!!!!!!!!!!

Version 2.0.14

2004-06-25:

- Browser when changing database; new scripts chgdatabase and apply steps; calculates polar motion using IERS coordinates

Previous releases

Coming (soon)

Compressed TSF file format (and possibility to save the files in the "GSE" file format)

Ocean Loading parameter set calculation (Meanwhile one can compute these parameters on H.-G. Scherneck’s free ocean loading provider (http://www.oso.chalmers.se/~loading/) – unfortunately not same format here : the Tsoft user must do it him[her]self).

Possibility to run the H.-G. Wenzel's ETERNA Earth tide analysis package directly from Tsoft (meanwhile you can download it from http://www.eas.slu.edu/GGP/ETERNA/ )

Worried about gaps and steps ?

TSOFT removes them all automatically !

While making your way to the highest tops don't be trapped by unexpected obstacles such as steps and gaps ...

Use TSOFT, the software that levels your path to success !

A brief description

TSoft is a software package for the analysis of time series and Earth Tide series, developed at the Royal Observatory of Belgium. In contrast to most of the existing systems, it allows the user to process the data in a fully interactive and graphical way, taking advantage of the extended graphics capabilities of the current computer systems. This approach has a number of important advantages, particularly in the field of error correction of (strongly perturbed) data, and the detection and processing of special events (e.g. free oscillations after Earthquakes). In addition, TSoft offers the possibility to write scripts, which allow one to simplify and speed up routine tasks considerably.

Tsoft can also be used as a nice and attractive educational tool, e.g. for signal processing (Calculation of spectra, aliasing, filtering, transfer function, ...)

The software offers the following tools:

Import and export of a variety of file formats
Convenient visualization and printing of data channels
Arithmetical calculations between different data channels
Changing sample rate & sample frame, using anti-aliasing filters
Calculation of synthetic tides and residuals, provide latitude dependent tidal parameter set
Automatic and interactive correction of spikes, earthquakes, steps, etc.
Time-dependent, nonlinear calibrations
Compensation of varying time shifts & calculation of time delay between channels (correlation)
A wide range of filters (FFT, LSQ, Butterworth, polynomial.)
Multilinear least squares fits using different drift models
Moving-window time dependent least square fits
Frequency-dependent admittance determination
Calculation of spectra and power spectra, using different data windowings
Moving-window time dependent spectra
Phase graphs
Calculation of transfer function (step response, sine waves)
Calculation of gravity gradient (multilinear least squares fits)

 

Computer requirements

The software runs on PC compatibles using Windows 95, Windows 98, Windows 2000 , Windows XP or Windows NT. It takes about 770kB on the hard disk, and is run preferably on a Pentium system with at least 16MB RAM memory. Graphical images can be printed out in black and white or in colour on any Windows printer. In addition, the software can export images to other Windows applications using the clipboard.

Availability

TSoft is a public domain software, which means that everyone is allowed to get a copy free of charge.

When citing Tsoft, please refer to:

Van Camp, M., and Vauterin, P., Tsoft: graphical and interactive software for the analysis of time series and Earth tides, Computers & Geosciences, 31(5) 631-640, 2005.

You can download a compressed version of the software, "tsoft_c.zip", which you should copy into the root of your file system and uncompress.

A "C:\Tsoft" directory should automatically be created with the 2 required sub-directories c:\Tsoft\macro (1 file) and c:\Tsoft\tidata (1 file) as well as 6 files in c:\Tsoft.

v2.1.2 : Download TSoft package (352k)

There is a manual available in MS-Word 97 format. You can download a self-extracting version of this manual (compressed with EasyZip).

Please have a look to this chapter before reporting bugs, and ensure that the encountered problems are really due to the new TSoft version.
