Seismic Toolkit is a tool for processing and displaying seismic signal data in a graphical interface. It reads seismic signals in SAC format, and provides a variety of signal processing, such as filtering, spectral analysis, polarisation analysis, time-frequency representation, Hilbert transform, and singular value decomposition. Some utilities are included for useful seismological applications, like computation of Seismic Moment Mo, Mantle magnitude Mm and Moment magnitude Mw, MTPA spectral analysis, plotting focal mechanisms, computation (and plotting) of instrumental response from poles and zeros, and some usefull GMT (Generic Mapping Tool) scripts for plotting signals, responses, and time-frequency in Postscript files for high quality prints.

Changes:
The free_tab() function has been added in
dialog_sinle_chan.c to avoid a crash on
non-allocated memory of tab_file[]. A major bug
was corrected in the get_path() function for Win32
applications (the separator can be either "/" or
""). Free_mem() is called after closing the
ALL_Channels window (in the All_fct() function)
for recovering the allocated memory.
