Hi Fabiola, I noticed in the log files that you selected time windows between 30 and 3600 s. This option is there a bit for historical reasons. I suggest you do not use it. Prefer "Exactly". This option was there at a time when FFT was not achieved with FFTW and restricted to power of 2 nu...

Hi Chenuy, Hobiger et al. 2013 also tried successfully to invert both flanks. Your profiles nicely reproduce the observed ellipticity curve even if it is not perfect. Just one detail, the errors look rather large. I'd like to make sure that there was no error while importing this curve into dinver a...

Hi,

What kind of theoretical HVSR? Through the assumption of energy equipartition (Sanchez-Sesma et al. 2011 and many other papers after them, e.g. Garcia-Jerez et al. 2016)? No, I've never coded it inside geospy.

Cosine taper is continuous modification of the amplitude of the signal over the whole window. Usually, only the ends of the signal window should be modified. The best choice is then 'Tukey', a flat central part at 1 and cosine variations to 0 on both ends. The parameter is length (%) of the affected...

Hi, As a first approach, you can manually pick the two portions of dispersion curves on spac2disp plot ([~2,~3] Hz and [~7,~12] Hz). Export the curves to a file and import them into dinver specifying the modes appropriately. Did you try Capon FK? Are there also two modes? Are they three-component ge...

Can you post the log files generated by each version? Standard deviations and individual curves look quite different between the two versions. Were they calculated with the same parameters? There might be minor differences even though the parameters are at the same values because computation evolved...

Hi Fabiola, Here are some answers. It they are incomplete feel free to continue the discussion. You have to select "Tukey". You have to set the signal property "AmplitudeUnit" (see menu "View/Set data fields" for a table to show/edit it) to Acceleration . Set also "...

From November 2024, the question asked for new registrations is changed to a code that must be requested by sending an email to Marc Wathelet (his email address can be found in scientific papers when he is the corresponding author). In your message, add a justification for your registration. It help...

Did you try to start the application through a terminal? It might output useful information.

min and max velocities are used to define the grid search (translated into max and min wavenumbers). N maxima are effectively picked using the grid search. Upon saving the results, the min and max velocity are again checked. I'm unsure whether this second check is really useful. Close to the wavenum...

Hi Leandro,

It looks like that the width of the cosine filter is too small. The damping effect always disappears if the width tends to 0 because the signal reduces to a sine or a cosine function. Try to enlarge a bit the bandwidth and check if the damping is increased.

If the number are coming from max2curve , you have to change the column headers. Values are not in degrees. You have to select 'Ellipticity (H/V)' for the mean values. For the error, I'm not so sure. It should be 'H/V stddev (approx)' or 'H/V*stddev (approx)'. Try both and compare with the plot of m...

Is it possible to obtain the value of F-K spectra (the beampower value in time window browser)?

No apparently there is no entry in the context menu to export the values. The code should be slightly modified

Now, all grid plots have an export value option in the context menu.

Now all grid plots have their 'Export values' menu (context menu).

With branch 3.6, the presence of these third party libraries are tested during the configuration. If not found, the code using these libraries is skipped during the compilation.
