Misfit calculation

Hi Marc, I have few questions about how to calculate the misfit for dipsersion curve inversion in DINVER. When only phase velocity is considered for inversion, does the misfit follows the equation 3.38 in your PhD thesis? If so, does the 'uncertainty' mean arithmetic or geometric standard deviation?...

Re: Few questions for FK analysis

Hi Marc, I am running Geopsy (3.5.2) under windows 10 (22H2). There are two velocities (two rows) for the two peaks on FK spectrum in the max file. After few more testing, I believe the reason that there was only one peak on the FK spectrum in FK_max2peaks_relative0%.png is because the vmax in FK gr...

Re: Few questions for FK analysis

Dear Marc, Thank you for your prompt reply. For the attached dispersion curve figure, the probability density is not computed at 1.24 Hz as you said. Sorry for the confusion. I have checked the FK spectra, and the reason of the gap around 1.24 Hz is just as you said, the maximum peaks of FK spectra ...

Few questions for FK analysis

Hi Marc, I have few questions for the parameters and output data while performing FK analysis: 1. Is it possible to obtain the value of F-K spectra (the beampower value in time window browser)? 2. What is the 'valid' inside the output max file stands for? 3. What does the 'weight' mean in gphistogra...

Create Dinver parameters through command lines

Hi Marc,

I am using dinver to perform dispersion curve inversion.
Is it possible to create parameters (*.param) for input through command line?

Questions about geopsy-hv usage

Hi Marc, I'm trying to use the geopsy-hv to estimate H/V hourly, I have some problems when I use the -load-windows option. The terminal shows: The ASCII format without header imply that you fill in the correct information yourself in a table. Choose menu "view/new table" and change the Sam...

Can Dinver estimate resolving kernel

Hi Marc,

I'm using Dinver for my dispersion curve inversion.
In order to examine the resolvable depth,
I'm wondering whether Dinver can estimate the resolving kernel?

Best regards,
Uki
