FK Tutorial, RTBF and Love dispersion

Hi Marc, prompted by your clarifications in response to my question (https://www.geopsy.org/forum/viewtopic.php?t=553) I revisited the FK Tutorial where the outputs of the lep_ring01_3C.gpy processing with RTBF are reported. In addition to the scripts for Rayleigh, ellipticity and noise outputs, the...

Re: Current status of SPAC functionality

Hi Marc, sorry for the delay, but I did not notice your reply. I don't know if I understand your request (I see the page file complete with all the plots) and therefore I am attaching the jpg where all the plots are included. I don't understand how this can happen. Maybe the jpg files cannot be save...

Re: Gphistogram and RTBF

Hi Marc, I am a little confused by your reply. If I understood correctly, from the RTBF process, only a Rayleigh dispersion can be obtained and a Love dispersion can only be the output of a Capon transverse process (always if Love waves are present). This is in stark contrast to the documentation ht...

Gphistogram and RTBF

Hi Marc, why can't gphistogram represent the PDF of the Transverse of a target file obtained with FK RTBF, while gpviewmax can do it? Comparing with gpviewmax some target files I noticed that the transverse vel / freq plots show a dispersive trend very similar to that of the vertical, but aliasing i...

Re: Current status of SPAC functionality

Hi, first of all thank you for giving me the opportunity to implement the little I know about the Spac 3C. So far I was stuck on the error message that appears when using spac2disp from the Geopsyland link. I tried to process with 3.4.2 a file of the tutorial database (lep_ring01_3C.gpy) with the po...

FK toolbox process type: Active process

Hi Marc, scrolling through the .max file of an FK process you will come across a comment zone where there is a list of the types of processes that are much more numerous than those that can be used by choosing from those listed in the FK toolbox. I suppose that these are processes that will be avail...

Re: semi rings on the co-array map

Hi Marc, Sorry if I expressed myself in an unclear way, but the question is much more practical: how to represent only the positive part in the plot of the co-arrays. Working on the Property editor I could not find a way to remove the negative part and in the end to get only semicircles instead of w...

Hi Marc,
how do you represent on the co-array map only the positive part of the rings?

Thank you

save HV peak

Hi Marc,
I found, wanting to save a f1 HV with the "save" function in peak editor, that an empty file is saved.
Is this a bug or is there another procedure to save the peaks f>0?
Thanks

more on Frequency rejection utility (FWA)

Hi Marc, I wrote to Brady Cox who very kindly and quickly replied to me. This is the gist of his words: As you may recall from my 2020 paper, n is the number of standard deviations. So, when using n = 2 we are incorporating approximately 95% of the f0 values ​​obtained from the various time windows....

Re: Frequency rejection

I wrote a few days ago (before to post here my question) to J.Ventassel, author of the hvsrpy code, but I haven't had an answer yet.

Frequency rejection

Hi Marc, I have a question about the tool frequency rejection (FWA). Opening the log file of an H / V curve calculated with this procedure I do not find the value of n (standard deviation) = 1.6 that I used. There is only a list of standard parameters preceded by the # symbol # Frequency domain wind...

Re: J Sesame and Geopsy

No, this is not the problem and I think the two attached images can better explain my question.
I ask if it is possible to save the data of the single windows (as it was possible to do with J Sesame) and represent them graphically (J-Sesame1).

Thanks
