Re: SPAC use

Hi Marc, Find below the tables from two sites (RIV.txt and (SYDH.txt) The RIV site could not be processed. The SYDH is the one where end time 6h 18m 59s couldn't be processed, while 6h 19m 59 s was processed. I use only vertical component. Why do you need the H/V toolbox? Unless you mean the SPAC to...

Re: SPAC use

Hi Marc, I check all you said. Time looks all right. Still cannot figure out what causes the problem. Just by chance, I tried to reprocessed some of the data (that worked before) cutting a bit of time, when I noticed that Geopsy refuses to process in some cases. Unfortunately it does not make sense ...

SPAC use

Hi Marc, I was wondering why in some cases I can process SPAC data while in others not. My data belong to the same data set, and till now out of 20 sites, about 12 result in *gpy database. I don't see why Geopsy refuses to process the rest of the sites. Data look reasonable, I cannot detect differen...

Re: spac2disp- colours and dispersion curve

Hi Marc, Thanks for the suggestion-paper. It was very helpful. Question: The auto-correlation curves must be inverted all together, or individually? In my case I noticed a misfit of ~0.8 if all rings are processed together and a value of 0.2 if individually. It is very difficult to drop the misfit w...

spac2disp- colours and dispersion curve

target.pdf Dear Marc, I just cannot find info about the meaning of colours in the slowness/freq curve on the low-left side, when presenting results of spac2disp. There is yellow, green, blue etc and there seem to be more pronounced when the number of cells is reduced. Why? Also, in the documentatio...

Re: Dispersion curves

Dear Marc, After checking the December updates of the manual, and comparing to test data, I came to the conclusion that my problem could be related to poor data quality. I tried a pair of stations from active experiments where continuously working vibrator (with different frequencies) was recorded. ...

Re: max2curve

sorry for late reply. It is output of conventional F-K toolbox that I can not visualize with max2curve. Surprisingly, results of F-K for passive experiments can be visualized.

Re: Dispersion curves

Dear Marc,

I don't load any curves from ascii files. The job is done automatically on the waveforms (what I load). Waveforms are in sac format and when imported in geopsy, they look ok. I only do 'set receivers' for the distances. This is why I don't really understand what goes wrong.

Dispersion curves

Dear Marc, When I process my data with both passive and active methods (f-k tools), I obtain dispersion curves which are somehow the other way around of what it should be. Lower frequency waves are slower than those at higher frequencies, meanwhile following the theory it should be vice-versa. I'm a...

max2curve

Hi,

I wanted to use max2curve from the f-k conventional too in geopsy, but when I tried to load the already existing *.max file it says "no max result can be loaded". Any idea what may cause that?
thanks, Theodora

Re: Dinver dispersion and ground profile plots

Hi,
I download the geopsy.org package, release2.4.2, src, from download page. Is that the stable or the development release? And if it is development, where can I find the stable src?
thanks,

Dinver dispersion and ground profile plots

Dear Marc, I am new user of dinver and started with the theoretical exercise supplied in the manual. Although forward modelling gave results as expected following inversion procedures significantly differ from those in the manual. First, run inversion menu is not the same as in the manual. Second, u...
