figue reading dates for an x y plot

Hi Marc, Came across creating xy plots with dates using figue but doesn't seem to point to the proper absolute time reference. In my file I have x in the format yyyyMMddhhmmssz (as per -h) and I use the starting time as input to the command -x-abs-time-ref. It is read and plotted in figue but absolu...

Time Frequency Analysis

Hi Marc,

Is there a workaround to the warning/error message saying there's a limit in memory consumption after running Time Frequency Analysis?
Please see attached image for reference.

Thanks,
Leandro

Forward modelling

Hi Marc, This may be a brush up of theoretical and practical understanding. If I have 2 clear peaks in the HVSR spectra and I want to forward model using gpsh or gpell, do I account for both peaks as 2 layers above half space in the text file? Or do I use 2 different text files with one layer above ...

Re: HVTFA - ellipticity inversions

Hi Marc, Would this be correct? Upon import, I changed the columns as you have suggested to 'Ellipticity (H/V)' for the mean values and 'H/V stddev (approx)' for the error. I also changed the curve value from 'Singed' to 'Absolute'. The ellipticity I got after inversion is this: Ell.png With ellipti...

Re: HVTFA - ellipticity inversions

Hi Marc, What should be the column designations when importing ellipticity I obtained from the old max2curve if I wanted to use the newer dinver version? I have tried the default but am getting larger misfits as compared to the older version. In the newer version I am getting as high as 10 whereas t...

Geopsy damping

Hi Marc, I have a dataset that we are quite unsure if the peak that we are seeing in the vertical component is of industrial origin. I have been testing this hypothesis using damping toolbox but I am not quite sure of which filter method to use - Butterworth vs Cosine taper. I have tried using a cos...

split signal per hour

Hi Marc,

Would you perhaps have a code that cuts and exports SAC signal per hour?

Thank you!

HVTFA - ellipticity inversions

Hi Marc, Posting here as per your advice. I hope this email finds you well. I have been a Geopsy user for quite some time now but only restricted to HVSR processing. I am now exploring how to invert fundamental mode rayleigh wave ellipticity since I am soon to work on glacial ice thickness estimates...
