Hi Marc, I understand that in order to plot the ellipticity curve using HVSR-derived 3-component data, Continuous Wavelet Transform (CWT) must be performed using the HV TFA tool found in the "Tools" menu. So, using the 3-component data I collected (in SAC file format), I extracted a .max f...

Hi Marc I am leaving a question because I would like to know more precisely about the guidelines established in SESAME. 1st Question: What does f_peak mentioned in item 4 of the Criteria for a clear H/V peak in the SESAME Guide Line mean? Does it represent the peak of each window? 2nd Question: Also...

Hi Marc, Thank you for your excellent response. However, I still have some unresolved questions, so I would like to ask further: 1. You mentioned that the 1st and 2nd criteria of a clear peak can be verified, but there is no indication for f0/4, 4f0 or A0/2. How can these values be identified? 2. Is...

Hi, Marc, Thank you for your response. It seems that many of my questions have been resolved. However, I think some of my previous questions might not have been clear enough, so I’d like to ask for clarification once again. [Regarding Question 1] When I saved the data via the mentioned path, I got a...

Hi Marc, I am currently using Geopsy for HVSR analysis and have several questions regarding its use. 1. I wanted to assess whether the analyzed data meets the SESAME criteria (e.g., whether the frequency with an A/2 value falls within a specific range) and tried to download the graph. To do this, I ...

Hi Marc, I was trying to use the HVSR function in the Geopsy program. When I looked at the contents of the Processing tab in the Quick Start Tutorial, I noticed that there are various window functions in the Taper tab. However, except for certain functions (Blackman, Gaussian, Tukey), there are no a...
