Questions about the summary

emiliaxin opened this issue · comments

Dear @hvasbath
I got the "summary.txt" for my case. And I would like to know why dip>90° in the result?
Also, does "hpd_0.5, hpd_99.5" mean to get 99% confidence interval for each parameter?

Here are my summary.txt.
summary.txt

Could you please give me some suggestions?
Thank you very much!

yes the hpds are like quantiles from 0.5 to 99.5 percent.
Dip above 90 means dip towards the other direction. E.g. if strike is 0 dip of 98 means 82 degree dip towards West.
I wonder why you did not ask that earlier when you specified the dip prior to be above 90 degree ;) ?

Thank you very much for your patient response.
I set Dip between 0 and 90 degrees at the beginning, but got bad results as shown in the figure below.

Yes! Perfect, so thats also why this functionality exists ;) . Sometimes its not so clear whether a faults dips one or the other side and in the setup one needs that possibility to sample both sides. Of course, a strike of 289 and a dip of 82 would be able to resolve the same fault configuration, but due to the large jump in strikes its harder to sample. Which is why I went for that other possibility with dips above 90degree.

Thank you!
