Hi Marc,
manually applying a standard deviation of 10% to a dispersion curve I get a bar that seems absolutely incorrect to me. What could be the problem? I recently installed windows 11....is that going to be it? Is there a way to fix it (even increasing the number of decimals nothing happens)?
Thank you
Luigi

Re: anomalous Standard Deviation
Hi Luigi,
Try to set it manually to 1.1. Is it better?
Best regards,
Marc

Re: anomalous Standard Deviation
Hi Marc,
with 1.1 is fine. Till present I had always successfully used 0.1.
Is there a reason for this?
Thanks

Re: anomalous Standard Deviation
Was it with 3.4.2? With older releases the uncertainty where not processed the same way and it is possible that 0.1 was fine.
Re: anomalous Standard Deviation
Of course,3.4.2, that's why I was surprised both that 0.1, which always worked, was no longer correct, and that 1.1 gave the right result, overnight.
With Geopsy 2.10 to get 10% I have to write 0.001.

Re: anomalous Standard Deviation
I don't why either. If you manage to make it work with 0.1 again, try to identify the context and conditions. If I can also reproduce it, it will be easier to fix.
Re: anomalous Standard Deviation
I have tested previous dispersion curves that correctly represented 10% with 0.1 and found that they all now have the anomaly of representing 10% with 1.1.
Previously I had recorded that the mean curve automatically provided absurd standard deviation bars, equal to the ones I now obtain by applying an SD of 0.1 (the two curves to be averaged have no SD, see attached jpg).
If I apply an SD of 10% with 1.1 to the two curves, I obtain an average curve with an SD that is >30%. Is it wrong or am I wrong (see the jpg STD_average_1)?
