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

Hi Luigi,

Try to set it manually to 1.1. Is it better?
Best regards,

Marc

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

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.

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.

Regard

Luigi

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.

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)?
