degrees of freedom

[lucas corach]

Hello Michael and everyone in the group!

Is there a way to set the number of degrees of freedom (or its inverse) when declaring a complex uncertain number?

 I can´t find how to do it and the consequence is that when obtaining a coverage interval for a complex quantity unclib considers that has infinite degrees of freedom,

 so the rectangle is obtained using a normal distribution to get the coverage factor 

(well, that is what I believe after being able to reproduce the results using the normal distribution instead of a t-student distribution which is what GUM recommends). 

Thank you

Lucas
