In a multipole expansion in electrostatics, how do we select the origin? For instance, if there is a linear continuous distribution of charge $+Q$ (say from $x = -a$ to $x = +a$). Is there any rule such as: midpoint ($z$ = Zero in this case). For opposite charges does it have to be the centre of the charge distribution where effective charge = zero?
