Right, thanks. I have changed it to $\mu_A$ now.

(The “$\mu_S$” is a remnant of the origin of the construction of the entry in the discussion of BV-quantization of free fields, where the Gaussian factor is the exponentiation of the action functional “$S$”.)

]]>created *Gaussian probability distribution*, just for completeness
