I have a question concerning the alignment of the comma in the exercise below. We know that the comma moves to the top line, but where should the comma be placed vertically when the top line is shorter? Does it go at the end of the top line of the equation as shown in example (a) or is it placed outside of the equation using transcriber grouping signs as shown in example (b)? Technically the comma is not part of the equation.

We realize that if a Nemeth Code terminator were to be used in a similar situation the comma would go after the terminator aligned vertically outside of the equation.
