I don't have strong opinions on any of these, except that I think custom shift/scaling would likely be useful, and that if there's an established convention for normally distributed complex random numbers, we should likely stick to it. Send me what you think is best, I'll review it and merge it. If anyone on the list has input, please speak up. Andreas
