This is a test of comment nesting: a response to Comment #1. “It looks like the Fourier representation of is of the form

for some absolute constant C, where the integral is over the plane . Note that if one dropped the signum factor (and the constant C), this would be the formula for the Fourier transform for the pointwise product fgh, so perhaps it is good to think of as a variant of the product fgh.”
