Remark: A zero on an angular slice is not joint smoothness
The diffracted coefficient and its nonvanishing criterion · lines 1157–1163
At a special fixed value of , a restricted scalar coefficient can vanish. That is not a neighbourhood on . The lower bound above is a joint statement in the angular and remaining variables. No inference from a single angular slice is used.
