What this work contributes
Raman map values average across the illumination spot. Raman 2D linewidth can nevertheless indicate strain variation below that spot size.
Where the evidence stops
Sub-spot sensitivity does not produce a spatial image of each nanoscale boundary. A blur slider is an illustrative point-spread model, not a reconstruction of these experiments or the cuprate sample.
