A small Radon-Nikod\'ym compact space from a parametrized diamond

Abstrak
A compact space $K$ is Radon-Nikod\'{y}m if there is a lower semi-continuous metric fragmenting $K$. In this note, we show that, under $\diamondsuit (\mathrm{non}{\mathcal{M}})$, there is a Radon-Nikod\'{y}m compact space of weight $\aleph_1$ with a continuous image that is not Radon-Nikod\'{y}m, which partially answers a question posed in arXiv:1112.4152 [math.FA].
