Caption:
Example image taken from an experimental run of \FetOf particles at a volume flow of $\mathrm{d}V/\mathrm{d}t=0.135$\,mL/min with mean temperature $\overline{T}=78.3^\circ$C, at reaction begin. Red contour lines highlight the particle mask; each is assigned an ID. The detected particle perimeter is redrawn in blue, and the calculated projected area-equivalent diameter $d = \sqrt{4/\pi A}$ is indicated next to the particle. The corresponding raw image is shown in Fig. A.3 in the Appendix.

Notes:
None
