Caption:
(a) Example of an image captured by the infrared camera after the sample temperature has reached a stable state with the approximate position and size of the measurement spot of $143\times 72$ pixels, corresponding to approx. $1.9\times 0.9$\,mm. (b) Temperature evolution inside the measurement spot marked by the rectangle in (a). The shaded area gives the 95\% range of temperatures at each captured image measured at 7 fps.

Notes:
None

Plot data:
plot_0: Lower limit percentile interval
plot_1: Upper limit percentile interval
plot_2: Spatial mean temperature $\overline{T}$
plot_3: Temporal mean temperature $\overline{T}\approx62.5\,^\circ$C
