Temperature dependence of the amplitudes of the irreps conforming the $P b n m$ and $R \overline{3} c$ structure of $\mathrm{SrPrFeRuO}_{6}$, and $\Psi$ and $\Phi$ tilt angles, as obtained from the NPD data refinement. The amplitudes of the irreps in the high symmetry phase have been scaled (multiplied by $3 / 2$) to see the evolution, since the program AMPLIMODES uses mode normalization within the corresponding primitive unit cell.
