Sketch of data analysis carried out in 6 steps. (1) Build the atomistic model of each phase; (2) compute the scattering profile of all the nanocrystals of each phase $I_p\left(Q_i,d_{p,j}\right)$ by using the DEBUSSY suite; (3) build the inversion matrix $A_{i,k}$; (4) concatenate all the unknowns $N_p\left(d_{p,j}\right)$ into a single array $N_k$; (5) run the iterative inversion procedure and correct $N_k^r$ by comparing the measured data $I^m\left(Q_i\right)$ with the reconstructed ones $I^r\left(Q_i\right)$. At convergence, the final solution is $N_k^{r_{\ast }}$; (6) recover the final number and mass diameter distributions by parsing the solution $N_k^{r_{\ast }}$. Mass distributions are computed from number distributions as $M_p\left(d_{p,j}\right)=N_p\left(d_{p,j}\right)m_{p,j}.$
