Probing the effect of varying the source shift in the outward direction, $\mu_{\mathrm{out}}$, within the THERMINATOR 2 framework. To achieve this, particle pairs are formed from the simulation, but with altered spatial characteristics achieved by drawing the out, side, and long components from predetermined Gaussian distributions. The sources in all three directions are Gaussians of width 5 fm The distributions used for the side and long direction are centered at the origin, while the shift in the outward direction, $\mu_{\mathrm{out}}$, is varied The plots show fits resulting from sources with $\mu_{\mathrm{out}}$ increasing from 0 to 6 fm. The effect of increasing $\mu_{\mathrm{out}}$ clearly increases the effective radius extracted in the fit
