Upper panel: Bound halo mass function as estimated using STRAWBERRY outputs on a single simulation using ten different values of the large scale parameter, $\stackrel{\sim }{\delta }$, ranging from 0 to 10.939. Lower panel: Relative difference with respect to halo mass function estimated using the nominal value ($\stackrel{\sim }{\delta }=4.55165$) used in this work. The shaded region corresponds a 5% deviation.
