Abstract: This code compute the average halo sparsity of massive halos (>1013 MSun h-1) at a given redshift for a given cosmological model by solving Eq. (4) in Corasaniti et al. (2018) for two different overdensity cases (<s200,500> and <s500,1000>). Two different mass function parametrisations are implemented: the Sheth-Tormen calibrated mass function formula by Despali et al. 2016 and that calibrated using the RayGalGroupSims simulation discussed in Corasaniti et al. (2018). The input linear matter power spectrum for a given set of cosm...
