Notes. In the three sections of the table, we fix the fiducial values of p to the values we find in Table 3 for the halos with masses similar to those that host ELGs, LRGs and QSOs in Yuan et al. (2024) (bin 4, bin 8, and bin 6) respectively. We also consider three fiducial fNL values, as listed in each of the three rows. In the first for each tracer, we assume p = 1 and we fix bϕ using Eq. (13). In the second column, labeled as pfid, we conduct the fitting in the same way, but we fix p to the fiducial value for each sample. Finally, in the prior columns, we use our results for p to conduct the fits with p = 0.895 ± 0.055, p = 1.11 ± 0.27, and p = 0.973 ± 0.077 for the ELG, LRG, and QSO-like samples, respectively.
