Table 3.

Model parameters, split into cosmological and nuisance ones, with the latter further divided into the two bias models described in Sect. 3.

	Parameter	Prior
Cosmology
	h	𝒰 [0.55, 0.85]
	ω_c	𝒰 [0.08, 0.16]
Eulerian bias expansion
Bias	b₁	𝒰 [0.25, 4]
	b₂	𝒰 [−10, 10]
	$b_{G_{2}}$ $b_{{\cal G}_2}$	𝒰 [−4, 4] or fixed to Eq. (37)
	b_Γ₃	𝒰 [−8, 8] or fixed to Eq. (36)
Counterterm	c₀ [(Mpc/h)²]	𝒰 [−100, 100]
Shot-noise	α_P, 1	𝒰 [−1, 2]
	α_P, 2 [(Mpc/h)²]	𝒰 [−5, 5] or fixed to 0
Hybrid Lagrangian bias expansion
Bias	$b_{1}^{L}$ $b_1^{\,{\cal L}}$	𝒰 [−1, 3]
	$b_{2}^{L}$ $b_2^{\,{\cal L}}$	𝒰 [−3, 3]
	$b_{s^{2}}^{L}$ $b_{s^2}^{\,{\cal L}}$	𝒰 [−10, 10]
	$b_{\nabla^{2} δ}^{L} [{(Mpc / h)}^{2}]$ $b_{\nabla^2 \delta}^{\,{\cal L}}\,\big[(\mathrm{Mpc}/h)^2\big]$	𝒰 [−10, 10]
Shot-noise	α_P, 1	𝒰 [−1, 1]

Notes. The nuisance parameters consist of bias parameters, EFTofLSS counterterm, and shot-noise terms. For each parameter, the imposed prior is specified in the last column of the table. The letter 𝒰 stands for a uniform distribution, with edges identified by the first and second element of the pair, respectively.
