The Fisher gAlaxy suRvey cOde (FARO)

The Fisher gAlaxy suRvey cOde ($\texttt{FARO}$) is a new public Python code that computes the matrix for galaxy surveys observables. observables considered are linear multitracer 3D power spectrum, convergence spectrum weak lensing, and correlation between distribution convergence. allows tomographic model-independent analysis in which, scale-independent growth, following functions of redshift $A_a (z) \equiv \sigma_{8}(z) \, b_a (z)$, $R(z) f(z)$, $L(z) \Omega_{m} \Sigma (z)$ $E(z) H(z)/H_0$, together with function scale $\hat{P}(k)$, taken as free parameters each bins respectively. In addition, module change variables provided to project on any particular set required. built be fast possible user-friendly. As an application example, we forecast sensitivity future like DESI, Euclid, J-PAS LSST compare their performance different ranges.
