COBRA Repository for computing cosmological observables
Currently supports: (i) linear power spectrum in $\Lambda$CDM; (ii) linear power spectrum in extended parameter space including curvature, neutrinos,
By default, the code uses units of
All modules are vectorized, so you can feed L cosmologies at once by using L by D arrays, where D is the number of parameters per cosmology (D=6 for (i), D=10 for (ii), D=18 for (iii)). Due to memory constraints it is not advised to use L of more than a few hundred, after which the speedup saturates anyways. You can only pass one value of comp_max at a time, and only one grid of output k-values.
