In pyccl/halos/emulators/, I implemented halo based cosmological emulator called Dark Emulator (Nishimichi et al. 2019).
It calculates xihh/hm as an official set-up and has interfaces to calculate xigg/gm using HOD.
We utilized halo power spectrum Phh/hm to adjust several profiles in CCL packages.
pyccl/halos/emulators/darkemu1_pk.py is based on pyccl/halos/pk_2pt.py file and there are still possibilities to improve calculation speed.
