Code for Bayesian Analysis
Some highlights:
package_install
settings to specify if they should be installed from pip, github or URL when cobaya-install
is run.planck_2018_lowl.EE
and planck_2018_low.TT
with native versions, and using GitHub-hosted clik
.A not-so-minor release containing the following user-facing changes, among others:
Updated BOSS DR16 (thanks Pablo Lemos!), BICEP-Keck 2021 (thanks Dominic Beck!) PolyChord v1.20.1 (thanks Will Handley!), CLASS v3.2 (thanks Julien Lesgourgues and Nils Schöneberg!), CAMB (always last master commit) and (un-)official SPT likelihoods (external, thanks Xavier Garrido!). Run cobaya-install cosmo --upgrade
to download them!
Added a convenient --minimize
flag to cobaya-run: just re-run your previous MCMC/PolyChord runs with this flag to start a minimization process starting from the best point of your previous sample.
File locking was introduced in a previous version as a way to prevent parallel runs (e.g. due non-working MPI installs) to overwrite each other, but it may cause problems in some systems. To disable it you can now set the environment variable COBAYA_USE_FILE_LOCKING=false
.
CAMB and CLASS: added Omega_b|cdm|nu_massive(z)
and angular_diameter_distance_2
. Pk_interpolator
can now extrapolate towards low k using extrap_kmin
.
CAMB and CLASS: added ignore_obsolete
option to be able to run with your modified older CAMB and CLASS versions.
CAMB: Support setting individual Accuracy parameters, e.g. Accuracy.AccurateBB
.
CLASS: added sigmaR(z)
, sigma8(z)
, fsgima8(z)
and Weyl potential power spectrum (were already in CAMB). Added direct access to some CLASS computation products, via new requisites CLASS_[background|thermodynamics|primordial|perturbations|sources]
. Changed default non_linear
to hmcode
(was none
).
Many small fixes to code and docs, thanks to Caterina Umilta, Paolo Campeti, Lukas Hergt, Will Handley, @valadur19, Adam Ormondroyd, Chris Walter, Jack Runburg and Paul Shah!
Don't forget to run cobaya-install cosmo --upgrade
after upgrading to Cobaya 3.2 to get the latest versions of all codes and likelihoods!
