What’s New in Halotools v0.6?¶
Halotools v0.6
is now available for installation with conda and pip. New features are summarized below. See Full Changelog for details on smaller issues and bug-fixes. See Version v0.x release history for full release history information.
Quick Installation Verification¶
It is now much faster to verify successful installation of the latest version of halotools. After installing the code, you can now run a targeted subset of unit tests, rather than the entire test suite:
import halotools
halotools.test_installation()
New Mock Observables¶
Radial distances and velocities¶
There are new functions in the mock_observables
sub-package that calculate element-wise radial distances and velocities, radial_distance
and radial_distance_and_velocity
.
Jackknife error estimation¶
New functions wp_jackknife
and rp_pi_tpcf_jackknife
give jackknife error estimation for the wp
and rp_pi_tpcf
functions.
Weighted pair counts as a function of (s, mu)¶
New halotools.mock_observables.pair_counters.weighted_npairs_s_mu
function gives weighting option for counting pairs in (s, mu) space.
Utility functions¶
Matching two distributions for statistical comparison¶
The halotools.utils.distribution_matching_indices
function Monte Carlo resamples one distribution until it matches another.
API Change¶
The
npairs_s_mu
function now has a change to the meaning of themu_bins
input argument. This argument should now be interpreted as the conventional mu=cos(theta_LOS) instead of mu=sin(theta_LOS).
