v2026.04.0

This version includes several updates, most importantly revisited and optimised functions to compute the sample covariance from an ensemble of healpy Gaussian simulations. The full list of updates is the following:

• Restored and optimised sample covariance from healpy Gaussian simulations
• Updated phz reading function from euclidlib (the module was renamed)
• Added guard and updated environment.yaml for the incompatibility between heracles and scipy 1.17
• run_config now preserves the structure of the original config file
• Import input Cl files only if the associated probes are required
• Minor bugfixes

• Add the possibility to compute unbinned NaMaster Gaussian covariance
• Small bugfixes

Full Changelog: v2026.03.0...v2026.03.1

v2026.03.0

• Minor bugfixes

Full Changelog: v2026.02.2...v2026.03.0

v2026.02.2

Change the default Python version (in the environment.yaml file) to Python 3.13

Full Changelog: v2026.02.1...v2026.02.2

v2026.01.1

• Created DEMO.ipynb notebook to provide example input files, illustrate their formats, show how to run the code from a script, and how to load and manipulate the outputs.
• The config.yaml has been reorganised with clearer names for some of the options.
• Add interpolation method choice for galaxy and magnification bias

Full Changelog: v2026.02.0...v2026.02.1

v2026.02.0

Jaxified harmonic-space Gaussian covariance: now the code is ~10 times faster and can compute the 1/fsky Gaussian covariance over all integer ells in ~100s for 13 redshift bins and ell_max = 5000.

Full Changelog: v2026.01.2...v2026.02.0

v2026.01.2

The harmonic-space 1/fsky Gaussian covariance has been updated to provide higher numerical precision.

Previously, the covariance was calculated using the value $C_\ell$ at the bin center. The updated version computes the $C_\ell$ for every integer $\ell$ within falling within an $\ell$ bin and calculates their average. This approach is more accurate, as it doesn't assume the $C_\ell$ to be slowly-varying in the bin width.

NOTE: as the new, more precise binning is the default, this change will break compatibility with previous versions. To reproduce the old results, set in the config file

precision:
  cov_hs_g_ell_bin_average: False

v2026.01.1

Small bugfix: cloelib was imported even when not requiring the COSEBIs covariance. Fixed with a lazy import.

Full Changelog: v2026.01.0...v2026.01.1

v2026.01.0

This release introduces the $(E_n, B_n)$ (gaussian) COSEBIs covariance.
⚠️ Note: To compute this covariance, the code now requires cloelib as an additional dependency for calculating the COSEBIs filter functions.

Additional Changes:

• [Refactoring]: Implemented a CovarianceProjector parent class for CovRealSpace and CovCOSEBIs. This centralizes common computations and streamlines the individual classes.
• [Bugfixes]: Fixed a bug in the Shot Noise (SN) term of the 2PCF covariance that caused errors when ngal_lens != ngal_source.
• [Testing]: Implemented a more comprehensive regression test suite to ensure long-term stability and prevent future breaking changes.
