glass 2023.6 (30 Jun 2023)

• There is some support for simulating the deflections due to weak gravitational lensing:

  • The deflect() function applies deflections to positions.

  • The from_convergence() function returns one or more other lensing fields given the convergence.

  • The shear_from_convergence() function is deprecated in favour of from_convergence().

• The glass module is no longer a namespace package. The new glass.ext namespace is reserved for extensions instead. This is done to follow best practices, so that a bad extension can no longer break all of GLASS by mistake. The glass.all meta-module is no longer necessary.

• The point sampling functions positions_from_delta() and uniform_positions() now return an iterator over points. This has lead to orders-of-magnitude improvements in memory use and performance when simulating galaxies at Euclid/LSST densities.

• The ellipticity sampling functions ellipticity_gaussian() and ellipticity_intnorm() accept array inputs.

• A bug causing incorrect results from effective_bias() has been fixed.
