The mean_delta_sigma function should give identical results if the particles are divided in half and the results on the two halves are summed at the end. As pointed out by...

WIP PR resolving #993

Thanks to @jmsull for helping track this down. This WIP PR is getting close but is not quite there. Fix #933

Relax requirement for consistency between halo mass and radius

Thanks to @jmsull and @rainwoodman for pointing out the problem this is causing in https://github.com/bccp/nbodykit/issues/634.

As pointed out by @Christopher-Bradshaw in #962 (and also https://github.com/manodeep/Corrfunc/pull/201), the `angular_tpcf` function appears to have an incorrect factor of Nr x Nr instead of Nr x (Nr-1). This has...

The current OccupationTemplate class requires that all HOD models define a threshold attribute. This is inappropriately restrictive since it is commonplace for HOD models to be applied to color-selected samples.

Currently the mean_delta_sigma only has unit-testing, but there is no scientific validation is done.

1-halo delta sigma has incorrect asymptotic behavior

1

The implementation of the 1-halo decomposition of the delta sigma function merged in #955 does not fall off to zero for R_p > Rvir, which cannot be correct.

Review API of new satellite rotations module

1

Ensure that the current API of the satellite rotations module introduced in PR #905 is the most useful formulation for intrinsic alignment modeling, and also synthetic satellite/subhalo additions/transfer. In particular,...
