This release includes new redmapper and redmagic catalogs, a backward-incompatible change on the cosmoDC2 position angles (see below for details), and a few minor bug fixes.

Newly added catalogs

  • skysim5000_v1.1.1_redmapper_v0.8.5: Redmapper catalog (v0.8.5) for skysim5000_v1.1.1
  • skysim5000_v1.1.1_redmagic_v0.8.5_highdens: Redmagic catalog (v0.8.5) for skysim5000_v1.1.1 for the high density sample
  • skysim5000_v1.1.1_redmagic_v0.8.5_highlum: Redmagic catalog (v0.8.5) for skysim5000_v1.1.1 for the high luminosity sample
    (Thanks for @erykoff for providing the above catalogs)

cosmoDC2 position angles

Note the both the changes described below are not backward-compatible. However, additional quantities are provided to maintain backward-compatibility. Change your code if you require the old behaviors.

Changes in values

The default values for position_angle in the cosmoDC2 catalog have changed from this version going forward. The values of position_angle are now derived from the native quantity morphology/positionAngle, rather than random values generated by the GCR reader that were used for DC2. The former values are still available as position_angle_true_dc2.

Changes in definition

Furthermore, the sign convention for position_angle has flipped and now increases to the East. The previous versions used the phosim convention (increasing to the West). The phosim convention values are available as position_angle_true_phosim. Note also that, because position_angle is used in the definition of the ellipticity components, these quantities have also changed. The quantities ellipticity_1_true_dc2 and ellipticity_2_true_dc2 supply the legacy values used for DC2.
