GCRCatalogs v1.9.0

Integrate (optional) use of the dataregistry as the repository for catalog metadata rather than the traditional method, which extracts metadata from catalog config files.

GCRCatalogs v1.8.0

Newly added catalogs

• roman_rubin_v1.1.3_elais: This catalog is a variant of roman_rubin_v1.1.2_elais that uses an improved tuning of the SED model parameters. The resulting luminosity distributions are in better agreement with the validation data (COSMOS 2020 and DESCQA tests).
• roman_rubin_v1.1.2_elais: This catalog was produced for the joint roman-desc image simulations using differentiable, forward modeling techniques. Predictions for the galaxy SEDs are based on their star-formation hsitories. Sky area covers the ELAIS field and is ~110 sq. deg.

(Thanks to @evevkovacs)

GCRCatalogs v1.7.0

Newly added catalogs

• roman_rubin_2023_v1.1.1_elais: This is the 110 sq. deg. extra-galactic catalog covering the ELAIS field for the Roman-Rubin image simulations for LSST DESC that has been created with fully forward modeled SEDs (thanks to @evevkovacs)

Full Changelog: v1.6.0...v1.7.0

GCRCatalogs v1.6.0

This release includes new "SkySim" galaxy catalog (also known as DiffSky; Not to be confused with the SkySim5000 catalog series), and new versions of the "SkySim5000" catalogs.

Newly added catalogs

• skysim_v3.1: prototype of new galaxy catalog (also known as DiffSky) produced with differentiable, forward modeling techniques, sky area (~400 sq. deg.). Not to be confused with the SkySim5000 catalog series.
• skysim5000_v1.2: latest SkySim5000 catalog, with bug fixes for ellipticity and concentration values; tidal torque fields added, full sky area (~5000 sq. deg.)
• skysim5000_v1.2_image: same but only covers the image simulation sky area (~400 sq. deg.)
• skysim5000_v1.2_small: same but only covers a small sky area (~50 sq. deg.) for testing purposes
• skysim5000_v1.1.2: preliminary version of new SkySim5000 catalog, full sky area (~5000 sq. deg.) (0<z<1)

GCRCatalogs v1.5.0

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.

GCRCatalogs v1.4.2

This is bug-fix release.

• desc_dc2_run2.2i_dr6_object and desc_dc2_run2.2i_dr6_v4_object now point to the correct path for public users. Thanks to @nevencaplar for catching this.

GCRCatalogs v1.4.1

GCRCatalogs v1.4.1 includes an update to the skysim5000 catalog and also the WaZP cluster catalog for cosmoDC2.

Newly added catalogs

• cosmoDC2_v1.1.4_wazp_v1.0_truez: WaZP cluster catalog (v1.0) for cosmoDC2 v1.1.4 using true redshifts. (Thanks to @m-aguena)
• cosmoDC2_v1.1.4_wazp_v1.0_flexzboost_v1: WaZP cluster catalog (v1.0) for cosmoDC2 v1.1.4 using FlexZBoost redshifts. (Thanks to @m-aguena)
• skysim5000_v1.1.2: latest SkySim5000 catalog, full sky area (~5000 sq. deg.) for 0<z<1 only. For z > 1, one should continue using v1.1.1. Thanks to @evevkovacs)

GCRCatalogs v1.4.0

GCRCatalogs v1.4.0 includes updated truth catalogs for both DESC internal use and public release (@JoanneBogart @jchiang87 @yymao @heather999). In addition, redmagic catalogs for cosmoDC2 and DC2 are available for DESC internal use (@erykoff). See below for a complete list.

New/updated catalogs for DESC internal use

Truth catalogs

• dc2_run2.2i_truth_galaxy_summary: points to v1.0.0
• dc2_run2.2i_truth_sn_summary: points to v1.0.0
• dc2_run2.2i_truth_sn_variability: points to v1.0.0
• dc2_run2.2i_truth_star_summary: points to v1.0.0
• dc2_run2.2i_truth_star_variability: points to v1.0.0

• dc2_object_run2.2i_dr6_v2_with_addons_v1
• dc2_object_run2.2i_dr6_v2_with_addons_v2

Note that the catalogs that start with dc2_run2.2i_truth_ are intended to replace existing catalogs that start with dc2_truth_run2.2i_. See the deprecated catalogs section for details.

People who are using dc2_object_run2.2i_dr6_v2_with_addons should test their code with dc2_object_run2.2i_dr6_v2_with_addons_v2, because in the future, the former will point to the latter. If you need the columns that are only available in the current version of dc2_object_run2.2i_dr6_v2_with_addons, switch to using dc2_object_run2.2i_dr6_v2_with_addons_v1 in your code.

Redmagic catalogs

• cosmoDC2_v1.1.4_redmagic_v0.8.1_highdens
• cosmoDC2_v1.1.4_redmagic_v0.8.1_highlum
• dc2_redmagic_run2.2i_dr6_wfd_v0.8.1_highdens
• dc2_redmagic_run2.2i_dr6_wfd_v0.8.1_highlum

Deprecated catalogs DESC internal use

• All catalogs start with dc2_truth_run2.2i_. Use dc2_run2.2i_truth_* instead.
• dc2_object_run2.2i_dr6_v2_with_addons will point to dc2_object_run2.2i_dr6_v2_with_addons_v2 in the future, please update your code accordingly. If you need the columns that are only available in dc2_object_run2.2i_dr6_v2_with_addons, switch to using dc2_object_run2.2i_dr6_v2_with_addons_v1.

New/updated catalogs for public release

• desc_dc2_run2.2i_dr6_object_with_truth_match: now points to desc_dc2_run2.2i_dr6_v4_object_with_truth_match

If you need previous (and now deprecated) versions of desc_dc2_run2.2i_dr6_truth, desc_dc2_run2.2i_dr6_object, or desc_dc2_run2.2i_dr6_object_with_truth_match, please specify the version in the catalog names (see the section below).

Deprecated catalogs public release

• desc_dc2_run2.2i_dr6_v1_object

• desc_dc2_run2.2i_dr6_v2_object_with_truth_match
• desc_dc2_run2.2i_dr6_v2_truth

Use desc_dc2_run2.2i_dr6_truth, desc_dc2_run2.2i_dr6_object, and desc_dc2_run2.2i_dr6_object_with_truth_match instead (all point to v4 currently)
