This release is the same as the previous (2024.01.24) one. It was created so that Zenodo can sync and assign a DOI for this repository.

Catalogue created on 2024-01-24 (YYYY-MM-DD)

Changelog:

  • Fix: objects from SDSS BOSS were not being added to the final catalogue
  • Changes on how data is sorted before duplicate removal
    • Before: the data would be split into blocks and each block was sorted using the spectroscopic redshift error.
    • After: two new auxiliary columns are created, related to the spectroscopic classification and redshift flags. Each block is then sorted with the following priority: Spectroscopic class > Spectroscopic redshift flag > Spectroscopic redshift error.
    • The sorting done in the class has the following order: GALAXY > AGN > SUPERNOVAE > QSO > STAR > GLOBCLUSTER > UNCLEAR.
    • For the spectroscopic redshift flag, the sorting order is: KEEP > REMOVE > Unavailable.
  • With these changes, we avoid the problem of removing objects that have classifications and/or good redshifts but higher redshift errors when there is a duplicate object with lower errors but UNCLEAR classes and/or REMOVE redshift flags.
