Description

Table 1 in Manea et al. 2023: Chemical Doppelgangers in GALAH DR3: the Distinguishing Power of Neutron-Capture Elements Among Milky Way Disk Stars (https://ui.adsabs.harvard.edu/abs/2023arXiv231015257M/abstract)

These files contain the parameter and abundance results of our Cannon run on GALAH DR3 giants.  manea_et_al_2023.fits contains the results without censoring applied, and manea_et_al_2023_censoring.fits contains the results with censoring applied.  The latter file is provided solely for reader interest, but the former file is what we use for our measurement of the doppelganger rate in GALAH DR3.  We strongly urge users to only consider abundances with X_fe_cannon_chisq < 2 as these abundances are considered reliable (see Section 3.1.4).  Entries with empty abundance uncertainties correspond to extremely poorly-fit abundances and should be ignored by the user, and employing the X_fe_cannon_chisq < 2 will already remove these.

Please see Table 1 in Manea et al. 2023 for the table schema.
