Galactic Component Classification For the all-sky PLATO Input Catalog

PLATO Targets Classification This repository contains the full list of PLATO targets, classified into their Galactic Component membership. The basis for the catalogue is the all-sky PLATO input catalog (asPIC) by Montalto2021, crossmatched with Gaia DR3. Files There are four files included in this repository: targets_classified: Description: The entire sample, classified into thin disk, thick disk candidate, thick disk, halo candidate, and halo. Note : Classification is only performed if relative uncertainties no greater than 20% in the following columns: "ra", "dec", "pmra", "pmdec", "parallax", and "radial_velocity". For targets where this requirement is not fulfilled, the related columns are filled with NaN. Format: 2,675,538 rows, 61 columns LOPS2: Description: A subselection of targets_classified in the LOPS2 field. Galactic Coordinates: l=255.9375°, b=-24.62432° Additional Column: "n_cameras" specifying the number of PLATO cameras that will observe the target. Format: 169,438 rows, 62 columns LOPN1: Description: A subselection of targets_classified in the LOPN1 field. Galactic Coordinates: l=81.56250°, b=24.62432° Format: 173,735 rows, 62 columns special_target_list: Description: A selection of 47 targets, kinematically classified as halo stars, within the high-SNR P1 PLATO sample. Additional Column: "n_cameras" specifying the number of PLATO cameras that will observe the target, and "Field" specifying if target belongs to LOPS2 or LOPN1 field Format: 47 rows, 63 columns Classification Criteria We classify only those stars into Galactic components that have relatively certain kinematic parameters. Specifically, we require no more than 20% relative uncertainty in the following columns: "ra", "dec", "pmra", "pmdec", "parallax", "radial_velocity". This results in 2,283,538 out of the total 2,675,539 stars having a component classification. Analysis Conditions For the analysis in our paper, we applied the following additional conditions: Population.notnull() Stellar type = FGK Radius > 0 Mass > 0 Teff > 0 Logg.notnull() [Fe/H].notnull() Applying these conditions results in 1,830,288 entries remaining.
