title: Catalogues containing photometry in 22 passbands for  603311 LMC stars and 124578 SMC stars from Bellazzini & Pascale 2024, A&A,

description: Catalogues from the paper "The RGB Tip in the SDSS, PS1, JWST, NGRST and Euclid photometric systems. Calibration in optical passbands using Gaia DR3 synthetic photometry" by M. Bellazzini (INAF - OAS Bo) & R. Pascale (INAF - OAS Bo), A&A, in press, (arXiv:2406.04781).  Stars have been selected from the Gaia DR3 dataset and the magnitudes has been obtained from the Gaia GSPC catalogue of from GaiaXPy as described in Gaia Collaboration 2023.

Each catalogue contains:

 





Column 1-15, parameters directly extracted from the Gaia DR3 source catalogue, namely: source_id, ra, dec, parallax, parallax_error, pmra, pmra_error, pmdec, pmdec_error, ruwe, phot_variable_flag, and non_single_star.

Column 16: C⋆, a parameter that is derived from phot_bp_rp_excess_factor (that, in turn, has been extracted from the Gaia DR3 source catalogue) following (Riello et al. 2021).

Column 17: colour excess E(B-V), derived from Skowronet al. (2021) and Schlegel et al. (1998); Schlafly & Finkbeiner (2011) as described in Sect. 2.

Columns 18-27: standardised ugriz magnitudes in the SDSS system extracted from the Gaia DR3 GSPC (Gaia Collaboration et al. 2023a) and associated uncertainties.

Columns 28-37: standardised UBVRI magnitudes in the JKCsystem extracted from the Gaia DR3 GSPC (Gaia Collaboration et al. 2023a) and associated uncertainties.

Columns 38-47: standardised grizy magnitudes in the PS1 system computed with GaiaXPy and associated uncertainties.

Columns 48-51: standardised F606W, F814W magnitudes in the HST ACS-WFC system extracted from the Gaia DR3 GSPC (Gaia Collaboration et al. 2023a) and associated uncertainties.

Columns 52-55: non-standardised F070W and F090W magnitudes in the JWST-NIRCAM system computed with GaiaXPy and associated uncertainties.

Columns 56-59: non-standardised R062 and Z087 magnitudes in the NGRST system computed with GaiaXPy and associated uncertainties .

Columns 60-61: non-standardised I_E magnitude in the Euclid-VIS system computed with GaiaXPy and associated uncer-tainties (in this case, not corrected for the bias described in Sect. 2.1 of Gaia Collaboration et al. 2023a, hence slightly underestimated).


It is very important to remind that u_SDSS and U_JKC magnitudes from Gaia XPSP are significantly less accurate and pre-cise than all the other magnitudes included in our catalogues (see Gaia Collaboration et al. 2023a, for detailed discussion).Each star can lack some of the 22 magnitudes listed in the catalogues, depending on the signal-to-noise constraints applied to the original GSPC (S/N> 30 Gaia Collaboration et al. 2023a). For example, of the 603311 stars listed in the LMC sample only 83229(85338) have valid u_SDSS (U_JKC ) magnitudes. See Bellazzini & Pascale 2024 for further details and references.


We cannot give any hint or guarantee on the behaviour of the completeness of the samples as a function of the various magnitudes and colours, as well as as a function of position in the sky (see Bellazzini & Pascale 2024 for details on the selections applied).
