Physical properties of star-forming clumps in nearby galaxies from CLAUDS and HSC-SSP

This repository contains the data released in the following publications: 'The fraction of clumpy star-forming galaxies in nearby galaxies from CLAUDS and HSC-SSP' (doi: will follow) 'Physical properties of star-forming clumps in nearby galaxies from CLAUDS and HSC-SSP' (doi: will follow) The catalogues contain the clumps' coordinates together with measured fluxes and magnitudes for each of the ugrizy-filter bands measured from the CLAUDS and HSC-SSP science images and the larger set of clumps from the HSC-SSP Wide survey with only grizy-photometry. The catalogues also contain estimates for the stellar mass, age, metallicity and dust attenuation of the clumps which we inferred through SED fitting. We will release updates if needed via Zenodo versioning. We recommend using the latest version of this repository. You can check the version you are currently viewing on the right-hand sidebar. Please cite the above mentioned publications when using the data in this repository. The data is stored in two different file-formats, as a FITS-table and a Pandas dataframe in a compressed parquet-file. The files have the following columns: Field Description Units Source HSCobjid HSC-SSP PDR3 Object-ID HSC-SSP PDR3 bbox_id Bounding box-ID clump_id Clump-ID objectness Objectness score clump_ra Right Ascension Degrees clump_dec Declination Degrees clump_aper_corr_(u|g|r|i|z|y) Aperture correction factor clump_flux_nJy_(u|g|r|i|z|y) Measured flux nJy clump_flux_nJy_err_(u|g|r|i|z|y) Error measured flux nJy clump_flux_nJy_bkgsub_(u|g|r|i|z|y) Bkg.-subtracted flux nJy clump_flux_nJy_err_bkgsub_(u|g|r|i|z|y) Error bkg.-subtracted flux nJy clump_flux_ABmag_(u|g|r|i|z|y) Clump magnitude (measured) $m_{\mathrm{AB}}$ clump_flux_ABmag_err_(u|g|r|i|z|y) Error clump magnitude (measured) $m_{\mathrm{AB}}$ clump_flux_ABmag_bkgsub_(u|g|r|i|z|y) Clump magnitude (bkg.-subtracted) $m_{\mathrm{AB}}$ clump_flux_ABmag_err_bkgsub_(u|g|r|i|z|y) Error clump magnitude (bkg.-subtracted) $m_{\mathrm{AB}}$ clump_flux_ABmag_bkgsub_corr_(u|g|r|i|z|y) Clump mag.
