ADC_Keywords: Galaxies, nearby ; Galaxies, photometry Keywords: galaxies: photometry - galaxies: general - techniques: photometric - dust, extinction - surveys - catalogues Abstract: The DustPedia project is capitalising on the legacy of the Herschel Space Observatory, using cutting-edge modelling techniques to study dust in the 875 DustPedia galaxies - representing the vast majority of extended galaxies within 3000km/s that were observed by Herschel. This work requires a database of multiwavelength imagery and photometry that greatly exceeds the scope (in terms of wavelength coverage and number of galaxies) of any previous local-Universe survey. We constructed a database containing our own custom Herschel reductions, along with standardised archival observations from GALEX, SDSS, DSS, 2MASS, WISE, Spitzer, and Planck. Using these data, we performed consistent aperture-matched photometry, which we combined with external supplementary photometry from IRAS and Planck. We present our multiwavelength photometry across 40 UV-microwave bands for the 875 DustPedia galaxies. Our aperture-matched photometry, combined with the external supplementary photometry, represents a total of 21,857 photometric measurements. A typical DustPedia galaxy has multiwavelength photometry spanning 25 bands. To carry out our photometry we developed the Comprehensive & Adaptable Aperture Photometry Routine (CAAPR). CAAPR is designed to produce consistent photometry for the enormous range of galaxy and observation types in our data. In particular, CAAPR is able to determine robust cross-compatible uncertainties, thanks to a novel method for reliably extrapolating the aperture noise for observations that cover a very limited amount of background. Description: These tables contain multiwavelength photometry for the 875 DustPedia galaxies, spanning 40 photometric bands. Aperture-matched photometry, performed using the CAAPR pipeline, is provided for 27 bands (from GALEX, SDSS, 2MASS, WISE, Spitzer, and Herschel). Ancillary photometry from IRAS SCANPI and Planck CCS2. Images available in FITS format from the DustPedia database (http://dustpedia.astro.noa.gr). File Summary:

Note (1): Quantities from NED (https://ned.ipac.caltech.edu/) Note (2): Quantities from HyperLEDA (http://leda.univ-lyon1.fr/) Note (3): Our preferred distance estimates are the redshift-independent distances provided by the HyperLEDA database, as these have been homogenised to account for methodological differences between references. For galaxies without redshift-independent HyperLEDA distances, our next preferred values are the redshift-independent distances provided by the Nasa/ipac Extragalactic Database (NED); whilst these are not homogenised like the HyperLEDA values, we take the quoted average value for each galaxy to minimise bias. If neither HyperLEDA nor NED redshift-independent distances are available for a source, we use the flow-corrected redshift-derived values provided by NED these distances were calculated assuming a Hubble constant of H0=73.24km/s/Mpc (Riess et al. 2016, Cat. J/ApJ/826/56), and have been corrected for bulk deviation from Hubble flow arising from the influence of the Virgo Cluster, the Great Attractor, and the Shapley Supercluster (Mould et al. 2000ApJ...529..786M).

Global notes: Note (G1): Flags (full explanations in Sections 4 and 5 of paper) as follows: A = Artefact flag. This indicates that some sort of map artefact is present in the region of the target source, as determined by visual inspection. Examples of this include poor mosaicing in the archival data, satellite trails, or evidence of saturation in bright pixels, upper case. a = Artefact flag. This indicates that some sort of map artefact is present in the region of the target source, as determined by visual inspection. Examples of this include poor mosaicing in the archival data, satellite trails, or evidence of saturation in bright pixels, lower case. C = Contamination flag. This indicates contamination of the photometry due to a nearby source, as determined by visual inspection. Examples of this include foreground stars that were not fully removed, or other galaxies close to the target source, upper case. c = Contamination flag. This indicates contamination of the photometry due to a nearby source, as determined by visual inspection. Examples of this include foreground stars that were not fully removed, or other galaxies close to the target source, lower case. N = Null-coverage flag. This flag is automatically assigned where necessary. This indicates that the observation didn't provide full coverage of the area of the source, limiting CAAPR's ability to suitably measure the source flux and/or background. If more than 20% of the pixels in the master aperture and/or more than 60% of the pixels in the background annulus are found to be NaN, a major flag is raised. Instruments for which small maps are common (such as Spitzer and PACS) are particularly likely to have fluxes with this flag. n = Null-coverage flag. This flag is automatically assigned where necessary. This indicates that the observation didn't provide full coverage of the area of the source, limiting CAAPR's ability to suitably measure the source flux and/or background. If more than 5% of the pixels in the master aperture and/or more than 20% of the pixels in the background annulus are found to be NaN - 'Not a Number' - then a minor flag is raised. E = Excluded extended emission flag. This flag is only used with our supplementary photometry (as described in Section 5), and is not assigned to any of our aperture-matched CAAPR fluxes. It indicates that the target is sufficiently extended that there is a risk some of its emission will have been excluded from the measurement in question, which would lead to the flux being an under-estimate, upper case. e = Excluded extended emission flag. This flag is only used with our supplementary photometry (as described in Section 5), and is not assigned to any of our aperture-matched CAAPR fluxes. It indicates that the target is sufficiently extended that there is a risk some of its emission will have been excluded from the measurement in question, which would lead to the flux being an under-estimate, lower case. Note (G2): Quoted uncertainties incorporate instrumental calibration uncertainties.
