cds-question@unistra.frsurveysgalaxiesphotometrychemical-abundancesextinctionWe present the panchromatic spectral energy distributions (SEDs) of the Local Volume Legacy (LVL) survey which consists of 258 nearby galaxies (D<11Mpc). The wavelength coverage spans the ultraviolet to the infrared (1500{AA}-24{mu}m) which is utilized to derive global physical properties (i.e. star formation rate, stellar mass, internal extinction due to dust). With these data, we find colour-colour relationships and correlated trends between observed and physical properties (i.e. optical magnitudes and dust properties, optical colour and specific star formation rate, and ultraviolet-infrared colour and metallicity). The SEDs are binned by different galaxy properties to reveal how each property affects the observed shape of these SEDs. In addition, due to the volume-limited nature of LVL, we utilize the dwarf-dominated galaxy sample to test star formation relationships established with higher mass galaxy samples. We find good agreement with the star-forming `main-sequence' relationship, but find a systematic deviation in the infrared `main sequence' at low luminosities. This deviation is attributed to suppressed polycyclic aromatic hydrocarbon (PAH) formation in low-metallicity environments and/or the destruction of PAHs in more intense radiation fields occurring near a suggested threshold in star formation rates (sSFR) at a value of log(sSFR)~-10.2.2014MNRAS.445..899Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/445/899CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/703/517 : The Spitzer Local Volume Legacy: IR photometry (Dale+, 2009)J/MNRAS/445/881 : LVL global optical photometry (Cook+, 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/445/899https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/445/899http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/445/899https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/445/899https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/445/899http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/445/899GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/445/899/table1 (General galaxy properties)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/445/899/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/445/899/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/445/899/table1?GETtext/xml+votable180.050000true0.4923333-15.46091670.0055555555555555566/396 764 2121 2130 2155 2282 4181 4511 5061 5067 5116 5132 5142 5174 5202-5203 5230 5283 5287 5329 5504 5584 5607 5636 5978 6502 6604-6605 6623 6649 7239 7471 7523 7530 7577 7582 7599-7600 7602-7604 7606-7607 7618 7622 7624 7649-7650 7743 7769 7786 7799 7878 7946 7956 7970 8120 8908 10153 10265 10532 10538 10561 10607 10627 10659 10755 10761-10762 10767 10793 10798-10800 10809 10818 10840-10841 10847 10856 10881 10888 10896-10897 10900-10901 10905 10908 10910-10911 10935 10941 10954 10959 10970 10976-10977 10979 10986 10998-10999 11006 11019 11027 11030 11045 11084 11092 11120 11127 11140 11143 11227 11434 11444 11448 11639 11681 11696 11933 11944 11961 11965 12047 12199 13637 16441 16459 16519 16544 16595 16605 16655 16682 16695 16697 16701 16744 16779 16833 17165 18032 18041 18378 18398 18419 18429 19717 19779 19990 21026-21027 24912 24952 24956 25017 25083 26047 26814 26858 26977 27030 27055 27351 27375 27383 27465 27512 27514 27568 27591 27604 27643 27926 28015 28087 28091 28149 28167 28172-28173 28184 28451 28468 28510 28535 28608 28610 28631 28636-28637 28666 33096 33151 33193 33265 33295 33571 33655-33656 33685 33832 33927 33966 33986 34297 34401 34403-34404 34471 34641 35206 35214 35243 35482 35514 35536 36164 38841 38846 43706 43874 43878 43881 43883 43925 43972 45305 45367 45777 45914 45937 46339 46460 46545 46549 46597 48942https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/445/899?format=asciiOpticaldefaultJ/MNRAS/445/899/table1General galaxy propertiesSimbadNameSimbad column added by the CDSmeta.idcharDEJ2000Declination (J2000)pos.eq.dec;meta.mainrecnoRecord number assigned by the VizieR team.
