cds-question@unistra.frgalaxiesabsolute-magnitudeStars do not form continuously distributed over star-forming galaxies. They form in star clusters of different masses. This nature of clustered star formation is taken into account in the theory of the integrated galactic stellar initial mass function (IGIMF) in which the galaxy-wide initial mass function (IMF) on galaxy-wide scales is calculated by adding all IMFs of young star clusters. For massive stars, the IGIMF is steeper than the universal IMF in star clusters and steepens with decreasing star formation rate (SFR) which is called the IGIMF effect. The current SFR and the total H{alpha} luminosity of galaxies therefore scale nonlinearly in the IGIMF theory compared to the classical case in which the galaxy-wide IMF is assumed to be constant and identical to the IMF in star clusters. Here we apply for the first time the revised SFR-L_H{alpha}_ relation on a sample of local volume star-forming galaxies with measured H{alpha} luminosities.2009ApJ...706..516Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/706/516CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/167 : Atlas of UV spectra of star-forming galaxies (Kinney+ 1993)J/other/Ser/179.87 : H{alpha} in HII regions of Holmberg IX (Arbutina+, 2009)J/A+A/476/1161 : Spitzer photometry of M33 (Verley+, 2007)J/ApJS/164/81 : Spectrophotometry of nearby galaxies (Moustakas+, 2006)J/AJ/132/271 : SFR of M31 from resolved stars in near-IR (Olsen+, 2006)J/MNRAS/338/525 : Recent star formation in UCM galaxies (Perez-Gonzalez+,https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/706/516https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/706/516http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/706/516https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/706/516https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/706/516http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/706/516GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/706/516/table1 (Galaxy properties)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/706/516/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/706/516/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/706/516/table1?GETtext/xml+votable180.050000true151.16987529.36441670.0055555555555555566/941 955 2130 2155 2169 2709 3042 3381 3543 3573 4038 5132 5142 5174 5285 5287 5489 5584 5607 5710 5978 6027 6320 6443 6623 7022 7471 7523 7530 7577 7582 7600 7602-7604 7606-7607 7618 7622 7624 7649-7650 7687 7743 7769 7786 7799 7878 7946 7956 7970 8028 8120 8327 8908 9277 9361 9855 10153 10265 10350 10532 10538 10601 10607 10627 10659 10704 10761-10762 10778 10793 10798 10800 10809-10810 10818 10847 10856 10881 10888 10905 10908 10910-10911 10941 10945 10954 10959 10970 10977 10999 11006 11019 11027 11030 11041 11043 11045 11084 11092-11093 11120 11127 11227 11434 11444 11448 11450 11612 11696 11719 11769 11933 11944 11961 12231 12372 12615 13391 16384 16416 16519 16687 16695 16697 16779 17165 17745 18041 18287 18315 18378 18429 18649 19125 19570 19758 19779 19843 19990 20065 20400 20476 26858 27199 27351 27383 27926 28015 28087 28149 28151 28476 28486 28493 28510 28535 28631 28636-28637 28666 29699 29718 32282 33096 33317 35214 35243 35514 35578 36054 38846 46545 48942https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/706/516?format=asciiOpticaldefaultJ/ApJ/706/516/table1Galaxy propertiesrecnoRecord number assigned by the VizieR team.
