The need for recovering the light reprocessed by dust commonly requires the use of low spatial resolution far-infrared data. Recombination line luminosities provide an alternative, although uncertain dust-extinction corrections based on narrowband imaging or long-slit spectroscopy have traditionally posed a limit to their applicability. Integral field spectroscopy (IFS) is clearly the way to overcome this kind of limitation. We obtain integrated H{alpha}, ultraviolet (UV) and infrared (IR)-based SFR measurements for 272 galaxies from the CALIFA survey at 0.005<z<0.03 using single-band and hybrid tracers. We aim to determine whether the extinction-corrected H{alpha} luminosities provide a good measure of the SFR and to shed light on the origin of the discrepancies between tracers. Updated calibrations referred to H{alpha} are provided. The well-defined selection criteria and large statistics allow us to carry out this analysis globally and split by properties, including stellar mass and morphological type. We derive integrated, extinction-corrected H{alpha} fluxes from CALIFA, UV surface and asymptotic photometry from GALEX and integrated WISE 22{mu}m and IRAS fluxes. We find that the extinction-corrected H{alpha} luminosity agrees with the hybrid updated SFR estimators based on either UV or H{alpha} plus IR luminosity over the full range of SFRs (0.03-20M_{sun}_/yr). The coefficient that weights the amount of energy produced by newly-born stars that is reprocessed by dust on the hybrid tracers, a_IR_, shows a large dispersion. However, this coefficient does not became increasingly small at high attenuations, as expected if significant highly-obscured H{alpha} emission were missed, i.e., after a Balmer decrement-based attenuation correction is applied. Lenticulars, early-type spirals, and type-2 AGN host galaxies show smaller coefficients because of the contribution of optical photons and AGN to dust heating. In the local Universe, the H{alpha} luminosity derived from IFS observations can be used to measure SFR, at least in statistically-significant, optically-selected galaxy samples, once stellar continuum absorption and dust attenuation effects are accounted for. The analysis of the SFR calibrations by galaxies properties could potentially be used by other works to study the impact of different selection criteria in the SFR values derived, and to disentangle selection effects from other physically motivated differences, such as environmental or evolutionary effects.2015A&A...584A..87Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/584/A87CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/573/A59 : Gas kinematics in CALIFA survey (Garcia-Lorenzo+, 2015)J/A+A/576/A135 : CALIFA DR2 (Garcia-Benito+, 2015)J/A+A/581/A103 : CALIFA survey across the Hubble sequence (Gonzalez+, 2015)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/584/A87https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/584/A87http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/584/A87https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/584/A87https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/584/A87http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/584/A87GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/584/A87/table1 (Integrated measurements for the CALIFA galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/584/A87/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/584/A87/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/584/A87/table1?GETtext/xml+votable180.050000true0.33237534.52574440.0055555555555555566/56 554 721 738 909 995 2206 2229 2248 2251 2254 2272-2274 2290 2641 4053 4167 4178 4342 4445 4454 4477 4507 4511 4813 4912 4950 4993 5247 5298 5332 5505 5533 5579 5593 5704 6216 6240-6241 6261 6342 6362 6366 6977 7204 7214 7309 7824 7844 8045 8331 8458 8480 8492 8498 8522 8536 8552 8562-8563 8621 8646 8673 8743 8752 8883 8919 8921 8973 9098 9101 9124 9187 9216 9220 9381 9622 9628 9718 9798 9859 9875 9882-9883 9885 9891 9974 10025 10111 10113 10183 10200 10213 10220-10221 10280 10286 10380-10381 10398 10422 10434 10448 10485 10511 10515 10518-10519 10524 10566 10570 10577 10583 10586 10588 10595 10609 10612 10621 10627-10629 10661-10662 10674 10705 10711 10719 10739-10740 10778 10846 10987 11070 11112 11164 11196 11272 11290 11342 11369 11372 11374 11377 11383 11392 11396 11451 11544 11832 11944 12306 12378 12709 13316 13381 13426 15004 16702 16787-16788 16793 17234 17238 17350 17398 17486 17492 17751 17819 17912 18069 18071 18081 18173 18252 18300 18381 18383 18523 18775 18779 18781 18800 18838 18854 18932 18941 19027 19073 19108 19186 19227 19260 19267 19458 19487 19489 19508 19515 19537-19538 19593 19618 19633 19696 19749 19848 19939-19940 19954 19983 19991 19996-19997 20009 20020 20023 20031 20040 20193 20254 20279 20417-20418 20429 22737 22741 23337 23353 23401 26495 26551 27559 27567 27719 27748 28322 28430 28458 28491 28513 28522 28579 28617 29973 31546 31628 31642 31688-31689 31736 32478 32482 32559 48880 49121 49150https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/584/A87?format=asciiOpticalUVInfrareddefaultJ/A+A/584/A87/table1Integrated measurements for the CALIFA galaxiesSimbadNameSimbad column added by the CDSmeta.idcharNameGalaxy namemeta.id;meta.maincharIDCALIFA identifiermeta.idintrecnoRecord number assigned by the VizieR team.
