cds-question@unistra.frgalactic-centergalaxy-rotationgalaxiesphotometryastronomical-modelsMaximum disc decompositions of rotation curves place a dynamical upper limit to the mass attributable to stars in galaxies. The precise definition of this term, however, can be vague and varies in usage. We develop an algorithm to robustly quantify maximum-disc mass models and apply it to 153 galaxies from the Spitzer Photometry and Accurate Rotation Curve data base. Our automatic procedure recovers classic results from manual decompositions. High-mass, high-surface-brightness galaxies have mean maximum-disc mass-to-light ratios of ~0.7M_{sun}_/L_{sun}_ in the Spitzer 3.6{mu}m band, which are close to the expectations from stellar population models, suggesting that these galaxies are nearly maximal. Low-mass, low-surface-brightness galaxies have very high maximum-disc mass-to-light ratios (up to 10M_{sun}_/L_{sun}_), which are unphysical for standard stellar population models, confirming they are sub-maximal. The maximum-disc mass-to-light ratios are more closely correlated with surface brightness than luminosity. The mean ratio between baryonic and observed velocity at the peak of the baryonic contribution is Vbar/Vp~0.88, but correlates with surface brightness, so it is unwise to use this mean value to define the maximum disc concept. Our algorithm requires no manual intervention and could be applied to large galaxy samples from future HI surveys with Apertif, Askap, and SKA.2018MNRAS.480.2292Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/480/2292CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/480/2292https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/480/2292http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/480/2292https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/480/2292https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/480/2292http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/480/2292GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/480/2292/table1a (SPARC: Mass Models for 175 Disk Galaxies with Spitzer Photometry and Accurate Rotation Curves (Galaxy Supplement))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/480/2292/table1a?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/480/2292/table1a?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/480/2292/table1a?GETtext/xml+votable180.050000true0.49125-15.46388890.0055555555555555566/816 955 975 1007 1114 1561 2071 2169 2351 2383 2409 2866 3436 3511 3519 4447 4511 4522 4534 4554 4650 4689 4691 4695 4811 5067 5124 5129 5131 5168 5174 5230 5329 5463 5469 5500 5503-5504 5581 5584 5587 5589 5591 5594 5596 5599 5623 5625 5628-5629 5631 5636 5669 5710 5751 5827 5956 5967 5975 5982 6604 6623 7132 7241 7303 7523 7602 7624 7743 7799 7878 7882 7946 7957 8552 8557 8827 9097 9463 9855 10282 10286 10475 10511 10637 10662 10689 10809 10817 10841 10847 10881 10908 10910 10924-10925 10927 10930 10935 10941 10955 10970 10976 10979 10990-10991 11000 11006 11019 11030 11092 11127 11375 11389 11448 11566 11639 11696 12570 13489 13522 13668 15551 15592 15594 16016 16083 16441 16519 16595 16701 17165 17753 18315 18378 19570 19697 19843 20020 20353 20438 24952 26106 27030 27468 28077 28087 28102 28107 28149 28230 28259 28261 28346 28463 28496 28535 28631 28637-28638 32231 33435 33589 33986 35514 35536 35746 36974 38846 40531 43972https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/480/2292?format=asciidefaultJ/MNRAS/480/2292/table1aSPARC: Mass Models for 175 Disk Galaxies with Spitzer Photometry and Accurate Rotation Curves (Galaxy Supplement)SimbadNameSimbad column added by the CDSmeta.idcharnullableLbulgeBulge Luminosity at 3.6{mu}m1e+09solLumphys.luminosity;em.IRfloatReffEffective Radius at 3.6{mu}mkpcphys.size.radiusfloatRpRadius of peak Vbarkpcphys.size.radiusfloatSBeffEffective Surface Brightness at 3.6{mu}msolLum.pc**-2phot.mag.sb;em.IR.3-4umdoublee_SBeffUncertainty in SBeffsolLum.pc**-2stat.errorfloatRdiskDisk Scale Length at 3.6{mu}mkpcphys.size.radiusfloatSB0Disk Central Surface Brightness at 3.6{mu}msolLum.pc**-2phot.mag.sb;em.IR.3-4umdoublee_SB0Uncertainty in SBdisksolLum.pc**-2stat.errorfloatMbarBaryonic mass (2)1e+09solMass.pc**-2phys.massfloate_MbarUncertainty in Mbar (2)1e+09solMass.pc**-2stat.errorfloatSBbarBaryonic Surface Brightness at 3.6{mu}m (2)solLum.pc**-2phot.mag.sb;em.IR.3-4umdoublee_SBbarUncertainty in SBbar (2)solLum.pc**-2stat.errordoubleVobspObserved circular velocity at Rp (2)km/sphys.velocfloate_VobspUncertainty in Vobsp (2)km/sstat.errorfloatVbarpTotal baryonic velocity at Rp (2)km/sphys.velocfloate_VbarpUncertainty in Vbarp (2)km/sstat.errorfloat_RARight Ascension (J2000) from SIMBAD (not part of the original data)degpos.eq.ra;meta.main_DEDeclination (J2000) from SIMBAD (not part of the original data)degpos.eq.dec;meta.mainrecnoRecord number assigned by the VizieR team.
