Our spatially resolved spectroscopy, combined with a cluster sample with negligible relative distance errors, allows us to derive a Fundamental Plane with minimal systematic uncertainties. From the apertures we tested, we find that velocity dispersions measured within a circular aperture with radius equal to one effective radius minimizes the intrinsic scatter of the Fundamental Plane. Using simple yet powerful Jeans dynamical models, we determine dynamical masses for our galaxies. Replacing luminosity in the Fundamental Plane with dynamical mass, we demonstrate that the resulting Mass Plane has further reduced scatter, consistent with zero intrinsic scatter. Using these dynamical models, we also find evidence for a possibly non-linear relationship between dynamical mass-to-light ratio and velocity dispersion.2015MNRAS.451.2723Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/451/2723CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/147 : The SDSS Photometric Catalogue, Release 12 (Alam+, 2015)J/AJ/111/42 : Galaxies in Abell 168 (Tomita+ 1996)J/A+AS/128/67 : BVR photometry of Abell 85 (Slezak+ 1998)J/A+AS/129/281 : ABCG 85 velocities catalogue (Durret+ 1998)J/A+A/495/379 : Optical radial velocities in A85 (Bravo-Alfaro+, 2009)J/MNRAS/446/1567 : SAMI Galaxy Survey: EDR (Allen+, 2015)J/MNRAS/454/2050 : SAMI Pilot Survey (Fogarty+, 2015)J/MNRAS/456/1299 : SAMI Galaxy Survey: gas streaming (Cecil+, 2016)J/MNRAS/458/1590 : Deep spectroscopy of Abell 85 (Agulli+, 2016)J/ApJ/835/104 : SAMI Galaxy Survey: rotators classificationhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/451/2723https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/451/2723http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/451/2723https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/451/2723https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/451/2723http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/451/2723GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/451/2723/table1 (Properties of the three clusters from which our is drawn)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/451/2723/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/451/2723/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/451/2723/table1?GETtext/xml+votable180.050000true10.4075-9.34250.005555555555555556Cone search capability for table J/MNRAS/451/2723/tablea1 (Fundamental Plane (FP) parameters and other properties of the 106 galaxies in our sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/451/2723/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/451/2723/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/451/2723/tablea1?GETtext/xml+votable180.050000true9.7782192-8.79953720.0055555555555555566/17236-17237 17239 17920 18009 18011 18605 18607 18618 18949 18960https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/451/2723?format=asciiOpticaldefaultJ/MNRAS/451/2723/table1Properties of the three clusters from which our is drawnrecnoRecord number assigned by the VizieR team.
