cds-question@unistra.frgalaxiesspectroscopyradial-velocityvisible-astronomyinfrared-astronomyWe conduct spectral observations of 138 superthin galaxies (STGs) with high radial-to-vertical stellar disk scale ratios with the Dual Imaging Spectrograph on the 3.5m telescope at the Apache Point Observatory (APO) to obtain the ionized gas rotation curves with R~5000 resolution. We also performed near-infrared (NIR) H and Ks photometry for 18 galaxies with the NICFPS camera on the 3.5m telescope. The spectra, the NIR photometry, and published optical and NIR photometry are used for modeling that utilizes the thickness of the stellar disk and rotation curves simultaneously. The projection and dust extinction effects are taken into account. We evaluate eight models that differ in their free parameters and constraints. As a result, we estimated the masses and scale lengths of the galactic dark halos. We find systematic differences between the properties of our red and blue STGs. The blue STGs have a large fraction of dynamically underevolved galaxies whose vertical velocity dispersion is low in both gas and stellar disks. The dark halo-to-disk scale ratio is shorter in the red STGs than in the blue ones, but in a majority of all STGs, this ratio is under 2. The optical color (r-i) of the STGs correlates with their rotation curve maximum, vertical velocity dispersion in stellar disks, and mass of the dark halo. We conclude that there is a threshold central surface density of 50M_{sun}_/pc^2^ below which we do not observe very thin, rotationally supported galactic disks.2021ApJ...914..104Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/914/104CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/162 : Flat Galaxy Catalogue (Karachentsev+ 1993)VII/219 : Revised Flat Galaxy Catalogue (RFGC) (Karachentsev+, 1999)VIII/77 : HI spectral properties of galaxies (Springob+, 2005)V/147 : The SDSS Photometric Catalogue, Release 12 (Alam+, 2015)J/AJ/114/2402 : Rotation curves of early-type galaxies (Courteau+, 1997)J/AJ/114/122 : Spectroscopy of edge-on spirals (Giovanelli+ 1997)J/A+A/389/795 : Vertical structure of edge-on galaxies (Bizyaev+, 2002)J/A+A/445/765 : A Catalog of Edge-on Disk Galaxies (Kautsch+, 2006)J/MNRAS/373/781 : JHK photometry of faint standard stars (Leggett+, 2006)J/ApJ/688/237 : Disk corrugations in IC 2233 (Matthews+, 2008)J/ApJ/702/1567 : Structure of 2MASS edge-on galaxies (Bizyaev+, 2009)J/AJ/138/1938 : EDD: All Digital HI profile catalog (Courtois+, 2009)J/MNRAS/425/2741 : Parameters of Spiral galaxies from SDSS 7 (Hall+, 2012)J/ApJ/787/24 : Structural param. of true edge-on galaxies (Bizyaev+, 2014)J/ApJS/219/4 : S4G pipeline 4: multi-component decompositions (Salo+, 2015)J/MNRAS/465/3784 : Very thin discs galaxies properties (Bizyaev+, 2017)J/ApJ/861/49 : ALFALFA extragalactic HI source catalog (Haynes+, 2018)http://users.apo.nmsu.edu/~dmbiz/EGIS/ : Edge-on Galaxies In SDSS online cat.https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/914/104https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/914/104http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/914/104https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/914/104https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/914/104http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/914/104GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/914/104/stgs (Spectral observations (Table 1), structural parameters (Table 4) and parameters obtained in Model 6 (Table 6; see model definitions in Section 4.2) for the superthin galaxies (STGs))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/914/104/stgs?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/914/104/stgs?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/914/104/stgs?GETtext/xml+votable180.050000true105.82513.4640.0055555555555555566/20 45 50 337 388 647 689 722 971 1010 2171 2254 2681 2888 2895 4129 4439 4460 4575 4664 4697 4743 4769 5004 5098 5115 5400 5555 5592 5735 6089 6119 6221 6228 6253 6596 6604 7295 7302 8229 8303 8551 8646 9003 9127 9146 9224 9238 9358 9426 9440 9613 9760 9830 9834 9877 9898 10003 10075 10224 10236 10592 10635 10814 10999 11100 11235 11328 11388 11432 12633 13380 16725 16892 17232 17239 17387 17560 17652 17658 17862 17903 17912 18003 18007 18027 18035 18067 18083 18830 18956 19031 19077 19334 19568 19601 19778 19802 19947 19953 19963 20008 21871 22462 23212 23272 24154 26080 26333 26547 26903 26960 27016 27084 27206 27277 27508 27564 27581 27746 27800 27885 27889 27909 27980 27990 28082 28091 28320 28332 31630 31669 31673 36759 49078https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/914/104?format=asciiOpticalInfrareddefaultJ/ApJ/914/104/stgsSpectral observations (Table 1), structural parameters (Table 4) and parameters obtained in Model 6 (Table 6; see model definitions in Section 4.2) for the superthin galaxies (STGs)SimbadNameSimbad column added by the CDSmeta.idcharnullablerecnoRecord number assigned by the VizieR team.
