cds-question@unistra.frgalaxiesphotometrygalaxy-classification-systemsRadial surface brightness profiles of spiral galaxies are classified into three types: (I) single exponential, or the light falls off with one exponential to a break before falling off (II) more steeply, or (III) less steeply. Profile breaks are also found in dwarf disks, but some dwarf Type IIs are flat or increasing out to a break before falling off. Here we re-examine the stellar disk profiles of 141 dwarfs: 96 dwarf irregulars (dIms), 26 Blue Compact Dwarfs (BCDs), and 19 Magellanic-type spirals (Sms). We fit single, double, or even triple exponential profiles in up to 11 passbands: GALEX FUV and NUV, ground-based UBVJHK and H{alpha}, and Spitzer 3.6 and 4.5{mu}m. We find that more luminous galaxies have brighter centers, larger inner and outer scale lengths, and breaks at larger radii; dwarf trends with M_B_extend to spirals. However, the V-band break surface brightness is independent of break type, M_B_, and Hubble type. Dwarf Type II and III profiles fall off similarly beyond the breaks but have different interiors and IIs break ~twice as far as IIIs. Outer Type II and III scale lengths may have weak trends with wavelength, but pure Type II inner scale lengths clearly decrease from the FUV to visible bands whereas Type III inner scale lengths increase with redder bands. This suggests the influence of different star formation histories on profile type, but nonetheless the break location is approximately the same in all passbands. Dwarfs continue trends between profile and Hubble types such that later-type galaxies have more Type II but fewer Type I and III profiles than early-type spirals. BCDs and Sms are over-represented as Types III and II, respectively, compared to dIms.2013AJ....146..104Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/146/104CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/144/134 : LITTLE THINGS survey of nearby dwarf galaxies (Hunter+, 2012)J/AJ/136/2563 : HI Nearby Galaxy Survey, THINGS (Walter+, 2008)J/ApJS/162/49 : UBV imaging of irregular galaxies (Hunter+, 2006)J/ApJ/647/1056 : ARAUCARIA project : NGC 6822 Cepheid variables (Gieren+, 2006)J/AJ/128/2170 : H{alpha} imaging of irregular galaxies (Hunter+, 2004)J/AJ/127/2031 : Catalog of neighboring galaxies (Karachentsev+, 2004)J/A+A/398/479 : Local galaxy flows within 5 Mpc (Karachentsev+, 2003)J/AJ/125/1261 : VI photometry of Sextans A Cepheids (Dolphin+, 2003)J/AJ/123/3154 : RV light curves of variable stars in Leo A (Dolphin+, 2002)J/A+AS/128/459 : BV photometry of irregular galaxies (Makarova+ 1998)J/AJ/116/146 : UGC 6456 HST photometry (Lynds+ 1998)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/146/104https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/146/104http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/146/104https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/146/104https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/146/104http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/146/104GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/146/104/table1 (Galaxy sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/146/104/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/146/104/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/146/104/table1?GETtext/xml+votable180.050000true158.8462917-1.61908330.0055555555555555566/38 580 816 933 955 2377 2382 2866 3042 3389 3550 3567 3573 4126 4313 4522 4537 4554 4689 4691 4811 5168 5203 5241 5263 5283 5287 5607 5635 5636 5638 5978 6046 6072 6399 6419 6502 6560 6623 7022 7445 7523 7687 7769 7799 7878 7926 7956 7970 7984 8028 8425 8519 8548 8557 8908 9102 9855 9954 10344 10348 10380 10627 10689 10762 10767 10810 10881 10910 10970 10976 11019 11041 11045 11092 11120 11140 11143 11933 11965 12570 13326 13516 13668 16016 16845 17165 17777 17912 18041 18649 18676 19580 19656 19833 19851 19990 20271 20296 20400 22495 22949 23514 24111 25575 25705 25756 26302 26323 26411 26456 26518 26858 26871 27062 27351 27568 27604 27857 27911 27926 27948 28025 28100 28149 28510 28523 28610 28631 28636 28659 28666 29699 29718 33986 34050 36276 38846 41987 48942https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/146/104?format=asciiOpticaldefaultJ/AJ/146/104/table4Fit parametersrecnoRecord number assigned by the VizieR team.
