Break classification summary.
| Type 0: | Not exponential |
| Type I: | No significant disk break |
| Type IId: | Down-bending break at spirals, lenses, rings, etc. |
| Type IIa: | Down-bending break at asymmetric feature (e.g., tidal stream) |
| Type IIIa: | Up-bending break at asymmetric feature |
| Type IIId: | Up-bending break marking symmetric outer disklike features, e.g., spiral arms or HII regions |
| Type IIIs: | Up-bending break marking outer spheroidal component |
Notes. The nomenclature Type I, Type IIId, and Type IIIs are borrowed from previous studies, and are defined similarly (Freeman 1970; Pohlen & Trujillo 2006; Erwin et al. 2008). Type IIa breaks are akin to Type II-AB from Pohlen & Trujillo (2006), Erwin et al. (2008). Type IId breaks include all Type II break subtypes from Pohlen & Trujillo (2006), Erwin et al. (2008), Laine et al. (2014), L16 except those inside the bar radius.
