Series of spectral index plots shown as a function of stellar effective temperature, merging the known Taurus Class II (filled circles) and Class III (crosses) members with; mid-IR emission (IRAC, MIPS and WISE), far-IR emission (PACS and MIPS), and 1.3 mm emission (for those targets not with no reported 1.3 mm observations, the nearest submm/mm observation was scaled to 1.3 mm assuming F_ν ∝ ν²). Symbols leftwards of the vertical dotted lines, plotted at T_eff = 2963 K and T_eff = 3270 K, indicate the substellar (≤M6.25) members and members of the TBOSS sample (≤M4), respectively. Blue squares enclose the targets identified in the literature with transition disks and green squares enclose the candidate transition disks objects identified within this paper.
