¹	ABLIKIM 2014D fit ${\mathit \sigma (}$ ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit \tau}^{+}}{{\mathit \tau}^{-}}{)}$ at different energies near threshold.

²	AUBERT 2009AK and BELOUS 2007 fit $\tau $ pseudomass spectrum in ${{\mathit \tau}}$ $\rightarrow$ ${{\mathit \pi}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}{{\mathit \nu}_{{\tau}}}$ decays. Result assumes ${\mathit m}_{{{\mathit \nu}_{{\tau}}}}$ = 0.

ABBIENDI 2000A fit ${{\mathit \tau}}$ pseudomass spectrum in ${{\mathit \tau}}$ $\rightarrow$ ${{\mathit \pi}^{\pm}}{}\leq{}2{{\mathit \pi}^{0}}{{\mathit \nu}_{{\tau}}}$ and ${{\mathit \tau}}$ $\rightarrow$ ${{\mathit \pi}^{\pm}}$ ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}{}\leq{}1{{\mathit \pi}^{0}}{{\mathit \nu}_{{\tau}}}$ decays. Result assumes ${\mathit m}_{{{\mathit \nu}_{{\tau}}}}$=0.

⁴	BAI 1996 fit $\sigma\mathrm {( {{\mathit e}^{+}} {{\mathit e}^{-}} \rightarrow {{\mathit \tau}^{+}} {{\mathit \tau}^{-}} )}$ at different energies near threshold.

⁵	ALBRECHT 1992M fit ${{\mathit \tau}}$ pseudomass spectrum in ${{\mathit \tau}^{-}}$ $\rightarrow$ 2 ${{\mathit \pi}^{-}}{{\mathit \pi}^{+}}{{\mathit \nu}_{{\tau}}}$ decays. Result assumes ${\mathit m}_{{{\mathit \nu}_{{\tau}}}}$=0.

⁶	BACINO 1978B value comes from ${{\mathit e}^{\pm}}{{\mathit X}^{\mp}}$ threshold. Published mass 1782 MeV increased by 1 MeV using the high precision ${{\mathit \psi}{(2S)}}$ mass measurement of ZHOLENTZ 1980 to eliminate the absolute SPEAR energy calibration uncertainty.

BALEST 1993 fit spectra of minimum kinematically allowed ${{\mathit \tau}}$ mass in events of the type ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit \tau}^{+}}{{\mathit \tau}^{-}}$ $\rightarrow$ (${{\mathit \pi}^{+}}{{\mathit n}}{{\mathit \pi}^{0}}{{\mathit \nu}_{{\tau}}}$ )(${{\mathit \pi}^{-}}{{\mathit m}}{{\mathit \pi}^{0}}{{\mathit \nu}_{{\tau}}}$ ) $\mathit n{}\leq{}$2, $\mathit m{}\leq{}$2, 1${}\leq{}\mathit n+\mathit m{}\leq{}$3. If ${\mathit m}_{{{\mathit \nu}_{{\tau}}}}{}\not=$0, result increases by (${{\mathit m}^{2}}_{{{\mathit \nu}_{{\tau}}}}$/1100 MeV).

⁸	BAI 1992 fit $\sigma\mathrm {( {{\mathit e}^{+}} {{\mathit e}^{-}} \rightarrow {{\mathit \tau}^{+}} {{\mathit \tau}^{-}} )}$ near threshold using ${{\mathit e}}{{\mathit \mu}}$ events.
