Mean polarization fraction of Sgr A*. The error bars plotted are those of Table 2. Previous 86 and 112 GHz nondetections are marked with arrows. The error bars in the Aitken et al. (2001) measurements, marked with triangles, reflect uncertainty in the contribution from dust emission rather than variability associated with the source.
