Distribution of 86 GHz to 15 GHz fractional linear polarization ratio for sources with detected linear polarization in both our survey and MOJAVE. Six sources in the range 10 <m_{L, 86}/m_{L, 15}< 19 are not shown. The 15 GHz linear polarization fraction was computed from measurements of integrated total flux density and linearly polarized flux density from 15 GHz VLBI images taken by the MOJAVE team on the closest available dates to our 86 GHz observations.
