* Although this source did not pass our chi-squared test, it displays much larger m and $\chi_{r}^2$ than the remaining secondary calibrators, suggesting a higher variability.

Note: Y computation was only performed for 0716+714 at 86 GHz, the only case for which the variability chi-squared test was passed.
