array are compiled in a database known as the SMA
Calibrator List2 [5]. Essentially a collection of bright
objects (stronger than 750 mJy at 230 GHz and 1 Jy
at 345 GHz), these sources are monitored regularly,
both during science observations and dedicated ob-
serving tracks.
To select our sample, we identiﬁed objects in the
calibrator list that were also classiﬁed as BL Lacs or
FSRQs by the Candidate Gamma-Ray Blazar Sur-
vey [6, CGRaBS]. Of the 243 total objects in the
calibrator list, 171 (35 BL Lacs and 136 FSRQs)
have positive blazar class identiﬁcations, although
there are three sources (J0238+166, J0428-379, and
