Distances to molecular clouds in the second Galactic quadrant
  We present distances to 76 medium-sized molecular clouds and an extra
large-scale one in the second Galactic quadrant ($104.75^\circ <l<150.25^\circ
$ and $|b|<5.25^\circ$), 73 of which are accurately measured for the first
time. Molecular cloud samples are drawn from $l$-$b$-$V$ space ($-95 < V_{\rm
LSR}< 25$ \kms) with the density-based spatial clustering of applications with
noise (DBSCAN) algorithm, and distances are measured with the
background-eliminated extinction-parallax (BEEP) method using extinctions and
Gaia DR2 parallaxes. The range of measured distances to 76 molecular clouds is
from 211 to 2631 pc, and the extra large-scale molecular cloud appears to be a
coherent structure at about 1 kpc, across about 40\deg\ ($\sim$700 pc) in the
Galactic longitude.
