A CGPS Look at the Spiral Structure of the Outer Milky Way I: Distances
  and Velocities to Star Forming Regions
  We present a new catalogue of spectrophotometric distances and line-of-sight
systemic velocities to 103 HII regions between 90$^{\circ}\leq \ell
\leq~$195$^{\circ}$ (longitude quadrants II and part of III). Two new
velocities for each region are independently measured using 1-arcminute
resolution 21~cm HI and 2.6~mm $^{12}$CO line maps (from the Canadian Galactic
Plane Survey and FCRAO Outer Galaxy Surveys) that show where gaseous shells are
observed around the periphery of the ionized gas. Known and neighbouring
OB-type stars with published UBV photometry and MK classifications are overlaid
onto 21~cm continuum maps, and those stars observed within the boundary of the
HII emission (and whose distance is not more than 3 times the standard
deviation of the others) are used to calculate new mean stellar distances to
each of the 103 nebulae. Using this approach of excluding distance outliers
from the mean distance to a group of many stars in each HII region lessens the
impact of anomalous reddening for certain individuals. Final mean distances of
9 common objects with VLBI parallax distances show a 1:1 correspondence.
Further, comparison with previous catalogues of HII regions in these quadrants
shows a 50% reduction in scatter for the distance to Perseus spiral arm objects
in the same region, and a reduction by $\sim$1/$\sqrt{2}$ in scatter around a
common angular velocity relative to the Sun
$\Omega-\Omega_0$(km~s$^{-1}$~kpc$^{-1}$). The purpose of the catalogue is to
provide a foundation for more detailed large-scale Galactic spiral structure
and dynamics (rotation curve, density wave streaming) studies in the
2$^{\textrm{nd}}$ and 3$^{\textrm{rd}}$ quadrants, which from the Sun's
location is the most favourably viewed section of the Galaxy.
