Description

We report trigonometric parallaxes for the high-mass star-forming regions G35.20-0.74 and G35.20-1.74, corresponding to distances of 2.19+0.24-0.20 kpc and 3.27+0.56-0.42 kpc, respectively. The distances to both sources are close to their near kinematic distances and place them in the Carina-Sagittarius spiral arm. Combining the distances and proper motions with observed radial velocities gives the locations and full space motions of the star-forming regions. Assuming a standard model of the Galaxy, G35.20-0.74 and G35.20-1.74 have peculiar motions of ∼13 km s-1 and ∼16 km s-1 counter to Galactic rotation and ∼9 km s-1 toward the North Galactic Pole.
