Trigonometric Parallaxes of Massive Star-forming Regions. VIII. G12.89+0.49, G15.03?0.68 (M17), and G27.36?0.16
We report trigonometric parallaxes for three massive star-forming regions, corresponding to distances of 2.34(-0.11)(+0.13) kpc for G12.89+0.49 (also known as IRAS 18089-1732), 1.98(-0.12)(+0.14) kpc for G15.03-0.68 (in the M17 region), and 8.0(-2.0)(+4.0) kpc for G27.36-0.16. Both G12.89+0.49 and G15.03-0.68 are located in the Carina-Sagittarius spiral arm.
