英文摘要We report trigonometric parallax and proper motion measurements of 6.7 GHz CH3OH and 22 GHz H2O masers in eight high-mass star-forming regions (HMSFRs) based on Very Long Baseline Array (VLBA) observations as part of the Bar and Spiral Structure Legacy (BeSSeL) Survey. The distances of these HMSFRs combined with their Galactic coordinates, radial velocities, and proper motions, allow us to assign them to a segment of the Perseus arm with l less than or similar to 70 degrees. These HMSFRs are clustered in Galactic longitude from to neighboring a dearth of such sources between longitudes to approximate to 50 degrees to approximate to 90 degrees.
