Proper Motions of Water Masers in W49 N Measured by KaVA

We report the proper motions of 22 GHz water masers toward W49 N that were observed by the KVN and VERA Array (KaVA) during 2017 February–May. We found 263, 268, and 310 features in three successive epochs; they were distributed in a region of size 4 × 4 arcsec ^2 . The strongest flux density was in...
