| Abstract: |
We present Very Large Array (VLA) observations of 43 GHz SiO (J = 1 → 0, v = 2 and v = 1) maser emission in a sub-sample of late-type stars in the Inner Galaxy selected on their relatively strong (> 0.5 Jy) 86 GHz SiO masers, and located within 2.5° of the galactic center. Furthermore we combine these results with a summary of previous surveys for 43 GHz SiO masers in the galactic center and comment on their use as calibrators for the Japanese "VLBI Exploration of Radio Astrometry" (VERA) network, which is intended to perform sub-milliarcsecond astrometry in the Galaxy and the galactic center. |
