  • 摘要:Using the line ratio between the SiO (5–4) and the SiO (2–1) observed by Zhang et al. (2000) with a synthesized beam of 9. ?? 5×8. ?? 0, we derived the physical conditions of the gas in the high-velocity clumps. For our analysis we selected the portion of the high-velocity range that is less affected by the miss- ing flux. The analysis was performed at the B0i and B1a po- sitions, at which the SiO (5–4) emission was detected above the 5σ level. We note that an analysis using several SiO lines ob- served with a single-dish telescope has been made by Nisini et al. (2007). However, they used single-pointing observations, which means that the data were taken with different beam sizes, for instance ∼27 ?? for SiO (2–1) and ∼11 ?? for SiO (5–4). In addi- tion, the line ratios used the total integrated intensity, including the low-velocitycomponent,whereas we used higher-resolution data and focused on the high-velocity component.
