Figure 1:
The total power (continuous lines) and recovered flux (dotted
lines) spectra of the SiO masers observed in IRC +10011. The
dashed line indicates the systemic velocity of the source
(
9.2 km s-1, taken from Cernicharo et al. 1997). |

Figure 2:
Integrated intensity maps for the SiO maser emissions in
IRC +10011. Top: 28SiO v=1 ( left) and v=2 ( right)
J= 1-0 rotational transitions. The peak flux is 9.14 and 9.72 Jy beam
 km s-1 respectively, the contour levels in both images are 0.28, 0.57, 1.14, 2.28 4.16 and 8.34 Jy beam
km s-1 and the rms noise level 0.07 Jy beam
km s-1. Bottom: 28SiO v=1 J= 2-1 ( left) and 29SiO v=0 J= 1-0 ( right) maser transitions. The peak flux is 3.37 and 1.77 Jy beam
km s-1 respectively. The contour levels are 0.15, 0.20, 0.40, 0.80, 1.60 and 3.20 Jy beam
km s-1 for the
J= 2-1 line, and 0.08, 0.12, 0.23, 0.46, 0.92 and 1.76 Jy beam
km s-1 for the J= 1-0 line. The rms noise levels in the maps are 0.02 and 0.01 Jy beam
km s-1 respectively. Circles denote the ring fitting of the masing regions (dashed: mean radius  ,
continuous:
and
defined as 
 ). We note that the four images have the same scale to ease the comparison between the emitting regions and that in all the cases the derived center of the ring is placed in the center of the box, while the origin of the map remains at the position of the reference spot (see Sect. 2). |
