Description of source "G10.32-0.26" from Kang et al. (2016)

The linear polarization of G10.320.26 is detected only at 44 GHz (see Figure 5(b)). It is peculiar because the linear polarization is not detected in the brightest peak of the total ux prole at vLSR 32.5 km s1 (A component in Figure 9(a)) with an upper limit of 0.9%, but its secondary peak at vLSR 35 km s1 (B component in Figure 9(a)) shows polarization.

We conrmed this trend by observing them in two or more epochs. As mentioned in Section 2.1, our observations were targeted for the brightest features in the total intensity. If the weaker feature is largely displaced from the brightest one, for example, by 30, that could produce articial polarization of up to 2%. The displacement of the 35 km s1 component from the brightest peak is less than 2, according to the VLBI observation using the KVN and VERA combined array (KaVA; M. K. Kim et al. 2016, in preparation) and its observed degree of polarization is 4%9%, well above 2%. Thus, these detections are very likely real.
