	Figure 1: Distribution of water maser features in IRAS 19134+2131 observed with the VLA. An uncertainty of a maser feature position is indicated by the size of a cross. The blue-shifted (-122 km s-1  -117 km s-1) and red-shifted (-37 km s-1 -10 km s-1) maser features with respect to the source systemic velocity,  = -67 km s-1, are shown in filled and opened circles, respectively.

Figure 2: Distributions of water maser features in IRAS 19134+2131 observed with the VLBA. Upper: radial velocity distribution of the maser features on 4 January 2003. The blue-shifted (-122 km s-1  -117 km s-1) and red-shifted (-37 km s-1 -10 km s-1) maser features with respect to the source systemic velocity,  = -67 km s-1, are shown in filled and opened circles, respectively. Lower: sub panels zooming up the blue-shifted a) and red-shifted b) clusters of maser features. Opened and filled stars indicate the feature locations on 4 January and 7 March in 2003, respectively.

	Figure 3: Possible heliocentric distance, r, and Galactic rotation velocity, , of IRAS 19134+2131 located at (l, b)= (54 867, 4 642). Three slopes of the function corresponding to the proper motions, , -4.4, -4.2 mas yr-1, respectively, are plotted together with another curve corresponding to the source radial velocity  = -67 km s-1.
