Notes. Additional 14 Scutum arm sources will be published in Li et al. (in prep.).

(a)

The proper motion values in the table correspond to the proper motion of the maser spot underlined in Figs. 1 and C.1, except for sources marked with a star for which the proper motion corresponds to the proper motion estimate of the central object (see Appendix D for more details).
