Notes. Column 1 reports the name of the POETS targets: the two sources in italic characters have been observed prior of the POETS survey; Cols. 2 and 3 give the trigonometric parallax distance from BeSSeL (available for all but four sources, for which the kinematic distance is reported) and the evaluated bolometric luminosity, respectively: kinematic distances and more uncertain luminosities are given in italic characters, and values which might be severe upper limits are enclosed within brackets; Cols. 4 and 5 give the RA and Dec coordinates, respectively, of the YSO, pinpointed by JVLA, high-angular resolution, radio continuum observations; Cols. 6 and 7 list the number of detected maser cloudlets and the maximum maser separation from the YSO, respectively. (a) In a few cases where the continuum emission shows two nearby peaks, we choose the peak closer to most of the water masers. In three objects, G005.88−0.39, IRAS 20126+4104, and AFGL 5142, previously studied at subarcsecond resolution with millimeter and near-infrared interferometers, we have used the position of the YSO identified through continuum or molecular line emissions. (b) In this target, the water maser emission has faded away over the VLBI observing epochs, and nor trigonometric parallax distance neither reliable maser proper motions have been measured. (c) In this target, the water maser emission comes from two nearby YSOs, resolved through subarcsecond VLA observations, named VLA 3A and VLA 3B. (d)In this target, the water maser emission comes from two nearby YSOs, resolved through subarcsecond VLA observations, named VLA-1 and VLA-2.
