Distance PDF for G136.84+01.12, a 6.7 GHz methanol maser at ﹩v=-45﹩ km s−1 from the Pestalozzi et al. (2005) catalog. The (l, b, v)src values associate it with the Perseus spiral arm centered near 2.4 kpc (red dashed line). This information, coupled with association with the parallax source G133.95+01.05 (blue dotted line), favors the distance estimate of 1.96 ± 0.04 kpc over the arm center. Note that the kinematic distance (green dotted–dashed line) suggests a much greater distance of 3.7 kpc, as it does for many sources in this part of the Perseus arm which is known to be kinematically anomalous.
