Modeled three-dimensional distribution of OH/IR stars in the Galactic Disk

For deriving a kinematic distance, we used a python library provided by Trey Wenger (https://github.com/tvwenger/kd). This research has made use of: NASA’s Astrophysics Data System Abstract Service; NASA/IPAC Infrared Science Archive, which is funded by the National Aeronautics and Space Administration and operated by the California Institute of Technology; and Database of Circumstellar Masers. HI was supported by the Bilateral Collaboration Program by the Japan Society for Promotion of Science (JSPS) and KAKENHI programs 25610043 and 16H02167 by the Ministry of Education, Culture, Sports, Science and Technology (MEXT). JFG and HI were supported by the Invitation Program for Foreign Researcher by JSPS (S14128), by Amanogawa Galaxy Astronomy Research Center (AGARC), and the State Agency for Research of the Spanish MCIU through the ’Center of Excellence Severo Ochoa’ award for the Instituto de Astrofisica de Andalucia (SEV-2017-0709). JFG also acknowledges support by MCIU-AEI (Spain) grant AYA2017-84390-C2-R (co-funded by FEDER). JRD acknowledges the support of an Australian Research Council (ARC) DECRA Fellowship (project number DE170101086). H-HQ is partially supported by the Special Funding for Advanced Users, budgeted and administrated by Center for Astronomical Mega-Science, Chinese Academy of Sciences (CAMS-CAS), CAS ‘Light of West China’ Program and the National Natural Science Foundation of China (Grant No. 11903038).
