Description of source "18416-0420" from Slysh et al. (1999)

This maser was first detected by Schutte et al. (1993). There is a single asymmetric line peaked at about 81.5 km s1 in both spectra. The shape of the shoul-der toward larger radial velocities looks different, but the difference can be caused by rather high noise in Schutte's et al. spectrum.
