“…In our previous papers we traced in detail regularities in the H 2 O maser variations for several late-type stars: RR Aql (Berulis et al 1998), VX Sgr , RT Vir ), R Leo (Esipov et al 1999), W Hya ), U Ori (Rudnitskij et al 2000), and RS Vir (Lekht et al 2001). In this paper we now present a complete set of 113 H 2 O line spectra obtained in 1981.…”

“…In our calculation, the v = 1, J = 1−0 SiO maser is stronger than the v = 2, J = 1−0 SiO maser at epochs 1 and 6, and the opposite case is true at epochs 11 and 16. The ratio of the v = 1, J = 1−0 to the v = 2, J = 1−0 maser intensity was reported to be nearly unity (Schwartz et al 1979;Spencer et al 1981;Nakada et al 1993) for normal late-type stars. However, Kim et al (2010) reported that this ratio varies from one source to another.…”

“…Single dish observations of the radio SiO masers in IK Tau were reported by Spencer et al (1981). Bains et al (2003) report MERLIN interferometric observations of IK Tau in the H 2 O line at 22 GHz which indicate that the masers are distributed in an oblate spheroid inclined to the line of sight.…”
