Abstract (from CDS):

We present a catalog of the 22GHz H2O maser profiles of the semiregular variable RT Vir. The observations were made from 1985 to 1996 at the RT-22 radio telescope of the Radio Astronomical Station at Pushchino, Russia.
Result. obtained after the analysis of the integrated fluxes, the average spectra, the centroid velocity and the superposition of the spectra are reported. Anticorrelation of the integrated fluxes of two spectral intervals (VLSR<15.5 and VLSR>21km/s) was found. The characteristic time variation of the maser emission at each of these groups was about 5-6 years. This phenomenon may be explained by a variation of the outflow of the matter from the star. The outflow is weakly bipolar. We can suppose that in such a model the enhancement of the outflow occured alternately with a period of about 5-6 years. The anticorrelation of the integrated fluxes of two groups of maser features, located symmetrically relative to the star, may be a result of this alternation.
