J/ApJ/429/253       W49N H2O masers (Gwinn, 1994)

Physical structure of H2O masers in W49N Gwinn C.R. <Astrophys. J. 429, 253 (1994)> =1994ApJ...429..253G (SIMBAD/NED BibCode)
ADC_Keywords: Masers ; Radio lines ; VLBI Keywords: masers ISM: molecules - ISM: jets and outflows - ISM: individual (W49) - ISM: kinematics and dynamics Description: VLBI observations of a H2O maser were done at five epochs in 1980-82 with a 5 station VLBI network (see 1992ApJ...393..149G). A model was fitted to each peak in any spectral channel exceeding 5 times the rms background. The minimum level of this background, due to system noise at the antennas, was about 0.2Jy at each epoch. The model parameters include right ascension and declination offset (x, y) relative to a reference position; the total flux density, S; and the angular diameter θH, of the best-fitting Gaussian distribution of intensity. The fitted parameters are in table1.
