... All the parameters provided in this database have been obtained using the the MIRIAD ( Sault et al. 1995 ) task MBSPECT . MBSPECT makes a spectrum of the velocity (or frequency) axis of a cube. The spectrum is beam-weighted, over the width specified, for the other image axes. ... Robust parameters are calculated by using an algorithm which minimises the mean absolute deviation of the flux-weighted velocities. mask= This specifies the x-axis ranges to be excluded from any continuum fit. ...

If value is omitted or is 0, -0, null, false, NaN , undefined, or the empty string ( "" ), the object has an initial value of false. All other values, including any object or the string "false" , create an object with an initial value of true. ... For Boolean objects and values, the built-in toString method returns the string "true" or "false" depending on the value of the boolean object. ...

... The search for distant objects which can be both galaxies and quasars is one of the most important problems of observational astrphysics, because it allows one to determine cosmological parameters connected with the time of appearence and evolution of stellar systems, large scale structure of the Universe. ... Radio galaxies are important objects to be studied because they are sources of infrared-optical-ultraviolet continuum, emission lines and continual radio emission. ...

Comment on J0627-3529 . We have detected the core of an FR-I object and early-type galaxy (Venturi et al. 1995). The core is 0.54 Jy at 2.3 GHz on the Parkes-Tidbinbilla baseline (Morganti et al. 1997) and 0.6 Jy at 5 GHz (VLA data, Ekers et al. (1989) and Morganti, Killeen & Tadhunter (1993)). The VLBA image at 2.3 GHz with the resolution of 15x9 mas shows a "core-jet" structure, with the core brightness of 494 mJy/beam (Venturi et al. ...
