The term "astronaut" derives from the Greek words meaning "space sailor," and refers to all who have been launched as crew members aboard NASA spacecraft bound for orbit and beyond. Since the inception of NASA's human space flight program, we have also maintained the term "astronaut" as the title for those selected to join the NASA corps of astronauts who make "space sailing" their career profession. ...

We can see that the simulated UV color­transformation based on this new CCF can represent the observations. ...

... Hopkins: The Phoenix Deep Survey at 1.4 GHz . ... For details of the Phoenix multiwavelength deep survey, refer to MNRAS 296, p839, 1998. ... We present the first results from the Phoenix Deep Survey, a multiwavelength survey of a 2 deg diameter region. Observations in the radio continuum at 1.4 GHz carried out with the Australia Telescope Compact Array are described. The catalogue of over 1000 radio sources compiled from these observations is analysed, and the source counts are presented. ...

... A reconstruction method of 3D vector velocity field (three components of velocities) of gas in disks of spiral galaxies from observed line-of-sight velocity field is proposed. This method is based on Fourier analysis of observed velocity field. ... The knowledge of velocity field in spiral galaxies allows to clarify the nature of the galactic structures and mechanisms of their formation. ...

... Up: Science Software Applications . ... It has extensions for creating GUI (Tk) and object-oriented ([incr tcl]) applications. Several Tcl-based tools that may be used for astronomical and other scientific applications have been created and are discussed. One example is ptcl , which registers PGPLOT functions as Tcl commands, creating a powerful interactive plotting package. ... Both programs use the same C code, Tcl commands, and [incr tcl] classes; only the GUIs are different. ...
