... The crucial problem that limits our knowledge of our own galaxy, and prevents us from working out how and when it formed, is our inability to measure direct distances to distant stars, and to determine their proper motions. If we could get accurate parallaxes and proper motions for every star in the galaxy, we'd have things completely wrapped up, and surely we'd be able to figure out galaxy formation. ... Luckily, this is just what should be achievable using space interferometers. ...

It is passed to Apache through the ZINET XPARM field since ZINET is the only way to start the server on TPF. A third group of options apply to both the informational displays (ZFILE) and running the server (ZINET XPARM): -d, -D and -f. The rest of Apache's options are either not applicable or are not supported on TPF. ...

... Fractals and multifractals are used to model hierarchical, inhomogeneous structures in several areas of astrophysics, notably the distribution of matter at various scales in the universe. ... It is pointed out that some of the difficulties regarding the convergence rates of algorithms used to determine scaling exponents for a fractal or multifractal, are intrinsically related to its texture, in particular, to its lacunarity . ...
