I present here an OBSOLETE EARLY ATTEMPT at UML® Parsing Analysis of selected parts of my old 1988 honours thesis 'An analysis of image formation by MOST (Molonglo Observatory Synthesis radioTelescope)' into UML2 components, ports, and parts, using Composite Structure diagrams, to illustrate the basis of rotational aperture synthesis in the Molonglo Observatory Synthesis Telescope (MOST).
This work was performed in about 2005/2005 using the MD10EAPbeta2 early release version of MagicDraw® UML (aka Magic Software Architect), which offered a degree (only) of UML2 Port and part Property support in Composite Structure diagrams. (In 2007-2008 I worked together with the MagicDraw UML and SysML teams on greatly improving port-based engineering with MagicDraw 16.0.)
The MOST radio-synthesis provides and excellent test case for UML2.0 tools, and despite limitations of the older version of MagicDraw UML that I used, these diagrams remain of value to those interested in modelling instruments in UML.
The model is based on:
- Examination of my honours thesis from 1988, which also contains some figures of the MOST geometry, the skymap, and the fan-beam and synthesised beam.
- The classic description of the MOST synthesis by Mills:
Mills, B., The molonglo observatory synthesis telescope, Proc.ASA, 4, 156-159, 1981 - The classic description of rotational aperture synthesis by Perley:
Perley, R., Pencil beam formation by fan-beam rotation in radio astronomy, Astron.J., 84, Sep 1979 - Discussions with Dave Crawford, including this paper:
Crawford, D., The ideal molonglo observatory telescope, April 1988, Dept. of Astrophysics, Univ. of Sydney. - Explanations by Michael Large, Lawrence Cram, Tony Turtle, and Bruce McAdam
- A little guesswork, interpolation, and some memory wracking.
