The author is a teacher of physics, especially astronomy. He works at the Nicholas Copernicus Observatory and Planetarium in Brno and teaches (see Astrofyzika) and Fyzikální pozorování) some hours a week students of the Didactics of Physics at the Faculty of Education of the Masaryk University in Brno and of Faculty of Creative Arts of the Technical University in Brno.
As a volunteer, he is a member of environmental organization Veronica (works in its Eco-counselling programme) and of the Society for Sustainable Living (leads its regional branch in Brno).
Both fields meet at the issue of light pollution. As a member of the International Dark-Sky Association, he recommends you to have a look at least at the Good Neighbor Outdoor Lighting brochure, or its Czech translation Dobré venkovní osvětlování.
The author offers four kinds of products (see ev. his ftp directory):
Package of Programmes
The bulk of package has been written by Jan Hollan and his colleagues. It includes many astronomical and general purpose programmes and the needed units. The astronomical part covers most of my needs as an astronomy teacher. Written in Borland Turbo Pascal language. Source codes, instruction booklet, example configuration and batch files, needed LaTeX input. Included are standard PStools (not written at Brno Observatory!) for handling PostScript files. Just download pas_jh.zip.
In executable form (*.exe, for MS-DOS etc.,), the programmes from the package are available exe_jh.zip ( for PCs without co-processor) or exe87_jh.zip (for PCs with mathematical co-processor), but they should be downloaded only together with the pas_jh.zip.
Moreover, if you do not have a Borland compiler, you should download Borland Graphic Interfaces BGI.zip - these are needed by several programmes running in graphic mode. This zip file is a part of Borland Turbo Pascal, that needs not to be purchased. Buy the whole Turbo Pascal to be able to modify and compile the programmes youself.
One of the programmes is offered separately as well, as it is perhaps
quite unique: the programme for constructing
