- Star Atlas v-0.06b1
- Written by Youhei Morita using THINK C 4.0.
-
- This program draws a map of a region of the sky. Unlike the preceding
- application StarChart (*), it conforms to the Apple standard menu system
- with reverted black menu bar. (Otherwise you will find the white menu
- very disturbing...) It runs with MultiFinder. I confirmed it runs on MacPlus,
- SE, SE/30 and II with System 6.0.2 or later.
-
- To run this program, an accompanied data file "star.catalog" should be
- put in the same folder. This data file is converted from David Palmer's
- "stars.cart", which he claims as public domain and contains the position,
- magnitude, name and color of 1573 stars. To change the center position
- of the Atlas, use R.A. (Right Ascension) and Decl. (Declination) menus.
- You can also change the center position by clicking a portion of the Star
- Atlas window. Zoom menu changes the scale of the Atlas.
-
- Star names can be displayed on the screen by checking "Display star
- names brigher than..." option in the "Preference..." dialog box. They are
- shown as abbreviated composites of their Greek prefixes and the
- constellation names. For example, "alpCMA" is CMA alpha (Sirius, aka
- Dog Star), and "betORI" is ORI beta (Rigel, Orion).
-
- Window size may be changed by dragging the grow icon at the lower
- right corner of the Atlas window although the grow icon itself is not visible.
- You will notice a change in the shape of mouse cursor from cross to arrow
- when you are in the grow box. You can also move the window by dragging
- a pixel-width white line just below the menu bar. Clicking in the zoom box
- in the upper right corner of the Atlas window will put the window back to the
- original position.
-
- Drawing a map takes time on old machines like Plus or SE (typically 30
- sec for poloar maps, namely Decl. = +/-90í and +/-60í, 10 sec for
- other maps), so please be patient!
-
- I wrote this program as a first practice of using Macintosh Toolbox
- routines. It can be freely distributed as long as *you* don't make money
- out of it. Certain portion of the copyright of this software belongs to
- Symantec Corp. Future plan is to calculate and display the planets and
- comets at any given date and time. Please send your comments and
- suggestions (no support guaranteed though) to:
-
- morita@jpnkekvx (Bitnet)
- morita@fnal.fnal.gov (Internet)
-
- Enjoy!
