- STAR 2000
- =============
-
- A freeware subset of Star Base from Debonair Software
-
- Version 1.11
-
- by J. Andrzej Wrotniak
-
-
- Star 2000 is a simplified version of Star Base. The latter is
- a commercial program, available from Debonair Software, while
- Star 2000 can be distributed freely as long as all the
- accompanying files (including this one) remain intact.
-
- This is a new, updated version of our program, based on Star
- Base 1.10. If you have used the previous release, you may want to
- skip most of this document and jump directly to the last point in
- the "Update History" section.
-
-
- WHAT DOES THIS PROGRAM DO?
-
- Star 2000 is a star database, browser and plotter, addressed
- to those with interest in astronomy. It contains data on 2000
- brightest stars from the Yale Bright Stars Catalogue and on 100
- brightest deep sky objects from the RNGC, allows for accessing the
- database in various modes, and for plotting sky maps in various
- reference frames, projections and magnifications.
-
- The program includes also Sun, Moon and the planets (but only
- for 00:00 GMT of any day, which really is a limitation only for
- Sun and Moon). The full implementation of planetary ephemerii is,
- of course, available in Star Base.
-
- Star 2000 uses the familiar GEM interface, is quite intuitive
- in use (at least we hope so), and has on-line help. Therefore we
- have decided not to include any detailed user instructions with it
- -- just a few pieces of the most vital information.
-
-
- HARDWARE REQUIREMENTS
-
- Star 2000 will run on any Atari ST (TOS in ROM), STe or TT
- with color or monochrome monitor (monochrome looks better!) and
- any disk drive. It will also run on a 1280*960 (monochrome)
- Moniterm display -- and the program looks goooood in this mode!
-
- We were unable to test Star 2000 in the new TT resolutions,
- but the program has been written with compatibility in mind, and
- we hope it works just fine. If you try Star 2000 in one of the new
- screen standards, please let us know the results!
-
- Computers with 512k of RAM may require that most of the
- desktop accessories and other memory-resident programs be removed.
- This new version has quite a many new, memory-hungry features.

-
- DISK FILES
-
- The following files are required for proper functioning of
- Star 2000, and should be placed in the same directory (root or
- folder):
-
- * STAR_2K.PRG - the program file,
-
- * STAR_2K.RSC - the resource (monochrome or color),
-
- * STAR_2K.HLP - the on-line help file (can be printed out),
-
- * STAR_2K.VM - the data file with stars,
-
- * STAR_2K.DSO - the data file with deep sky objects,
-
- * PLAN.PER - data for the planets.
-
- Really, only the .PRG and .RSC files are absolutely
- necessary, if any of the remaining files are missing (or renamed),
- just the corresponding features will be disabled.
-
-
- STAR BASE: WHAT YOU ARE MISSING
-
- Here is the list of differences between Star 2000 and
- Star Base (at least the current version):
-
- * Star Base contains data on all 9096 stars from the YBS
- Catalogue (up to apparent magnitudes of about 6.5), while
- Star 2000 is limited to the brightest 2000 stars.
-
- * Star Base uses data od 333 brightest deep sky objects (down
- to 9.0m) - not just 100 as in Star 2000.
-
- * Star Base can also use additional data sets. The first of
- those, the Big Sky, available from Debonair Software for a
- mere $22, contains data from the SAO Catalogue on more than
- 40000 stars (down to 8.0m) and 1300 deep sky objects.
-
- * Star Base allows for selective data input from disk: stars
- and deep sky objects can be cut off at a given magnitude
- value and/or limited to a given circular region of the sky.
- This on one hand speeds up most of the operations, and on the
- other -- allows for using the 1.3 Mb Big Sky data set on a
- 1Mb machine.
-
- * Star Base accepts a configuration file with observer
- location, time, GMT offset and data input limits. It will
- also allow to update the time from the computer's clock.
-
- * Star 2000 allows for plotting and co-ordinate display in the
- equatorial, ecliptic and galactic reference frames. The
- horizon frame is available only for 00:00 GMT (any date). In
- Star Base the horizon frame can be set to any date, time and
- location.
-
- * Similarly, the positions of Sun, Moon and the planets are
- limited in Star 2000 as above. Star Base is free of that
- limitation.
-
-
- Star 2000 Page 2 Version 1.11
-
-
-
- * The Solar System data in Star Base includes also comets
- (currently 14 of them, reaching the perihelium in 1992).
-
- * Mapping is limited in Star 2000 to map ranges between down to
- 60 degrees. Star Base moves this limit down to 4 degrees.
-
- * The spectrum and luminosity information (Harvard-Yerkes
- classification) in Star 2000 is limited to the simple
- spectral class and population (e.g. F8IV). Star Base provides
- the full data here (up to 24 characters).
-
- As you can see, there is just one really painful limitation
- in Star 2000 (in addition to more limited data set): the
- observation time, important for the skygazers. We have some
- feeling of guilt about it, but we had to use this dirty trick in
- order to sell some copies of the Star Base, which -- believe it or
- not -- took us some time and effort to develop. (The previous
- version was more limited here, freezing the date to January 1,
- 2000).
-
- You have to be warned: Star Base requires 1Mbyte of memory
- and a double-sided floppy drive, and the Big Sky runs much nicer
- with more (and a hard disk).
-
-
- HOW TO GET STAR BASE
-
- If, after trying out Star 2000, you decide to buy Star Base,
- send $43 (check or money order) to
-
- Debonair Software
- P.O.Box 521166
- Salt Lake City, UT 84152-1166
-
- The price includes shipping (Utah residents add 6% tax, and
- foreign orders please add $5 US extra). You will be also entitled
- to one update at no extra cost. A nice manual, of course, comes
- with the package.
-
-
- REMARKS, SUGGESTIONS, BUG REPORTS
-
- Whether you buy Star Base, or decide that Star 2000 is all
- you need at the moment, we would appreciate all remarks and
- enhancement suggestions you may have on either program. You can
- contact the program author on-line:
-
- CompuServe: 70611,2552
- GEnie: J.Wrotniak
-
- If you do not subscribe to these services, just write us at
- our Utah address shown above. We read all letters and even answer
- them. More important, we take them into account during the program
- enhancement process.
-
- We are not aware of any bugs in Star 2000 (although we are
- sure there must be some!). If you notice or suspect any
- misbehavior, please let us know, enclosing as many relevant
- details as possible. This will be most helpful in making the
- program robust and clean. Thanks.

- UPDATE HISTORY
-
- Version 1.0: Original, released for the Current Notes Library in
- July, 1990.
-
- Version 1.02: Sun, Moon and the planets added; some other
- improvements. Released in October, 1990.
-
- Version 1.05: Somewhat speeded up and reduced in size. A minor
- bug fixed. December 1990.
-
- Version 1.11: Deep sky objects (mapping and browsing) have been
- added. The Solar System ephemeris routines have
- been completely rewritten (with uniform use of
- J2000 co-ordinates). Two new map projections. Map
- range used instead of magnification. Changes in the
- user interface (including different menus).
-
-
- SALES PITCH: ABOUT SUB_CAL AND EL_CAL
-
- If you are into astronomy, the chances are that you may also
- have some need for math (numerical methods, statistics, linear
- algebra and such). We are very proud of our El_Cal: the Elementary
- Calculator (also known as the Math Machine). As elementary as it
- is, it faces no competition on the Atari ST, and not much on any
- other machine. (We know of two people who bought ST computers just
- to use this program!)
-
- El_Cal is now available in two versions (differing in just
- one feature, at least as of this writing), both significantly
- enhanced and improved since the original release almost three
- years ago:
-
- * Version 1.40 (with the most visible enhancement since the
- last year being the addition of unit conversion and physical
- constants). It still costs just $44 and is available in
- limited supply. (Foreign orders please add $5.)
-
- * Version 2.0. You will need this one if you need to solve
- systems of ordinary differential equations (up to 10), with
- or without solution plotting. This version requires 1 Mbyte
- of memory and sells for $63 (foreign extra $5, again).
-
- In the (highly improbable) case you do not know El_Cal, we
- encourage you to get a freeware subset of it, called Sub_Cal. It
- is available in the Current Notes Library, also on GEnie and
- CompuServe. Sub_Cal has been updated to Version 2.0, much more
- powerful than the Version 1.30 from November 1990. The freeware
- version does almost everything El_Cal does, but on a smaller scale
- (fewer equations, smaller matrices, lower degrees etc.). There is
- a very good chance you will like it.
