Dear ShareWare Vendor/Sysop:

 This file contains my distribution policy and information on
 the shareware version of "The Earth Centered Universe (TM)",
 or ECU (TM), for MS-Windows (TM).

 ---------------------------------------------------------------------------

 ECU is protected under international copyright treaties and
 I (David Lane) retain all rights to this software.

 As a shareware distributor, you have permission to distribute
 my shareware in its original electronic form as long as you:

 * identify it as shareware (with an appropriate definition)

 * leave all intellectual property (copyright) notices in place

 * notify me, if you are publishing it in a catalog or CD-ROM

 * do not distribute the files "YBSC2.ECU", "SAC2.ECU", "SAO1.ECU",
   "SAO2.ECU", "PINDEX.ECU", or "PTERMS.ECU", should they
   inadvertantly become part of the shareware package that you have
   received

 ..and as long as I do not request that you stop.

 That's it.

 You may archive our programs, unarchive them, use your own installation
 routines, include them with other programs on the same diskette, and do
 essentially anything you want as long as you follow these simple rules.
 I want the widest possible distribution, and don't want to stand in
 your way so long as you are honest with our mutual customer.

 My normal distribution sequence is:

 1  New versions are offered to our registered users and are
    automatically shipped to new registrants.

 2  New versions are posted on CIS in the ASTROFORUM (Lib 7 as
    ECUSHA.EXE).  Use IBMFF on ID 71601,247.

 3  I send copies of major revisions of ECU to distributors who have
    notified me of their interest.  If you are a catalog house, send me
    a copy of the catalog in which the program appears and I
    will send you a copy of any major updates to my software.

 If you have any questions, concerns, or complaints, please contact me:

 International:  If you are a publisher interested in translating and
 supporting ECU in another language, please contact me to discuss an
 agreement for your language and country.  If you are interested in
 providing registration and support services outside of North America,
 I am interested in working with you.

 Short Description:

        ECU V1.4 is a Sky Visualization Program for Microsoft Windows 3.x
 called "The Earth Centered Universe".  It is capable of simulating
 many of the features of the Earth's sky.  You only need to
 enter your geographic location and the time and the local sky is
 simulated on the screen in a colourful display.  This includes, but
 is not  limited to the stars, planets, Sun, Moon, and "deep sky" objects.
 Constellation, coordinate grid, ecliptic, and local horizon lines are
 also displayed.  ECU is designed as an observing tool for the observing
 amateur astronomer, but is equally useful to the "armchair" astronomer
 or other interested person interested in the night sky.

 Long Description:

        ECU V1.4 is a Sky Visualization Program for Microsoft Windows 3.x
 called "The Earth Centered Universe".  It is capable of simulating
 many of the features of the Earth's sky.  This includes, but is not
 limited to the stars, planets, Sun, Moon, Comets, and "deep sky" objects.
 ECU is designed as an observing tool for the observing amateur
 astronomer, but is equally useful to the "armchair" astronomer or other
 interested person.

        ECU operates on a PC from within the Microsoft Windows 3.x
 environment.  Some of the features of ECU are listed below:

       - fast compared to many commercial packages - mostly integer math
         so math processor is not needed, but is supported to improve
         speed of solar system calculations, etc.
       - colourful display - colours of all screen elements controllable
         by user with scroll bars
       - high quality star charts can be printed on any Windows compatible
         printer or plotter
       - continuous display of LMT, UTC, latitude and longitude, RA/DEC,
         AZ/ALT, field size, and star mag limit
       - databases: Yale star catalogue to 6.5 magnitude
                    SAO star catalogue to 9.5 magnitude (optional)
                    SAC deep sky database (over 10,000 objects)
                    planets, Sun, Moon, and Comets
       - very easy to use - zoom box, center image, zoom in/out, etc. all
         done with the mouse.  Scroll bars for RA and DEC or Alt/Az.  Hot
         keys and buttons for common functions
       - click on an object and an information box pops up.  All objects
         give RA, Dec, azimulh, altitude, rise and set times, and magnitude.
         Planets/Sun/Moon give distance (AU or km), angular size (" or '),
         and phase (or age).  Comets give distance to the Sun and the Earth
         in AU.  Yale stars give Yale number, HD number, SAO number,
         Flamsteed/Bayer designation, Spectral type, and proper motion.  SAO
         stars give SAO number, and spectral type.  Deep sky object provide
         a varying amount of info but usually provide the name (an other name),
         Dreyer description, size, classification, etc.  The coordinates
         can be precessed to the current date/time.
       - the user can display a GIF picture of the object, if one exists.
         None are provided with ECU.  Some may become available at a small
         fee.
       - measure angular separation on the sky with the mouse
       - load and save all settings to named configuration files
       - undo last operation
       - time set as LMT, UTC, or system clock (daylight savings flag, too.)
       - time format as 24 hour or am/pm
       - observer's location entered by lat/long or pick list of preprogrammed
         cities (add your own, too)
       - control the effects of observer's parallax, nutation, precession, light travel
         time, aberration, and atmospheric refraction
       - show sky as white on black background or black on white background,
         or in full colour
       - also supported is a "red" mode to save your night vision if used in an
         observatory
       - set magnitude limits of deep sky and stars (with scroll bars)
       - select type of deep sky objects displayed (with check boxes)
       - displays horizon line, ecliptic line, ra/dec grid (fine and coarse),
         zenith marker, constellation lines, IAU constellation boundary lines,
         labels for bright stars, constellations, messiers, coordinate grid, etc.
       - center on - RA/DEC
                   - Azim/Alt
                   - bright stars
                   - constellations
                   - messiers
                   - points on horizon (north, south, etc.)
                   - solar system objects
                   - search the database and center on the object found
       - animation mode - time increments in steps from 1 minute to four years or a
                          user selected arbitrary increment
                        - set direction either forward or reverse
                        - lock to Sun, Moon, Planet, alt/az or ra/dec
                        - trails of objects supported
       - and much, much more!
       - system requirements:  286/386/486 100% PC compatible
                               386DX recommended
