INTRODUCTION
============  
For several years already PROCYON is the most extensive Astronomy program for the Series 3a/3c. 
With the release of the Series 5, many requests came to port the program for the new Psion 
machine. Here we release the first version of the program for the Series 5 and call it PROCYON X.  

PROCYON X: THE NEXT GENERATION
==============================
With this version we start a new generation of PROCYON X  that takes full 
advantage of the Psion 5 properties leading to the following features.
Identification of objects by pointing
Much higher precision
No more memories constraints, so more astronomical gizzmo's have been included
Faster rebuild of the sky 

For further news on the development of the program consult our homepages:

http://members.home.nl/psion/procyonx.html
http://www.sussenbach.myweb.nl

The Light version of PROCYON X is freeware, but the Pro version with many 
extras is shareware and can be obtained by registration (see Registration).

PROCYON X 
=========
When we take a long look at the sky on a clear, starry night, have you not 
been awed by the vastness and the beauty ? The distant star and galaxies 
appear to be fixed and unchanging, but actually you are observing a small 
portion of a dynamic and revolving universe.
PROCYON X is a Universe in the Palm of your Hands...  It is the most 
extended Astronomy software for the Psion Series 3a/c and 5. This small 
program is packed full of information including the Yale Star Catalogue, 
all Messier objects and the NGC Catalogue, Graphs and Tables, and much, 
much more!
Light and Pro PROCYON X is available as a Light version (freeware) and 
a Pro version (shareware).
Compared to the Light version the PROCON X Pro version has a number of 
extra features:

The Yale Star database is extended from magnitude 4.0 (Light) to magnitude 5.0 (Pro) (1600+ items);
The completel NGC Catalogue of Deep Sky objects (7800+ items) is available;
The Reference-star Database with stars to magnitude 6 is available in Zoom-window;
More than 750 Minor Planets and Comets;
Pictures of all 110 Messier Objects;
Constellation names in Main-view;
Jovian Red Spot visibility option;
Constellation Identification;
Constellation Names in Normal and Zenith View;
Lunar Eclipse Graph.

After registration you will receive a file named 5PROCYON.KEY. In addition 
you'll need the Procyon Auxiliary-pack (from http://members.home.nl/psion/procyonx.html). 
Installation of both files upgrades the Light version to the Pro version. Without these 
the current program will work as a Light version.

INSTALLATION
============ 
All files should be placed in a subdirectory named \SYSTEM\APPS\PROCYON. 
Procyon will search for these files on the Internal Disc C: and then on 
the D: disk. PROCYON.INI will be used to store your personal Preferences. 
If you have registered Procyon, you have received a file 5PROCYON.KEY 
which should also be placed in the above mentioned subdirectory.Finally, 
RMRAlarm.opx should be placed in a \SYSTEM\OPX directory

UPDATING FROM PREVIOUS VERSIONS

Since any new version contains new options you'll have to delete 
PROCYON.INI file and restart the program.
PROCYON X will prepare a new INI file when the program is closed.
Further you must put RMRAlarm.opx in a \SYSTEM\OPX directory

VERY IMPORTANT

Note that PROCYON X uses the English/American decimal separator, viz. a dot.
If you use a continental version of Series 5 with the comma as decimal 
separator you have to change that into a dot!

Start the program!

After proper installation the PROCYON X icon is shown in the Extra's bar. 
Press and the show starts. 
If you want to make a screen dump of a specific scene, 
ress Shift-Ctrl-Fn-S and give the file a name. The file is now saved 
in the root of the C: disk. Now start Sketch and choose File, More, Merge 
in and choose EPOC Picture as the file type. Having done this the file 
can be saved as a Sketch file. Now you can drag the file using Psiwin 
to your computer and it will automatically be converted to a bitmap 
file that can for instanc be used with your Word processor.

Angle of elevation in degrees of a star above the horizon, ranging from 
0 degrees at the horizon to 90 degrees in the Zenith.

The minor planets, most of which move around the Sun between the orbits 
of Mars and Jupiter. Several thousands of asteroids are known; the largest 
is Ceres.

Astronomical Unit (AU):
Mean distance between the Earth and the Sun. It is equal to 149,597,900 Km.

Azimuth:
Angle of a celestial object measured from the south point of the horizon 
westward to the meridian. Because of the earth's rotation, the azimuth 
of a body is changing all the time.

Cluster:
A collection of stars which are often associated.

Comet:
A member of the Solar System, moving around the Sun in an orbit which is 
generally highly eccentric.

Declination:
The angle measured in degrees perpendicular to the plane of the equator, 
ranging from -90 to +90 degrees.

Ecliptic:
A circle representing the apparent path of the Sun along the sky. Most 
planets move close to this plane.

Ephemeris:
A table giving the predicted positions of a moving celestial body, such 
as a planet or comet. PROCYON X gives the coordinates for the epoch and 
equinox 2000.0

A compilation of Nebulae and Clusters created by the 18th-century French 
astronomer Messier.

Meteor:
A small particle which after entering the Earth's atmosphere burns up 
leaving a trail of light. The streak of luminosity is known as a 
Shooting Star.

Phase:
The apparent changes in shape of the Moon and planets depending from

angle from Earth.

Planet:
A non-luminous body moving around a star. There are nine known major 
planets in our Solar System.

Planetary nebula:
A faint often circular nebula surrounding a star. They visually resemble 
a planet.

Radiant:
Point on the celestial sphere from which meteor of a given shower appear 
to radiate.

Right Ascension:
The angle measured eastward in hours along the equator between the meridian 
of an object and the meridian from a specific point in the constellation 
Pisces (vernal equinox). Ranging from 0 to 24 hours.

Vernal Equinox:
Point in the constellation Pisces that is reached by the Sun around March 21 and marks the beginning of the spring.

REGISTRATION
============
You may currently be using the Light Version of PROCYON X. This version is 
free for non-commercial use, but we would appreciate if you could send us a
postcard saying whether you like this program or not. Also suggestions for 
extensions of the program are welcome. 
If you really like this program or use it regulary you might consider 
registering for: Hfl 60, DM 60,- US$ 30 or UK  20.

Regsoft			US$ 30	www.RegSoft.com			4584
Regnet			US$ 35	www.swregnet.com/1703p.htm	1703

With the key-file system there is no need to re-install the program, which can be a lengthy process considering the size of the complete Pro version. Just add the '5PROCYON.KEY' file to \SYSTEM\APPS\PROCYON

TECH INFO
=========
The following files are absolutely required to run Procyon:

PROCYON.APP (Main Program).
5YALE.DBF (Yale Bright Star Catalogue).
5MESSIER.DBF (Messier Nebula).
5PROCYON.MBM
RMRAlarm.opx in a \SYSTEM\OPX directory

The following files are all optional:

5BINARY.DBF (Binary Stars Database);
5VARIABLE.DBF (Variable Stars Database);
EVENT.DBF (Event Base);
5MPLAN.DBF (Asteroids en Comets);
5MILKWAY.DBF (Milkyway Outline);
5CONS.DNF (Constellation names).

The Saturnian moons option is based on emperical formulae. All calculations 
are performed with 16 digit precision. We've done our best to achieve the 
most optimal performance in such a 'small' program. If you find any bugs, 
irregularities, just have smart ideas how expand the program or have even 
better algorithms, please contact us!

Thanks to all the testers (in particular John Davies and Uli Kudicke) and 
contributers out there, who have supplied ideas, support, bug-reports and 
other useful stuff.
