# Version 3 alpha 0.0.5

## Add comet database, labels, more printing functions.

Add Comet database.
That work the same way as for the Asteroids, see Version 3 alpha 0.0.4 for more details.

If you already create the asteroid database please click the “Create Database” button again to upgrade.

A sample data file (now in data/planet directory) load the currently visible comet. You can load new data from:
ftp://cfa-ftp.harvard.edu/pub/MPCORB/COMET.DAT
or from
http://cfa-www.harvard.edu/iau/Ephemerides/Comets/SoftwareComets.html
get the MPC Format file.

On Windows be sure to convert the end of line character. A download facility will be available in a future version to ease this process.

Object label.
About the same principle as in v2.75, using Greek letter for the Bright Stars.
But you can now move the label or edit the text by using a right mouse click to any label.
A left mouse click give you the detailed information about the object.
The changed label are saved to the default option or the saved chart.

Printing
Printer selection menu now offer the choice to print directly to a real printer or to produce file in Postscript or BMP format.
This give high resolution image of the chart, also with the same aspect as on the screen.
You can set an application to immediately process or print the image.

There is a new option to use the apparent coordinate instead of the mean coordinates. This apply correction for both the nutation and abberation to get the precise Earth related position.

Many default option have changed, some to correct bug or imprecision, so I recommand you delete (or copy to a safe place) the file .cartesduciel.ini before to run this version.
