Asteroid Investigation
Downloads
This section is current as of May 2008. If Astrometrica does not work for you and it is well beyond this date, you may need to check the Astrometrica home page for updates.
From here you can download everything you need in order to get you started with the asteroid project.
- Download Astrometrica
You can download Astrometrica from the Astrometrica home page, or simply right-click and Save Target As... this link to the package created specifically for this project. This package is called Astrometrica.zip and is 21.4Mb in size. The MPCOrb database (October 2007) is already included in this package and is perfectly acceptable for the practice data here. However, if you are going to observe new asteroid data, you should update the database or download the latest version.
- Installing Astrometrica
If you have right-clicked and saved the package created specifically for this project, all you have to do to install is to unzip the file. You might want to move the resulting Astrometrica folder to the C:\Program Files\ directory and create a shortcut to place on your Desktop. Once you have placed the folder where you want it, to start Astrometrica you simply double click Astrometrica.exe. The first thing you should then do is set up Astrometrica so that it knows where to find the files it will need to access.
- Downloading Practice Data
One of the best ways to learn how Astrometrica works and how to analyse your asteroid data is to practice on some real data! Please download the following data sets for three asteroids from the Faulkes Telescope North. Create folders C:\DATA\FAULKES\Asteroids and unzip the data sets to the Asteroids folder. The numbered images (EY-1.fit) are all taken through the V filter. The sequence of images in order is asteroid-1.fit ....... asteroid-n.fit, asteroid-V.fit, asteroid-B.fit, asteroid-R.fit.
| Asteroid 2007EY | 9.7 MB | A relatively slow-moving asteroid. |
| Asteroid 2007EL88 | 3.8 MB | A very fast-moving asteroid whose orbit was highly uncertain at the time the data was taken. Note: The asteroid only appears in images EL88-1 through EL88-4. Unfortuately there are no B or R images as the asteroid disappeared from view before they could be taken. |
| 7.2 MB | Another relatively slow-moving asteroid heading in a different direction to asteroid 2007EY.

- Download IRIS
This is only required if you wish to make a colour image of your asteroid.
