Frequently Asked Questions¶
Q: What is the base-data package?¶
base-data package is required for Gaia Sky to run and contains basically the Solar System data (textures, models, orbits and attitudes of planets, moons, satellites, etc.). You can’t run Gaia Sky without the
Q: Why do you have two different download pages?¶
At the end of the day, if you use the download manager of Gaia Sky, you will never see any of these. If you want to download the data manually, you can do so using either page.
Q: Why so many DR2 catalogs?¶
We offer 9 different catalogs based on DR2. Only one should be used at a time, as they are different subsets of the same data, meaning that smaller DR2 catalogs are contained in larger DR2 catalogs. For exmaple, the catalog
dr2-default is contained in
dr2-verysmall is contained in
dr2-default, and so on. We offer so many to give the opportunity to explore the DR2 data to everyone. Even if you have a potato PC, you can still run Gaia Sky with the
dr2-verysmall dataset, which only contains the very best stars in terms of parallax relative error. If you have a more capable machine, you can explore larger and larger slices and get more stars in.
Q: Gaia Sky crashes on start-up, what to do?¶
Most crashes are due to inconsistencies in the data. Usually, removing the data folder (
~/.local/share/gaiasky/data on Linux,
%userprofile%\.gaiasky\data on Windows,
~/.gaiasky/data on macOS) solves the problem. When Gaia Sky starts again, the download manager pops up for you to redownload the data.
Another, more sophisticated way of doing it is to launch Gaia Sky forcing the download manager,
$ gaiasky -d
and then deleting and redownloading each of the datasets from there, starting by the
Getting a crash log
If the crash remains, we need a log. If you are using version
2.2.0 or newer, or the development version on the
master branch, crash reports are saved in
~/.local/share/gaiasky/crashreports (Linux) or
~/.gaiasky/crashreports (Windows and macOS). Files starting with
gaiasky_crash_* are crash reports, while files starting with
gaiasky_log_* are full logs. Send us the relevant files.
If you are using another version of Gaia Sky (
2.1.7 or older), getting a log differs depending on your Operating System.
On Linux, just run Gaia Sky from the command line and copy the log.
On Windows, files named
error.log should be created in the installation folder of Gaia Sky. Check if they exist and, if so, attach them to the bug report. Otherwise, just open Power Shell, navigate to the installation folder and run the
gaiasky.cmd script. The log will be printed in the Power Shell window.
On macOS, open a Terminal window and write this:
$ cd /Applications/Gaia\ Sky.app/Contenst/java/app $ chmod u+x ./gaiasky $ ./gaiasky
This will launch Gaia Sky in the terminal. Copy the log and paste it in the bug report. Here is a video demonstrating how to do this on macOS.
Once you have a log, create a bug report here, attach the log, and we’ll get to it ASAP.
Q: I can’t see the elevation data on Earth or other planets¶
First, make sure you are using at least version 2.2.0. Then, make sure that your graphics card supports tessellation (OpenGL 4.x). Then, download the High-resolution texture pack using the download manager and select
Ultra in graphics quality. This is not strictly necessary, but it is much better to use higher resolution data if possible. Finally, select Tessellation in the “Elevation representation” drop-down of the graphics pane in the settings window. See Elevation representation.
Q: What is the internal reference system used in Gaia Sky?¶
Q: Can I contribute?¶
Yes. You can contribute translations (currently EN, DE, CA, FR, SK, ES are available) or code. Please, have a look at the contributing guidelines.
Q: I like Gaia Sky so much, can I donate to contribute to the project?¶
Thanks, but no.
