Functions double AcTan double sinx, double cosx Four-quadrant arctan function. Detailed Description The Satellites plugin displays the positions of artifical satellites in Earth orbit based on a catalog of orbital data.

Satellite Properties Name and identifiers Each satellite has a name. Grouping A satellite can belong to one or more groups such as "amateur", "geostationary" or "navigation".

Configuration The plug-ins' configuration data is stored in Stellarium's main configuration file. Type for sets of satellite group IDs. Defines the number and the order of the columns in the Iridium Flares table. Main configuration window of the Satellites plugin.

Radio communication channel properties. TLE update source, used only internally for now. Custom proxy model allowing filtering by satellite group and flag. In order to align the imagery more precisely on the dome I suggest turning on the azimuthal grid z key and look straight up. The pole can be aligned to the pole of the dome and the horizon line aligned to the rim of the dome. The scaling factor is essentially adjusting for the projector zoom and throw. For example, if the zoom is increased in the above configuration to 1.

When doing the alignment it is helpful to make the azimuthal grid as clear as possible. The following is one way to do this. I will not repeat the settings above that version 0. In the video section, most modern graphics cards and drivers have no issue with non power of two textures. Somewhat smoother operation can be achieved by matching the maximum frame rate to the vertical refresh of the projector, this is usually 60Hz and this should also be set in the monitors control panel for the display.

In any case, since locking to vertical refresh should be enabled to avoid tearing, there is no possibility of frame rates above the refresh setting of typically 60 to 85 Hz for digital displays and pretty much exclusively 60Hz for digital projectors. Notes: The flipping is rather redundant, one normally wants to see the image correct on the monitor and flipped digitally using the projector controls image flipping is supported in all known data projectors. In any case, the difference between the conventional definition and the one here is just a factor of the projector aspect ratio.

So commodity projectors depending on the zoom have a throw of between 1. In the above 2. Data projectors except for very wide angle lens generally have an offset lens. The degree of offset, except in projectors with mechanical lens shift, is fixed. Stellarium defines this offset as an angle, so for example in the above example with a throw of 2.

In the "standard" recommended arrangement of the mirror with respect to the dome, the radius of the dome is not relevant. The texture triangle length should be reduced to 4 or 8 for improved quality. While this should have little performance issues for modern hardware, it may well be an issue on some machine configurations.

Unfortunately the developers have chosen to implement their own warp mesh approach and file format rather the more general one employed by my existing software tools and implemented by other developers. This precludes the elegant idea of having one mesh file for all applications at a particular site. Fortunately the above geometric approach is perfectly satisfactory for standard dome configurations. Not a serious issue since one was quitting anyway, just an annoying error message. Stellarium configuration Unfortunately while the warping was never ideal, it is now broken on a couple of fronts.

My understanding is that the last correctly operating version in this regard was At the bare minimum they require a spherical projection and a landscape. Note that other projections are supported besides spherical, but that is the most general and recommended by the author.

An example is given in this zip file: polargrid. This version of Stellarium allows one to add the landscape through the gui rather than adding manually.

See "Sky and Viewing Options menu", and choose the "Landscape" tab. This is straightforward if you are using Mac OS-X, see the displays control panel. Creating and using a correct colour profile significantly improves the colour and contrast levels. In general data projectors have a very high or low depending on which way you define it gamma. Note also that by its very nature there is a lot of light inter-reflection inside a dome onto other surfaces of the dome. Naturally, these files are to be located in the Installation Data Directory because they ship with the installer.

The catalogue downloader tool runs within Stellarium. When it downloads extra star catalogue files, it should place them in the User Data Directory. After downloading all the catalogues, the paths to the various files should look like this:. It might be that someone makes a customised installer of Stellarium which includes all the star catalogues with the main installation - perhaps on a special edition DVD.

The downloader tool should be able to cope with this, not re-downloading files into the User Data Directory which already reside in the Installation Data Directory.

Stellarium HEAD. File and Directory Structure. Introduction This article explains the directory and file layout which Stellarium uses from a programmer's perspective, lays out the rationale behind it, and uses examples to illustrate the way things work. Directory Structure Files are broadly separated by the type of data. User and Installation directory separation When Stellarium searches for data, texture and other files it looks in two separate locations: The User Data Directory , which stores per-user copies of any customised data files.

Note that you may have to change explorer's settings so you can view hidden files before you can navigate to this directory. The main Stellarium installation directory is the Installation Data Directory. There are several reasons for doing this: On machines which multiple user accounts, the Installation Data Directory will likely not be writable by all users.

Without allowing the User Data Directory files to over-ride Installation Data Directory files such users could not customise the program without doing an entirely separate installation.
