This file is a Starry Night document.
// Part 1
// Pano name - you see this in menus, etc. This should be unigue for each pano.
// Change value="Earth Wellington" to a name that describes your image. For examplevalue="MyHorizon". The name you choose will appear in the drop box in the Horizon Options window.
// Change value="00_Earth_Wellington.png" to the name of the PNG image you made and placed in the Horizon Panoramas folder. For example if you named your image "MyHorizon.png", change it to value="MyHorizon.png".
// Both the image and text file must be located in the Horizon Panoramas folder.
// Part 2
// Planet that panorama is associated with (in this case this panorama is only appropriate for the Earth)
// Part 3
// In degrees, the height of the image. This value specifies the height of the image in degrees. A value between 45-55 is about right for most images.
// Part 4
// If the image has an alpha channel that is set up with the sky having an alpha of 0 and the horizon an alpha of 1,
// with alpha blending at the interface, we need to say Yes here, otherwise say "no"
// Leave this value as yes if you added an Alpha channel.
// Part 5
// These values are in the coord system that you pick out with ImageCoordSys
// Part 5
// Think of ImageCentreDec as degrees Up and Down.
// A value of -11.0 means that the centre of your image lies 11 degrees below Starry Night's formal horizon line.
// SN's formal horizon line lies at 0 degrees Altitude as you may expect.
// Use this value to adjust your panorama until it looks right against the sky.
// You can even set this precisely by recording the actual rise or set time of a certain star/planet over a given obstacle in your panorama -e.g. a mountain peak- and set the ImageCentreDec so that it appears the same in SN.
//Think of ImageCentreRa as Left and Right. Adjust this value if your image is facing towards the incorrect cardinal direction.
// Part 6
// These are also in ImageCoordSys coordinate system.
// They determine where the image will be.
// If you're not sure do not make any changes here.
// Part 7
// Adjusts the brightness of your horizon. The panorama brightness will be scaled with this value, up to a maximum of 1.0 (100%). If you want your panorama to appear half as bright, use a PanoBrightness value of 0.5 (50%).
// Part 8
// Used during liftoff to draw a horizon nicely. Ignored for panos like the milkyway which are always far off.
// Part 9
// Used during liftoff to draw a horizon nicely. Ignored for panos like the milkyway which are always far off.
// the color is red, green, blue, with each value scaled 0 to 65535
// Part 10
// If preload is set, will load image on startup.
// You can have multiple images preloading when the program starts. However, this will increase the time that it takes for Starry Night to load.
// Ideally you only want one image to have a preload value of ‘Yes’, the one you use most often.
// In addition, when Starry Night loads, the horizon that is displayed by default is the one whose accompanying text file was read first in alphanumeric order from the Horizon Panoramas folder.
// If you want your panorama image to load first, give it a preload value of ‘Yes’ and name the text file so that it is listed first in alphanumeric order, such as Earth_00MyHorizon.txt.
