GONG Image Geometry description
There is a great deal of information contained within the header of a GONG image. Most users of GONG images will want to know:
- The image geometry: what is the size and shape of each solar image, and where it is within the frame.
- Where are Solar north, south, east and west? (GONG Image Orientation)
- Ephemeris information -- i.e. the Solar Coordinates at the time the image was recorded.
Most of this information is provided in the header of every GONG image.
Sample image headers for each "flavor" of GONG image can be viewed by following the links given below:
