Detailed Description

Location vector.

Note

Helios uses a non-standard convention for longitude: positive values are in the Western hemisphere and negative values are in the Eastern hemisphere. The standard ISO 6709 / EXIF convention is the opposite (+E / -W). When this Location is written into EXIF metadata via the radiation plugin, the longitude sign is automatically flipped at that boundary.
