### GDF v1

The original GDF format contains visibilities consisting of:

- 7 data associated parameters, in a fixed order: `u, v, w, date, time, first antenna, second antenna`
- an array of complex visibility elements, that contain each a real part, an imaginary part and a weight

Note that in this original format, `u,v` and `w` are in meters, the `date` is a `CLASS` date, `time` is in seconds. The `w` column was often replaced by the scan number `scan` for flagging and editing purpose.
