15-18
Nb ― number of data bins along radials (see Note)
19-22
Nr ― number of radials
23-26
La1 ― latitude of centre point
27-30
Lo1 ― longitude of centre point
31-34
Dx ― spacing of bins along radials

40-(39+4Nr)
For each Nr radials:
(40+4(X-1)) - (41 +4(X-1)) Azi ― starting azimuth, degrees x 10 (degrees as north)
(42+4(X-1)) - (43+4(X-1)) Adelta ― azimuthal width, degrees x 100 (+ clockwise, - counter-clockwise,
with X = 1 to Nr


Note:

A data bin is a data point representing the volume centred on it.
