15 | Shape of the Earth (See Table 3.2)
16 | Scale factor of radius of spherical Earth
17-20 | Scale value of radius of spherical Earth
21 | Scale factor of major axis of oblate spheroid Earth
22-25 | Scaled value of major axis of oblate spheroid Earth
26 | Scale factor of minor axis of oblate spheroid Earth
27-30 | Scaled value of minor axis of oblate spheroid Earth
31-34 | Nx ― number of points along the x-axis
35-38 | Ny — number of points along the y-axis
39-42 | La1― latitude of first grid point
43-46 | Lo1― longitude of first grid point
47 | Resolution and component flags (see Flag Table 3.3)
48-51 | LaD ― latitude where Dx and Dy are specified
52-55 | LoV ― longitude of meridian parallel to y-axis along which latitude increases as the y-coordinate increases
56-59 | Dx ― x-direction grid length (see Note1)
60-63 | Dy ― y-direction grid length (see Note 1)
64 | Projection centre flag (see Flag Table 3.5)
65 | Scanning mode (see Flag Table 3.4)
66-69 | Latin 1 ― first latitude from the pole at which the secant cone cuts the sphere
70-73 | Latin 2 ― second latitude from the pole at which the secant cone cuts the sphere
74-77 | Latitude of the southern pole of projection
78-81 | Longitude of the southern pole of projection

Notes: 1. Grid lengths are in units on 10-3 m, at the latitude specified by LaD. 2. If Latin 1 = Latin 2, then the projection is on a tangent cone. 3. The resolution flags (bits 3-4 of Flag table 3.3) are not applicable. 4. LoV is the longitude value of the meridian which is parallel to the y-axis (or columns of the grid) along which latitude increases as the y-coordinate increase (the orientation longitude may or may not appear on a particular grid).
