| Code figure | Meaning |
| 1 | The complex numbers Xnm, (see code figure 1, Code table 9) are stored for m >= 0 as pairs of real numbers Re(Xnm), Im(Xnm) ordered with n increasing from m to N(m), first for m = 0 and then for m = 1, 2, ... M. The real part of the (0,0) coefficient is stored in octets 12-15 of the Binary data section. The imaginary part of the (0,0) coefficient and the remaining coefficients are packed, and are stored in octets 16 onwards of the Binary data section. |
| 2 | Indicates spherical harmonics - complex packing. |
