21-24 | P― Laplacian scaling factor
(expressed in 10^{-6} units) |

J_{s} ― pentagonal
resolution parameter of the unpacked subset (see Note1) |

27-28 |
K_{s} ― pentagonal
resolution parameter of the unpacked subset (see Note1) |

29-30 |
M_{s} ― pentagonal
resolution parameter of the unpacked subset (see Note1) |

31-34 |
T_{s} ― total number of
values in the unpacked subset (see Note1) |

35 |
Precision of the unpacked subset
(see Code Table 5.7) |

Notes:(1) The unpacked subset is a set of values defined in the same way as the full set of values (on a spectrum limited to J _{s}, K_{s}
and M_{s} ), but on which scaling and packing are not applied.
Associated values are stored in octets 6 onwardsof section 7. (2) The remaining coefficients are multiplied by (n x (n+1)) ^{p}
, scaled and packed. The operator associated with this multiplication is derived from the Laplacian operator on the sphere. (3) The retrieval formula for a coefficient of wave number n is then: Y = (R+X x 2 ^{e} ) x 10^{-d}
x (n x(n+1))^{-p} where X is the packed scaled value
associated with the coefficient. |
