:Datasets: - **g_out bounds** (*int[2]* or *int[][][2]) --
Minimum (most energetic) and maximum (most thermal) outgoing groups
with non-zero values of the scattering matrix. These group numbers
use the standard ordering where the fastest neutron energy group
is group 1 while the most thermal neutron energy group is group G.
:Datasets: - **g_min** (*int[]* or *int[][][]) --
Minimum (most energetic) outgoing groups with non-zero values of
the scattering matrix. These group numbers use the standard
ordering where the fastest neutron energy group is group 1 while
the slowest neutron energy group is group G.
The dimensionality of `g_out bounds` is:
`g_out bounds][g_in][g_out]`, or
`g_out bounds[num-polar][num-azimuthal][g_in][g_out]`.
`g_min[g_in]`, or `g_min[num-polar][num-azimuthal][g_in]`.
The former is used when `representation` is "isotropic", and the
latter when `representation` is "angle".
- **scatter matrix** (*double[][]* or *double[][][][]*) --
Flattened representation of the scattering moment matrices where
the [g_in] and [g_out] indices are flattened. The pre-flattened
array is shaped as follows (in row-major format):
- **g_max** (*int[]* or *int[][][]) --
Maximum (least energetic) outgoing groups with non-zero values of
