Propmat

class pyarts3.arts.Propmat(*args, **kwargs)

A single propagation matrix.

Due to the properties of a propagation matrix, only 7 independents need be stored. The propagation matrix is thus represented as:

\[\begin{split}\mathbf{K} = \left[ \begin {array} {rrrr} A & B & C & D \\ B & A & U & V \\ C &-U & A & W \\ D &-V &-W & A \end {array} \right]\end{split}\]

This type is related to Stokvec in that its first 4 elements are the same as the first 4 elements of Stokvec for pure clearsky radiative transfers.

This type is also related to Muelmat because it is computed often as the exponent of this term multiplied by a negative distance.
