Workspace Method iyInterpCloudboxField
Description
Interpolates the intensity field of the cloud box. This is the standard method to put in iy_cloudbox_agenda if the the scattering inside the cloud box is handled by the DOIT method. The intensity field is interpolated to the position (specified by rtp_pos) and direction (specified by rtp_los) given. A linear interpolation is used for all dimensions. The intensity field on the cloux box boundaries is provided by *scat_i_p/lat/lon* and these variables are interpolated if the given position is at any boundary. Interpolation of the internal field is not yet possible.
