Dear ARTS community,
I am dealing with scattering situations and have used the iyFOS method in Arts-2.2 version, but there is no FOS method in Arts-2.4. May I ask if the method name has changed? I know and have consulted relevant literature on MC and DOIT methods, but is there any reference to FOS methods? Looking forward to your reply！Thank you! Best wishes, Jiaan He
