CLASS supports 3 major switching modes (see the MRTCAL user
documentation for a more complete description):
- position switching (abbreviated into psw),
- wobbler switching (abbreviated into wsw),
- frequency switching (abbreviated into fsw).
The frequency switching mode can be divided into 2 subcategories:
- unfolded frequency switching (abbreviated ufsw),
- folded frequency switching (abbreviated ffsw).
Up to sep19 GILDAS version, CLASS used the same weighting definitions
for all switching modes. In particular for the TIME weights
