## Skydip Processing

CLASS is able to reduce skydip data. Skydip mode must be selected using command SET MODE SKYDIP which also changes the prompt to SAS> (Skydip Analysis System). Commands FIND, HEADER, GET, PLOT and WRITE may be used as for Continuum and Line modes, but the only other valid command is REDUCE which fits the sky emission using atmospheric information available in the data, and displays the results.
