So far, we have handled only Spectroscopic data, but Continuum data can be processed by CLASS . Currently, only continuum drifts can be reduced. The basic idea is to treat continuum drifts as spectra would be. Accordingly, very few commands behave differently in Continuum and Spectroscopy modes.
Continuum mode is accessed by typing command
SET TYPE CONTINUUM
the prompt changes to CAS> (Continuum Analysis System). You can
return to Spectroscopy mode later on typing command
SET TYPE SPECTROSCOPY or LINE
and the prompt changes to LAS> (Line Analysis System).
