Continuum

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 the SET TYPE CONTINUUM command. The prompt then changes to CAS> (Continuum Analysis System). You can return to Spectroscopy mode later on typing the SET TYPE SPECTROSCOPY or LINE command and the prompt changes to LAS> (Line Analysis System).

Some commands have slightly different behaviour in Spectroscopy and Continuum modes.

Except for these restrictions, the behaviour of other commands is similar. Note that command FIND only selects data of the current type.
