It is important to note that lget searches for the first scan covered by the rest frequency. Other scans covering the same frequency are ignored. Thus if you have a spectral survey with several scans covering the same frequency, it is recommended to average these scan together with the CLASS average beforehand.

... command5
Alternatively, one may retrieve the predicted spectrum with retrieve TA_MODEL, and plot it over the observed spectrum with spectrum. However, it is important to fix y axis range; if the axis is set to auto, then the predicted and modeled spectrum will not be on the same scale, and the comparison will be meaningless. The modshow command ensure that both the observed and predicted spectrum are on the same scale.
