public class Scan
extends LabeledLink
Source scan information class. This class contains the information for the scheduling of VLA observations of a given source. Everything is public to facilitate the translation from c.

Scans are linked using their LabeledLink/Linkage members. Note, however that the head of the list is type LabeledLink and not a Scan. Also since the lists are circular the list ends when it gets back to the (non Scan) head. Looping over the list should be done using the LabeledLink superclass.

This class corresponds to SrcStructure in the old C Observe.
