HELP SECTION

DOSCAN
Type:   Adverb  (logical,  > 0  =>  true)
Use:    Tells a task to perform some operation on a "scan" basis.
        Scans are defined as entries in an index (NX) table attached
        to a UV data set.  What is a "scan" may change in that AIPS
        automatically recomputes the NX tables and assigns a new scan
        only when a source changes or a large gap in time occurs.
Null value:  false (-1).
Tasks:
  SNBLP........Plots selected contents of SN or CL files on a baseline
               basis.  DOSCAN controls whether scan boundaries are
               plotted on plots with time as the X axis.
  SNPLT........Plots selected contents of SN, TY, PC or CL files.
               DOSCAN controls whether scan boundaries are plotted on
               plots with time as the X axis.
  SYVSN........Plots selected SY/TY data with SN solution values
               versus time.  DOSCAN controls the sort of plot at
               scan boundaries if any.
