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:
   BPPLT.........Plots selected contents of bandpass (BP) files versus
                 time.
   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.
   TEPLT.........Plots selected contents of TE (TECOR) parameter tables.
   VLBRF.........Plots spectral statistics of VLBA autocorrelation data
                 for RFI.  DOSCAN controls whether statistics are done
                 over all time or over each scan (and then averaged).
