 Keyword  Posn   Type       Description
 -------  ----   ----       -----------
 INP         1   UNIV       Input event dataset.
             -GLOBAL.EVDS (Default event dataset)
 OUT         2   UNIV       Name of the output binned dataset.
            ->GLOBAL.BINDS (Default binned dataset)
 LISTS       3   CHAR       Index numbers of the lists to use in the
                            polaring. Separate by spaces, eg. 1 2
 X0, Y0      -   REAL       The coordinates of the pole in the same
                            units as the selected axes.
       Defaults 0,0
 The following 2 parameters only apply if a QUALITY list is present
 in the input.
 QVAL        -   INTEGER    Events with QUALITY greater than QVAL
                            will be treated as BAD QUALITY data.
     Hidden default = 0
 QKEEP       -   LOGICAL    Write BAD QUALITY data to output
                            dataset?
    Hidden default = NO
 ABINSIZE    -   REAL       The azimuthal bin size in degrees.
         Default 360
 REG         -   LOGICAL    Specify regular radial bins?
    Default YES
 RBINSIZE    -   REAL       Radial bin size if REG is YES. In same
                            unit as input lists
 NRAD        -   INTEGER    Number of radial bins. The first bin
                            has a lower bound of zero. Only used if
                            REG is YES.
 RRANGE      -   CHAR       Used if REG is NO. A list of radial
                            bin boundaries. See ASTHELP USER_INTERFACE
                            LIST_AND_RANGES for syntax.
 NORM        -   LOGICAL    Normalise output array - ie. divide by
                            bin area.
     Default YES
