      • getPointCount

        public int getPointCount()
        Description copied from interface: MultiPointCoordSet
        Returns the number of (non-central) data positions defined by this coord set.
        Specified by:
        getPointCount in interface MultiPointCoordSet
        Returns:
        data position count
      • readPoints

        public boolean readPoints​(Tuple tuple,
                                  int icol,
                                  DataGeom geom,
                                  double[] xyz0,
                                  double[][] xyzExtras)
        Description copied from interface: MultiPointCoordSet
        Reads the non-central points from a appropriate span of columns in a supplied tuple. The central data position must be supplied as input. The icol value gives the column corresponding to the first coord of this coordinate set in the sequence; the following few columns are assumed to correspod 1:1 to the coords in this coord set.
        Specified by:
        readPoints in interface MultiPointCoordSet
        Parameters:
        tuple - tuple
        icol - index of tuple field corresponding to the first of the coordinates in this set
        geom - converter between tuple values and data space coordinates; may not be required
        xyz0 - nDataDim-element array giving central data position
        xyzExtras - [nPointCount][nDataDim]-shaped array into which the non-central data positions will be written
        Returns:
        true iff the conversion was successful
      • createForm

        public static MultiPointForm createForm()
        Creates a MultiPointform that can plot vectors on the sky, corresponding to this coordset.
        Returns:
        new form
