       nms    Number  of MeasurementSets to create (0 means 1 MS without suffix; default, >0 also
              creates MultiMS)

              if not given)

       startfreq

       timestep
              Time interval (sec; default: 1)

       ntime  Number  of time steps (default: 1) ntimefield Number of time steps per field (0=all
              fields for all times; default)

       nspw   Number of spectral windows (default: 1)

       npol   Number of polarizations per spectral window; 1 value applies to all spws  (default:
              4)

       nchan  Number of channels per spectral window; 1 value applies to all spws (default: 256)

       nant   Number  of antennae to use; it anttab is given maximum to use is its size (default:
              0)

       calcuvw
              Calculate UVW coordinates? (default: false)

       autocorr

       imagercolumns
              Write imager columns (MODEL_DATA, CORRECTED_DATA)? (default: false)

       rowwise
              Write the data row wise (thus a put per row) (default: true)

       nflagbits
              int Write multiple flag bits (0, 8, 16 or 32) mapped to FLAG (default: 0)

       flagcolumn
              Name of the FlagBits column if nflagbits>0 (default: "FLAG_BITS")

       multihdf5
              Use the MultiHDF5 feature? (default: false)

       mfsize MultiFile/HDF5 block size (KBytes); default is tilesize

       ashdf5 bool Write the data in HDF5 format (default: false)
