| #### Type 1000 Type 1000 files contain a one-dimensional array of data values. Typically they relate to the same physical quantity; examples are continuously-digitized data, a power spectrum, or a correlation function. The header for Type 1000 files contains physical abscissa (i.e., x-axis) information: physical abscissa units (e.g., time, frequency, delay, timecode) physical abscissa starting value physical abscissa increment This lets primitives compute the physical abscissa value corresponding to any data element in the file. Referring to data elements by its abscissa location is called abscissa addressing, in contrast to index addressing which designates data elements by their index in the file. #### Type 1999 Type 1999 files are a special form of type 1000 files. Plottable type 1999 files (like map1 or map2) have the form:
      # Real          Imag
      - ----          ----
      1 # block pts   -999
      2 min_blk_lon   min_blk_lat
      3 max_blk_lon   max_blk_lat
      4 # pts         color #
      5 min_lon       min_lat
      6 max_lon       max_lat
      7 lon1          lat1
               ...
      n lonN          latN

      The -999 as the first entry in the IMAG column is used to tie blocks
      of points together.

      A simpler form of 1999 file is:

      # Real     Imag
      - ----     ----
      1 #pts     color #
      2 min_lon  lat_min
      3 max_lon  max_lat
      4 lon1     lat1
      5 lon2     lat2
            ...
      n lonN     latN
