     optimise - output data file formats


DESCRIPTION

     This manual page describes the output formats of  the  files
     created by the Yagi-Uda project's optimise program. The files
     are ASCII file, so can be analysed with any  graph  plotting
     program.  Its  input  file is the same format as required by
     yagi and is created input or first.  This  is  described  in
     input(5). Here we only describe the output data file format.
     The .bes output file, which is the same format as the  input
     file is obviosly described by input(5).



Example of a .up file.

     The .up file list the improvements made by  optimise  to  an
     antenna  design. Starting from the original design, the file
     is appended each time a new better design is found. Here  is
     an  example,  where the final line is the performance of the
     4ele beam with the .dat file shown earlier.
         1 7.57dBi,  16.93dB F/B, Z=(31.77-56.34j) Ohms, SWR=3.95, SL=16.95 dB
        84 7.58dBi,  16.93dB F/B, Z=(31.78-56.32j) Ohms, SWR=3.95, SL=16.95 dB
       623 7.58dBi,  16.93dB F/B, Z=(31.78-56.28j) Ohms, SWR=3.95, SL=16.95 dB
     89345 9.74dBi, 103.06dB F/B, Z=(37.55 +1.61j) Ohms, SWR=1.33, SL=17.78 dB



What is what in the .up

     The first column is an integer specifying the iteration. The
     other  columns,  goinf from left to right are gain(dBi), FB,
     input impedance, SWR  and  level  of  the  most  significant
     sidelobe, in dB down on the peak gain.
