       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 input files required for optimise are plain ASCII which can be generated by input or  first.
       or  may  be  generated  manually  with a text editor, if care is used. The format required by optimise is
       described in input(5). Optimise's output files, which have the .bes extension are the same format as  the
       input files and are again obviously 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 4 element 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 file

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