     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 manu-
     ally 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

     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.
