optimise - output data file formats
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
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
yagi(1), output(1), input(1), optimise(1), first(1), input(5),
output(5) and yagi(5).
