<p>This is the directory with the current PUEO antenna data files: <a href="https://github.com/PUEOCollaboration/pueoSim/tree/main/data/antennas" target="_blank">https://github.com/PUEOCollaboration/pueoSim/tree/main/data/antennas</a>. Each type of antenna will need several files:</p>
<ul>
<li>vv_0 and hh_0 describe the on axis v and h pol gain as a function of frequency. Gain is listed as a multiplicative factor (not in dB, if I'm remembering correctly)</li>
<li>hv_0 and vh_0 describe the on axis cross polarization gain</li>
<li>vv_az and hh_az describe the off-axis gain via multiplicative factors of the boresight gain. These are currently listed as a function of frequency for reference angles of 0,10,20,30,40,50,60,70,80, and 90 degrees, though we can always adjust the reference angles if needed.</li>
<li>vv_el and hh_el are similar to above, but for gain as a function of elevation angle instead of azimuthal angle.</li>
</ul>
<p>So for example, the total vpol gain in a particular frequency bin for a signal incident at azimuthal angle az and elevation angle el would be vv_0(f)*vv_az(f, az)*vv_el(f, el)</p>

<p>We can also potentially adjust this if it would be more convenient for the GENETIS people to output antenna information in a different format (or at different reference angles or whatever). The important thing is that the boresight h, v, and cross pol gains are all defined, as well as the off-axis response (as a function of azimuth and elevation)</p> |
