Below is an example using 4 antenna (ant0, ant1, ant2, ant3) example and 4 polarisations (xx,xy,yx,yy) in one time step / integration (we only have time step per HDU). The ImgHDU data for the weights would like the following:
| antA | antB | weight.xx | weight.xy | weight.yx | weight.yy |
|---|---|---|---|---|---|
| 0ant0,ant0 | 0 | w | w | w | w |
| 0 | ant0,ant11 | w | w | w | w |
| 0 | ant0,ant22 | w | w | w | w |
| 0 | ant0,ant33 | w | w | w | w |
| 1 | ant1,ant11 | w | w | w | w |
| 1 | ant1,ant22 | w | w | w | w |
| 1 | ant1,ant33 | w | w | w | w |
| 2 | ant2,ant22 | w | w | w | w |
| 2 | ant2,ant33 | w | w | w | w |
| 3 | ant3,ant33 | w | w | w | w |
