Beam responses

Beam responses are given by mwa_hyperbeam. At present, only MWA beam code is used.

To function, MWA beam code needs a few things:

• The dipole delays;
• The dipole gains (usually dead dipoles are 0, others are 1);
• The direction we want the beam response as an Azimuth-Elevation coordinate; and
• A frequency.

In addition, the FEE beam code needs an HDF5 file to function. See the post-installation instructions for information on getting that set up.

Errors

Beam code usually does not error, but if it does it's likely because:

1. There aren't exactly 16 dipole delays;
2. There aren't exactly 16 or 32 dipole gains per tile; or
3. There's something wrong with the FEE HDF5 file. The official file is well tested.
