Calibrate K-band data

Calibration at K-band can be challenging. This is because at these high frequencies the atmosphere in which the faint radio signals must travel becomes a problem. These issues need to be calibrated out before we can process the data.

At 22 GHz, there are few sources in the Southern Hemisphere bright enough to be detected by the HartRAO 26m antenna. For this reason, we use the planet Jupiter to calibrate our sources.
