- The mapmaking involves getting together the details of the pointing direction of the telescope at a given time with the time-ordered data, allowing the reconstruction of a sky map. Some effects must be considered, such as the distortions introduced by the telescope beam and the gathering of the multiple horns to form one final image of the sky.
- The component separation is the set of methods used to separate the HI signal, which contains information about the BAO, from the contaminants, such as galactic signals or the cosmic microwave background (CMB).
- The instrumental noise is the signal that was not captured directly in the detector but appeared in the final results. This is the main effect of the electronic circuits, which produce white noise and 1/f noise, and must be taken into account in the analysis.
- The bispectrum is a statistical quantity used to detect the non-gaussianity present in the maps, which can probe the distribution and behavior of the HI in our Universe.
