Beam reconstruction

During the scientific flight, Jupiter was observed twice with an interval of roughly two hours. We use Jupiter to obtain maps of our beams as its angular size (around 40 arcsec) is much smaller than our angular resolution. The beam maps for all off our bolometers are shown in Figure . We obtain an average angular resolution of around 12 arcminutes, larger than expected due to the large time response of the bolometers that can be seen in the figure on left side of each beam.
