The Q/U Imaging ExperimenT (QUIET), a ground-based experiment located in the Atacama Desert in Chile, measures the polarization of the Cosmic Microwave Background (CMB). In Phase I, it measures the CMB polarization at angular scales of 25 (see manuscript) l (see manuscript) 1000 using radiometer arrays in the Q (44 GHz) and W (95 GHz) frequency bands. The Q-band and W-band receivers of Phase I of the QUIET instrument contain 2 and 6 total power modules (TT modules), and 17 and 84 polarization modules respectively. Responsivities for the TT modules are obtained primarily from Jupiter and skydip measurements, using Jupiter as the absolute calibrator and the more frequent skydip measurements to track short time-scale fluctuations over the course of the season. Responsivities for the polarization modules are obtained from Tau A, relative measurements from the Moon, a polarizing wire-grid, and skydips. Skydips are used to track the responsivity of the polarization modules on a shorter time-scale.
