Description
The main aim for the next generation of Cosmic Microwave Background (CMB) experiments is the detection of B-mode polarisation; a discovery that will serve as a smoking gun for the theory of inflation. While these experiments are well optimized for observing polarized emission, they must also mitigate the effects of numerous systematics to be able to achieve their target sensitivities. One such effect is gain uncertainty, which can make it difficult to calibrate the instruments with the required precision if it is not handled correctly. In this work, I develop a simulated pipeline to explore the effects of instrumental scanning strategies on gain estimation. The scanning strategy is developed from extracting Euler angles from rotation matrices. I create simulated time ordered data, using several scan strategies and including the effects of correlated noise. Then, using the Commander codebase (Galloway et al. 2023), I create maps of the sky signal and measure the resulting calibration factors to quantify their uncertainty and better quantify the effects of scanning strategy on gain estimation.
