The Atacama Cosmology Telescope: Passband Measurements with an Analysis of Systematic Errors
Thomas Alford, Rahul Datta, Erminia Calabrese +14
We present measurements of the spectral response of the four Advanced ACTPol (AdvACT) multichroic detector arrays, which observed in frequency bands centered near 30, 40, 90, 150,…

Optical modeling of systematic uncertainties in detector polarization angles for the Atacama Cosmology Telescope
Colin C. Murphy, Steve K. Choi, Rahul Datta +10
We present an estimate of the Atacama Cosmology Telescope (ACT) detector polarization angle systematic uncertainty from optics perturbation analysis using polarization-sensitive ra…
