System noise temperature Anh Phan, Yanlin Wu 10/17/2019
Methods • Noise sources and daytime data are masked. • Filter out high frequency components in the visibility with a Fourier low pass filter to get a fit of the raw data. • The rms of the residuals (raw data minus fit) is calculated.
Autocorrelation from raw 2018 data • Histogram for 32 auto-correlation baselines. • Middle frequency channel (255).
rms of residuals (raw data, 1s bin, no freq binning)
From Eq. 3 From Eq. 5 • Histogram for 480 cross-correlation baselines. • Middle frequency channel (255). From Eq. 3
Uncalibrated system temperature vs. integration time From Eq. 4
