Antenna 6 gain calibration varying with time

I have been taking observations with the 6D configuration. Following calibration, I am finding that for the phase calibrator, the baselines containing antenna 6 have an amplitude and phase that seems to vary with elevation over time. Meanwhile, all the other baselines are flat as expected. See the a...

Flux and bandpass calibration using secondary following block drop

Hi all, I had a drop block during one of my observations before I had the chance to observe 1934. I was observing at both 4cm and 15mm so I am using 1934 for both flux and bandpass calibration. It was block 21 so I had to rerun dcal when the block was back online. As a result, the 1934 observations ...
