This page summarizes results from TCAL0005.sb43136082.eb43148989.59934.06476138889, observed on December 21, 2022. The observations were performed in C configuration at L-Q bands. Here only Ka and Q-band are discussed.
Ka / Q
Standard calibration was performed using 3C286 as the bandpass and flux density scale calibrator, and J0319+4130 as leakage calibrator.
Full Stokes image cubes were generated for each spectral window, as well as images for the lower and upper half of the frequency ranges covered. Only values for point sources were extracted. We also observed MARS and URANUS

Stokes I information was obtained using imfit to the center of each image. Polarization information was obtained generating the polarized intensity maps from Q and U, then using imfit to fit a Gaussian to obtain the polarized intensity values. The Angle was obtained from the median value around the peak pixel obtained from the polarized intensity maps.
