Advanced Telescope Performance and Observing Capabilities Overview

This document provides an overview of the current capabilities and performance metrics of the telescope, focusing on its all-sky pointing accuracy with a root mean square (rms) of approximately 10” and a tracking stability rms of ~2” (5” peak-to-peak). It includes empirical modeling of focus tracking at 800 MHz in Gregorian X-band. Surface efficiency measures at long wavelengths are around 70%, decreasing to ~60% at 20 GHz. The telescope supports various observing modes, including continuum, pulsar, and spectral line observations, highlighting contributions from notable authors like Camilo and Lockman.
