Parkes observations for project P960 semester 2021APRS_04

We aim to carry out receiver pointing and characterisation tests of Parkes receivers. Typically, these tests are carried out after the receiver package is installed, but time does not always allow for proper characterisation. Receivers for consideration include UWL, MARS, SX, K/KU-BAND and 13MM packages. In addition to cross-referencing C007 for flux calibration via pointing, we aim to conduct gain-elevation and system temperature experiments using the Moon, to ensure users of the Parkes Observatory have the most accurate information available for calibration purposes. We also wish to fully characterise the spectro-polarimetry response of the UWL, by determining the Mueller Matrix of the receiver.

本研究旨在开展帕克斯接收机（Parkes receivers）的指向测试与特性表征工作。通常这类测试会在接收机套件安装完成后开展，但受限于观测时长，往往无法完成完整的特性表征。本次待测试的接收机包括UWL、MARS、SX、K/KU波段（K/KU-BAND）以及13毫米波段（13MM）套件。除通过指向测试参照编号C007以完成流量定标外，我们还计划利用月球开展增益-仰角与系统温度实验，旨在为帕克斯天文台（Parkes Observatory）的使用者提供最为精准的定标参考数据。此外，我们还将通过测定该接收机的穆勒矩阵（Mueller Matrix），完整表征UWL接收机的光谱偏振响应特性。
