Measuring Track-Related Pointing Errors on the Nanshan Radio Telescope with an Optical Pointing Telescope

Figure 4

A preview of the radio and OPT pointing data, along with the pointing models fitted by the data. The (a) displays the azimuth pointing error, and the (b) the elevation pointing error. The red triangles indicate the ex and ey data of OPT in Table 2, and the corresponding red line is the pointing model based on that data. The black dots are the radio pointing data observed on 02-JUN-2020. The black line is the radio pointing model on the elevation of OPT observation.
