"The determination of the black hole mass agrees beautifully with earlier measurements inferred from the velocities of stars," Ma Chung-Pei, a professor of physics and astronomy at University of California, Berkeley, told Xinhua. "Obtaining the same mass from two independent methods boost the confi...

In this state, the default number of the target star point is 1. The adjustable parameters are the Gaussian noise level of the image, the number of background stars, the maximum value of target brightness, and the minimum value of target brightness. Users can generate single-frame simulated ...
FIELD: instrument engineering.;SUBSTANCE: telescope can be used as auxiliary means of determining spacecrafts. Space telescope for observation of stars and the Earth includes Earth observation channel having main mirror, on part of which, closed with green reflecting light filter, light from the ...

On this basis, a comprehensive noise model of harsh environment is established by analyzing the generation mechanism of the transient effect, plume effect and the false stars which like star. At the same time, Gaussian noise and salt noise are used to pollute the star image. Finally, the ...
