TL;DR: The Nuclear Spectroscopic Telescope Array (NuSTAR) as discussed by the authors is the first focusing high-energy X-ray telescope in orbit, which operates in the band from 3 to 79 keV.

TL;DR: In this article, a piece-wise linear spline function was proposed to modify the vignetting response of the nuclear Spectroscopic Telescope Array (NuSTAR) X-ray satellite.

TL;DR: In this paper, a piece-wise linear spline function was used to modify the vignetting response of the Crab as the primary effective area calibrator, and the achieved residuals for all off-axis angles and energies, compared to the assumed spectrum, are typically better than 2$\% up to 40\,keV and 5--10\,\% above due to limited counting statistics.

TL;DR: In this article, the authors reported the discovery of 3.76 s pulsations from a new burst source near Sgr A^* observed by the NuSTAR observatory, which is known as SGR J1745-29.
