An accurate line list, called XABC, is computed for nitric oxide which covers its pure rotational, vibrational and rovibronic spectra. A mixture of empirical and theoretical electronic transition dipole moments are used for the final calculation of $^{14}\mathrm{N}^{16}\mathrm{O}$ rovibronic $\mathrm{A}\,^2\Sigma^+$ — $\mathrm{X}\,^2\Pi$, $\mathrm{B}\,^2\Pi$ — $\mathrm{X}^2\Pi$ and $\mathrm{C}\,^2\Pi$ — $\mathrm{X}\,^2\Pi$ which correspond to the $\gamma$, $\beta$ and $\delta$ band systems, respectively, as well as minor improvements to transitions within the $\mathrm{X}\,^2\Pi$ ground state. The work is a major update of the ExoMol NOname line list. It provides a high-accuracy NO ultraviolet line list covering the complicated regions where the $\mathrm{B}\,^2\Pi$-$\mathrm{C}\,^2\Pi$ states interact. XABC provides comprehensive data for the lowest four doublet states of NO in the region of $\lambda > 160 ~ \mathrm{nm}$ ($\tilde{\nu} < 63~000~\mathrm{cm}^{-1}$) for the analysis of atmospheric NO on Earth, Venus or Mars, other astronomical observations and applications.
