[ascl:2506.007] excalibuhr: High-resolution spectral data reduction

The excalibuhr end-to-end pipeline extracts high-resolution spectra designed for VLT/CRIRES+. The package preprocesses raw calibration files, including darks, flats, and lamp frames, and can trace spectral orders on 2D detector images. It applies calibrations to science frames, can remove the sky background by nodding subtraction, and combines frames per nodding position. excalibuhr can also extract 1D spectrum and perform wavelength and flux calibration.
