We present the wavelength calibration of the Hamilton echelle spectrograph (the Lick observatory). The main problem of the calibration arises from the fact that thorium lines...
A high precision spectro-radiometer measuring total ultraviolet radiation from 290-450 nm was installed at Arrival Heights as a two month blind inter-comparison with the established measurement progra
The FOS_AGN atlas provides spectral FITS data and preview files for all successful pre-COSTAR spectra using the Faint Object Spectrograph of AGNs (Active Galactic Nuclei). A discussion of the uniform
