VizieR Online Data Catalog: HAQ survey: red QSO candidates follow-up (Krogager+, 2015)

During a range of observing runs in 2012, 2013, and 2014, 159 candidate red QSOs were observed with the Nordic Optical Telescope (NOT) on La Palma, using the Andalucia Faint Object Spectrograph and Camera (ALFOSC). As in Paper I (Fynbo et al. 2013ApJS..204....6F), we used grism #4, which covers the wavelength range from about 3200 to 9100Å at a resolution of about 300 with a slit width of 1.3 arcsec. See section 3.
