QSO search by slitless spectroscopy*
Published online by Cambridge University Press: 19 July 2016
Extract
Sandage and I have obtained “grism” plates that redundantly cover one square degree fields centered on ten Selected Areas. We used a grating-prism in the converging beam of the Mayall 4-meter telescope prime focus to photograph 1580 A·mm−1 slitless spectra to a limit of about B = 21.5 (cf. Hoag and Smith 1977).
