| dc.description | A potential problem with using wide-field multi-object spectrographs for quasar redshift surveys is the introduction of position-dependent selection effects into the survey catalogue because of variations in the observed signal-to-noise ratio (SNR) across the survey area. A function relating signal losses in instruments using optical fibre input to the fibre-to-image position error, the fibre diameter and the seeing conditions is given and plotted for a range of typical values of fibre sizes and seeing found in current instruments. | |
