Quasar Target Selection Fiber E ciency

We present estimates of the e ciency for nding QSOs as a function of limiting mag nitude and galactic latitude From these estimates we have formulated a target selection strategy that should net QSOs in the north galactic cap with an average of bers per plate not including bers reserved for high redshift quasars With this plan we expect of the targets to be QSOs The North Galactic Cap is divided into two zones of high and low stellar density We use about ve times as many bers for QSO candidates in the half of the survey with the lower stellar density as we use in the half with higher stellar density The current plan assigns of the bers to FIRST radio sources if these are not available those bers would be allocated to lower probability QSO sources dropping the total number of QSOs by a small factor We will nd about additional quasars in the southern strips and maybe a few more at very high redshift Use was made of two data sets the star and quasar simulated test data generated by Don Schneider and the data from UJFN plate surveys by Koo and Kron This data was compared to results from the Palomar Green Survey and a recent survey by Pat Osmer and collaborators
