Session 7 - Catalogs & Surveys.
Display session, Monday, January 13
As a preliminary step in a southern-hemisphere survey (i) for quasars of redshift 4.5>z>7, and (ii) for faint, red, high-latitude stars, we have made experimental observations of standard stars and sequences spanning a total range of 15 magnitudes through the Johnson and Gunn-Thuan filter systems.
We report preliminary Gunn-Thuan magnitudes for the stellar sequence near NGC300 observed in UBVRI by Walker (PASP,100,949;PASP,107,683). Our work is approximate, but of sufficient precision for the purposes of this survey.
