Abstract:
We present UBRI photometry and spectra for 60 quasars found within
1°2 centered on the J0053+1234 region, which has been the
subject of the Caltech Faint Galaxy Redshift Survey. Candidate quasars
were selected by their ultraviolet excess with respect to the stellar
locus and confirmed spectroscopically. The quasars span a wide range
in brightness (17.5<B<21.6) and redshift (0.43<z<2.38).
Description:
We used the Kitt Peak National Observatory (KPNO) 0.9m telescope with
the CCD Mosaic Wide-Field Imager to acquire UBRI observations of the
1°2 region centered on the J0053+1234 region (RA=00h53m23.2s,
DE=+12°33'58") during 1998 September 30-October 2 UT, under
generally good observing conditions.
