Abstract:
We present high-quality photometry in the five Sloan Digital Sky
Survey filters, u', g', r', i', and z', for 2195 galaxies with
spectroscopic redshifts measured by the Las Campanas Redshift Survey.
In addition, a polynomial photometric redshift estimator is derived,
with an uncertainty of 0.035 out to z=0.25.
