Scientific paper

The Las Campanas Fiber-Optic Redshift Survey (LC) now contains over 20000 galaxies, with an average redshift z ~ 0.1, distributed over six 1.5deg by 80deg strips in the Northern and Southern galactic caps. We have computed the power spectrum for magnitude-limited samples of LC galaxies over scales lambda = 5 - 600\ h(-1) Mpc, and find a good match to the power spectrum of a cold dark matter model with Omega h ~ 0.3. Comparisons with other redshift surveys give generally fair agreement, and specific details will be presented. Comparison to COBE results shows a bias b ~ 1 for LC galaxies relative to the mass on scales lambda > 100\ h(-1) Mpc. Power spectrum measurements for volume-limited LC samples show that galaxies brighter than about M(*_) LC-1.5 (M(*_) LC = -20.3) appear more strongly clustered than those fainter.
