Presented are measurements of the observed redshift-space galaxy-galaxy autocorrelation function , \xi _ { gg } ( s ) , for the Las Campanas Redshift Survey ( LCRS ) .
For separations 2.0 h ^ { -1 } Mpc < s < 16.4 h ^ { -1 } Mpc , \xi _ { gg } ( s ) can be approximated by a power law with slope \gamma = -1.52 \pm 0.03 and correlation length s _ { 0 } = 6.28 \pm 0.27 h ^ { -1 } Mpc .
A zero-crossing occurs on scales of \sim 30 - 40 h ^ { -1 } Mpc .
On larger scales , \xi _ { gg } ( s ) fluctuates closely about zero , indicating a high level of uniformity in the galaxy distribution on these scales .
In addition , two aspects of the LCRS selection criteria – a variable field-to-field galaxy sampling rate and a 55 arcsec galaxy pair separation limit – are tested and found to have little impact on the measurement of \xi _ { gg } ( s ) .
Finally , the LCRS \xi _ { gg } ( s ) is compared with those from numerical simulations ; it is concluded that , although the LCRS \xi _ { gg } ( s ) does not discriminate sharply among modern cosmological models , redshift-space distortions in the LCRS \xi _ { gg } ( s ) will likely provide a strong test of theory .
