  Presented are measurements of the observed redshift-space galaxy-galaxy
autocorrelation function, xi(s), for the Las Campanas Redshift Survey (LCRS).
For separations 2.0/h Mpc < s < 16.4/h Mpc, xi(s) can be approximated by a
power law with slope of -1.52 +/- 0.03 and a correlation length of s_0 = (6.28
+\- 0.27)/h Mpc. A zero-crossing occurs on scales of roughly 30 - 40/h Mpc. On
larger scales, xi(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(s). Finally, the LCRS xi(s) is compared
with those from numerical simulations; it is concluded that, although the LCRS
xi(s) does not discriminate sharply among modern cosmological models,
redshift-space distortions in the LCRS xi(s) will likely provide a strong test
of theory.
