  We investigate the radial distribution of the low-mass X-ray binary (LMXB)
population in the elliptical galaxy NGC 4649, using Chandra and Hubble data to
separate the field and globular cluster (GC) populations. GCs with LMXBs have
the same radial distribution as the parent red and blue GCs. The radial profile
of field LMXBs follows the V-band profile within the D25 of NGC 4649. Using the
spatial information provided by our data, we find that the global galaxy-wide
relations between cumulative number and luminosity of LMXBs and the integrated
stellar mass hold on local scales within D25. An excess of field LMXBs with
respect to the V-light is observed in the galaxy's outskirt, which may be
partially due to unidentified GC sources or to a rejuvenated field LMXB
population caused by past merging interactions.
