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 toseparate the field and globular cluster (GC) populations. GCs with LMXBs havethe same radial distribution as the parent red and blue GCs. The radial profileof field LMXBs follows the V-band profile within the D25 of NGC 4649. Using thespatial information provided by our data, we find that the global galaxy-widerelations between cumulative number and luminosity of LMXBs and the integratedstellar mass hold on local scales within D25. An excess of field LMXBs withrespect to the V-light is observed in the galaxy's outskirt, which may bepartially due to unidentified GC sources or to a rejuvenated field LMXBpopulation caused by past merging interactions.
