Tomsick et al. 2016 (ApJ):
  • Multiple Chandra source within IBIS error circle, CXOU J180839.8-274131 is the most likely X-ray counterpart
  • Chandra and INTEGRAL spectra have different spectral slopes. Joint fit => Γ=-1.5 ; Efold=~5 keV, NH < 7e21 cm-2
  • Chandra light curves show variability, candidate period between 800 and 950s
  • Identification with OGLE-BLG-RRLYR-14363 which has a 0.28494563 d periodicity in the I band
  • Possible orbital period of the binary system, which favour a CV
