Miscellaneous :
Levine et al. Atel 623: RXTE/ASM Hardness ratios are very soft => suggests black hole binary with thermal spectrum

  • NH=4.8 x1021 cm-2
  • kT=0.91 keV for a model of bremsstrahlung.
  • Comparing this observation with previous drop in flux of about 60%.
  • A disk blackbody model also represents the data well with kT= 0.53 keV
