| Miscellaneous :
|
| B~19. Possible IR counterpart |
|
Masetti et al. (2006) :
- Halpha, EW=5.5 Angstrom
- R=14.3
|
|
Tomsick et al. (2008) :
- Chandra position confirms all proposed associations
- Absorbed power law, NH=1.9x1022 cm-2,
Γ= 0.8, Unabs. 0.3-10 keV flux=26 e-12 erg/cm2/s
- Absorption not necessarily local, although slightly higher than
Galactic value

Nichelli et al. (2011) ATel 3205:
- Coherent X-ray pulsations detected by Swift-XRT at a period of
328.182(3) s
- P_dot = 1.5e-8 s/s
- Periodicity detected in the 18-30 keV band in archival INTEGRAL-ISGRI
observations from 2003 to 2006
- Confirms that IGR J17200-3116 = accreting pulsar / HMXB

Esposito et al. 2014 (A&A):
- Analysis of 2005-2011 Swift data and a 20 ks XMM osbervation (Sept. 2013)
- Strong pulse to pulse variations and pulse profile energy dependence evident => pulsar in massive binary confirmed
- Variation of NH by up to a factor of 4
- Dip in XMM light curve characterized by a softening of emission => probable transition to a different accretion regime
