Landi et al. 2007 ATel 1273:
- A bright Swift source 4.3' from INTEGRAL source, suggested as
counterpart
- 1 USNO B1.0 source within Swift error box also 2MASS object, R~12.
- 2-10 keV flux = 1.5x10-13 erg/cm2/s
|
|
Tomsick et al. 2008:
- Chandra reveals 2 sources within INTEGRAL error box.
- Swift source outside INTEGRAL error box, detected with Chandra
- Since both Chandra and Swift sources are well outside INTEGRAL error, not clear if
they are related to IGR source
- If Swift source is not the counterpart: upper limit on the 0.3-10 keV source flux
4.1-4.5e-14 erg/s/cm2 assuming Γ=2.1

Malizia et al. 2010:
- XMM archival observation
- 1 source compatible with Chandra source
- 1 XMM SL source that appear to be transient, compatible with IBIS bursting catalogued source
=>XMM SL source favoured as the counterpart to IGR
- Source probable Galactic X-ray transient
