Miscellaneous :

Landi et al. 2012ATel 4165 :

Swift XRT observations
2 USNO B1.0 sources in Swift error box
Swift spectrum => N_H~2 x 10²² (compatible with Galactic value on line of sight) and Γ~1.3
Source probably galactic

Tomsick et al. 2014ATel 6793, Tomsick et al. 2016 (ApJ) :

Chandra ACIS observations
USNO B1.0 sources not in Chandra error
X-ray error of 0.4" by cross match with VISTA field sources
1 VISTA counterpart Z = 16.190, Y = 15.797, J = 15.240, H = 14.809,and Ks = 14.376,
Spitzer/GLIMPSE countepart m3.6 = 13.76, m4.5 = 13.15
Modest extinction, in X-rays N_H=6e21 cm-2 < Galactic value on line of sight => close source
Γ=0.3 + iron line @6.51 keV and width < 0.4, eq width 900 eV
Source is Galactic, probable CV or HMXB with the former possibility slightly favoured

Tomsick et al. 2016b (MNRAS) :

XMM and Nustar X-ray observations + optical spectroscopy with VLT and SOAR telescopes
XMM timing analysis => 576.3s period with pulse fraction 30% (0.3-12 keV)
Optical lines with significant variability => originate from irradiated accretion disk
Source classified as an intermediate polar CV.
Spectrum compatible with bremsstrahlung emission (kT 81 keV) with partial covering (N_H=1.4e23 cm-2 covering fraction 0.68) and reflection
Using the IP mass model the spectral analysis seems to indicate a high mass white dwarf (> 1.31 solar masses using only Nustar data)
