Very little known γ-ray source Simbad

Coordinates: RA 19h 29m 24.0s DEC +18° 16' 00"

Pulse period: 12.5 sec
Orbital period: 116-117 days, disputed

Spectrum: Swift/XRT and INTEGRAL/XRT describable with a feature less absorbed cutoff-powerlaw (PhoIndex = 0.4, N_H = 3.1e22, E_cut = 8keV) ^[1]; no indication for a CRSF

Bozzo et al. (2011)^[1] -- analysis of INTEGRAL and Swift data of an outburst in Oct 2010; confirmation of pulse, but no very significant signal for the orbital period, source most likely a Be system
Rodriguez et al. (2009)^[2] -- first paper after discovery, INTEGRAL, RXTE, and Swift, detection of pulse period and claimed 117 d orbital period
