Regarding the recent report on IGR J18175-1530 (Paizis et al., ATEL
#1248), this source was also detected RXTE PCA scans of the region.
At the time of the detection in September 2007, the source was
designated XTE J1817-155.
Based on analysis of PCA bulge scan data from around 02 Sep 2007,
the best fitting position was R.A. = 274.402, Dec = -15.508 (J2000),
with approximate 95% error radius of 10 arcminutes. This position is
consistent with the position reported by the INTEGRAL team.
The fluxes derived from the PCA bulge scans peak at about 6 mCrab
(2-10 keV) from 01-11 Sep 2007. After 24 Sep 2007, the source has
been undetectable, with typical 2 sigma upper limits of about 1.5
mCrab (2-10 keV).
