SWIFT J1753.5-0127 observed in XMM-Newton slew.
Abstract
The X-ray binary, SWIFT J1753.5-0127, discovered in outburst by the Swift BAT in 2005 (Palmer et al. 2005, ATel #546) was observed during an XMM- Newton slew on September 3rd 2009, with a 0.2-10 keV count rate of 118 c/s. Such bright sources suffer from heavy pile-up in the EPIC-pn camera during slews and the real count rate is estimated to be ~250 c/s. After excluding the inner 10" of the PSF and using single-pixel events only, to minimise pile-up effects, a spectral fit gives a 0.2-10 keV flux of 9.7+/-1.0E-10 ergs/s/cm^2 and a 2-10 keV flux of 6.6+/-0.9E-10 ergs/s/ cm^2.
