J/ApJS/179/360   Thermonuclear X-ray bursts observed by RXTE   (Galloway+, 2008)

Thermonuclear (type-I) X-ray bursts observed by the Rossi X-ray Timing Explorer. Galloway D.K., Muno M.P., Hartman J.M., Psaltis D., Chakrabarty D. <Astrophys. J. Suppl. Ser. 179, 360 (2008)> =2008ApJS..179..360G
ADC_Keywords: X-ray sources Keywords: nuclear reactions, nucleosynthesis, abundances - stars: distances - stars: neutron - X-rays: bursts Description: We present a sample of 1187 thermonuclear (type-I) X-ray bursts from public (archival) observations of 48 low-mass X-ray binaries accreting neutron stars by the Rossi X-ray Timing Explorer, spanning 1996 January - 2007 June 3. For each burst, we list results of analysis of data from the Proportional Counter Array, including observed count rates, time-resolved spectroscopy, evolution of the burst lightcurve, and details of the persistent flux and source spectral state at the time of the burst.

Note (1): Flag as follows: a = The burst was observed during a slew, and thus offset from the source position b = The observation was offset from the source position. In cases (a) and (b) we scaled the flux and fluence by the mean collimator response appropriate for the position of the source in the field of view, as described in appendix B c = The origin of the burst is uncertain; the burst may have been from another source in the field-of-view (we rescaled the flux and fluence, if necessary, based upon the assumed origin) d = Buffer overruns (or some other instrumental effect) caused gaps in the high time-resolution data e = The burst was so faint that only the peak flux could be measured, and not the fluence or other parameters f = An extremely faint burst or possibly problems with the background subtraction, resulting in no fit results g = The full burst profile was not observed, so that the event can be considered an unconfirmed burst candidate. Typically in these cases the initial burst rise is missed, so that the measured peak flux and fluence are lower limits only h = High-time resolution datamodes did not cover the burst. Note (2): We neglect corrections to give the time at the solar-system barycenter. Note (3): In units of 10-9erg/s/cm-2. Note (4): The hard and soft X-ray colors are the ratios of the background-subtracted PCA counts in the (8.6-18.0)/(5.0-8.6)keV and (3.6-5.0)/(2.2-3.6)keV energy bands, respectively, calculated from 64s integrations when the source intensity was above 100ct/s, and 256s integrations otherwise, and corrected for gain variations over the mission lifetime by comparison to the colors of the Crab nebula Note (5): In units of 10-6erg/cm2. Note (6): Presence of radius expansion flag as follows: Y = yes N = no Y? = possible blank = unknown Note (7): Normalized by the mean peak flux of the PRE bursts FEdd, where available (Ub in van Paradijs et al., 1988MNRAS.233..437V).
