GS 1826-24 1998 Jun

This profile forms part of the sample assembled for the paper "Thermonuclear burst observations for model comparisons: a reference catalogue" by Galloway, Goodwin & Keek (2017), to be submitted to PASA

This profile is from MINBAR burst #2393 (#7 in Galloway et al. 2008, ApJS 179, 360), of GS 1826-24, observed on MJD 50988.82504 by the Rossi X-ray Timing Explorer (RXTE).

Average recurrence time is 5.14±0.07 hr

The burst recurrence time is derived from a linear fit to the time of this burst and optical bursts observed at the same time; see Thompson et al. 2008, ApJ 681, 506 for details. The assumed cycle count is [0,1,5,6,10,11] The fit incorporates intrinsic variations in the recurrence time, arising (for example) from the variations in accretion rate over the bursting interval

The figure shows the results of time-resolved spectroscopic analysis. The estimated bolometric flux is plotted as green symbols & line, in units of 10-9 erg cm-2 s-1 (inner left-hand y-scale). The blackbody temperature kT is shown as purple symbols & line (right-hand y-axis, units of keV) and the normalisation as the aqua symbols & line (outermost left-hand y-scale, units of R2/d2, where R is the emitting radius in km, and d the distance to the source in units of 10 kpc).

This version of the data now includes deadtime correction (see and has the updated effective area of the v11.7 responses (see

All uncertainties are at 1-sigma (68%) confidence. Note that the time value specifies the BEGINNING of the time bin
