4U 1820-30 1997 MayThis 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 #2289 (#1 in Galloway et al. 2008, ApJS 179, 360), of 4U 1820-303, observed on MJD 50570.73110 by the Rossi X-ray Timing Explorer (RXTE). Recurrence time 2.681±0.007 hr This event precedes the pair of bursts #1648 & 1649 observed by BeppoSAX; the recurrence time is derived from a linear fit to the times of these 3 events. The assumed cycle count is [0,19,20] Click here to download the data file 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 http://heasarc.gsfc.nasa.gov/docs/xte/recipes/pca_deadtime.html) and has the updated effective area of the v11.7 responses (see http://www.universe.nasa.gov/xrays/programs/rxte/pca/doc/rmf/pca-arf-2011 All uncertainties are at 1-sigma (68%) confidence. Note that the time value specifies the BEGINNING of the time bin For full details of the source sample see the MINBAR home page back to the reference burst table |
