/* ** ** Swift/XRT hardness ratio for 4U 1608-52. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 58318.321942 0.000113 1.36069 0.34278 0.97697 0 1.90805 0.37950 1.64150 0.32648 2.59627 0.40138 2.23342 0.34529 58318.322549 0.000479 1.52444 0.37644 1.00000 1 1.51680 0.30036 0.38298 0.07583 2.31228 0.34113 0.58260 0.08596 58318.323435 0.000407 1.25378 0.27264 1.00000 1 2.31562 0.38704 0.59133 0.09883 2.90328 0.40385 0.74074 0.10304 58318.324263 0.000421 2.29301 0.61761 0.96552 1 1.21616 0.27809 0.30933 0.07072 2.78867 0.39692 0.71004 0.10106 58318.325120 0.000436 1.60540 0.39216 0.96667 1 1.70646 0.34050 0.43511 0.08682 2.73956 0.38603 0.69935 0.09855 58318.325948 0.000392 1.58981 0.39115 1.00000 1 1.81624 0.36390 0.46106 0.09239 2.88747 0.41231 0.73413 0.10483 58318.326747 0.000407 1.63443 0.38109 0.92857 1 1.87588 0.34846 0.47791 0.08876 3.06600 0.43206 0.78004 0.10992 58318.327633 0.000479 1.45095 0.33216 0.93939 1 1.76604 0.31627 0.45048 0.08066 2.56242 0.36542 0.65368 0.09323 58318.328591 0.000479 1.21972 0.26165 0.96970 1 2.02207 0.32467 0.51559 0.08278 2.46636 0.35085 0.62820 0.08937 58318.329550 0.000450 1.47672 0.34273 0.96774 1 1.74642 0.31827 0.44438 0.08098 2.57897 0.37064 0.65674 0.09439 58318.330552 0.000552 1.16712 0.25427 0.92105 1 1.87497 0.30463 0.47892 0.07782 2.18832 0.31762 0.55782 0.08096 58318.331598 0.000494 1.18696 0.25394 0.94118 1 2.18681 0.35571 0.55654 0.09053 2.59565 0.36069 0.66197 0.09199 58318.332571 0.000479 1.05027 0.22873 1.00000 1 2.27496 0.37266 0.58094 0.09517 2.38931 0.34289 0.61045 0.08761 58318.333864 0.000813 1.82215 0.32944 0.97861 1 1.55187 0.23152 0.39220 0.05851 2.82775 0.28880 0.71577 0.07310
