/* ** ** 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 54286.338594 0.000437 1.27433 0.06347 1.00000 0 11.16018 0.41833 10.13745 0.38004 14.22172 0.46650 12.91985 0.42381 54286.339445 0.000414 1.21336 0.05951 1.00000 0 12.38803 0.45557 11.33463 0.41683 15.03118 0.48776 13.75284 0.44628 54286.340290 0.000431 1.16660 0.05644 1.00000 0 12.36284 0.44320 11.30588 0.40531 14.42247 0.46847 13.18942 0.42842 54286.341143 0.000422 1.19055 0.05792 1.00000 0 12.42228 0.45074 11.31279 0.41046 14.78929 0.47929 13.47616 0.43668 54286.341985 0.000420 1.18636 0.05729 0.99310 0 12.66630 0.45639 11.58410 0.41739 15.02681 0.48312 13.74292 0.44185 54286.342796 0.000391 1.32626 0.06645 1.00000 0 12.08895 0.46296 11.05612 0.42341 16.03308 0.51790 14.66325 0.47365 54286.343620 0.000434 1.16169 0.05566 0.99333 0 12.49680 0.44261 11.42981 0.40482 14.51747 0.46852 13.27784 0.42851 54286.344436 0.000382 1.22924 0.05996 1.00000 0 13.29239 0.48538 12.15931 0.44400 16.33950 0.52839 14.94665 0.48335 54286.345272 0.000454 1.17230 0.05714 1.00000 0 11.63400 0.42031 10.64019 0.38441 13.63851 0.44623 12.47350 0.40811 54286.346155 0.000428 1.15160 0.05524 1.00000 0 12.75630 0.45265 11.61835 0.41226 14.69022 0.47409 13.38494 0.43194 54286.347026 0.000443 1.11350 0.05344 1.00000 0 12.57201 0.44132 11.49825 0.40362 13.99896 0.45822 12.80333 0.41909 54286.347894 0.000425 1.17552 0.05651 1.00000 0 12.56550 0.45011 11.49211 0.41166 14.77102 0.47349 13.50920 0.43304 54286.348748 0.000428 1.10918 0.05252 1.00000 0 13.17020 0.45663 12.04479 0.41761 14.60813 0.47101 13.35984 0.43077 54286.349601 0.000425 1.18895 0.05751 1.00000 0 12.42237 0.44927 11.36071 0.41088 14.76956 0.47434 13.50722 0.43380 54286.350472 0.000446 1.07048 0.05033 1.00000 0 13.20442 0.45004 11.98581 0.40844 14.13505 0.45773 12.82253 0.41522 54286.351334 0.000417 1.15628 0.05510 1.00000 0 13.09448 0.46175 11.93146 0.42074 15.14086 0.48537 13.79064 0.44206 54286.352179 0.000428 1.23194 0.06076 1.00000 0 11.84008 0.43912 10.78307 0.39992 14.58622 0.47425 13.28625 0.43196 54286.353024 0.000417 1.23405 0.06090 1.00000 0 12.12699 0.44923 11.03672 0.40882 14.96528 0.48794 13.62547 0.44429 54286.353855 0.000414 1.10393 0.05249 1.00000 0 13.74948 0.47941 12.47685 0.43498 15.17848 0.49069 13.77492 0.44528 54286.354908 0.000639 1.17241 0.04627 1.00000 0 12.44081 0.36430 11.34302 0.33213 14.58578 0.38590 13.29921 0.35183
