/* ** ** 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 58316.396735 0.000098 1.25447 0.23829 0.96544 0 3.52130 0.50304 3.16623 0.45232 4.41735 0.55304 3.97224 0.49731 58316.397245 0.000392 1.31018 0.28545 0.96296 1 2.48294 0.41275 0.60259 0.10018 3.25309 0.45815 0.78857 0.11106 58316.397956 0.000320 1.50352 0.34070 1.00000 1 2.63324 0.47216 0.64216 0.11512 3.95913 0.54856 0.96560 0.13377 58316.398639 0.000363 1.16477 0.25396 1.00000 1 2.84317 0.46866 0.69017 0.11377 3.31163 0.47263 0.80173 0.11441 58316.399380 0.000378 1.16850 0.25105 1.00000 1 2.72741 0.43694 0.65707 0.10527 3.18699 0.45623 0.76860 0.11004 58316.400121 0.000363 1.00814 0.21633 1.00000 1 3.23113 0.51217 0.78018 0.12367 3.25745 0.47116 0.78335 0.11331 58316.400832 0.000349 1.29981 0.29621 1.00000 1 2.66607 0.47557 0.64513 0.11508 3.46537 0.49146 0.84009 0.11913 58316.401617 0.000436 1.06223 0.21892 1.00000 1 2.77805 0.42392 0.66766 0.10188 2.95094 0.40878 0.70811 0.09810 58316.402430 0.000378 1.33871 0.30958 1.00000 1 2.34207 0.42342 0.56286 0.10177 3.13536 0.45211 0.75551 0.10893 58316.403186 0.000378 1.51399 0.35787 0.96154 1 2.16949 0.40635 0.51844 0.09711 3.28459 0.47361 0.78573 0.11329 58316.403970 0.000407 1.69928 0.40912 0.92857 1 1.88951 0.36640 0.45383 0.08799 3.21080 0.45821 0.77089 0.11001 58316.404711 0.000334 2.35333 0.60604 0.91304 1 1.72803 0.37255 0.41473 0.08940 4.06661 0.57279 0.97632 0.13750 58316.405989 0.000944 1.54382 0.20929 0.98514 1 2.53286 0.27309 0.61500 0.06630 3.91028 0.32135 0.94780 0.07789
