/* ** ** 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 58338.045674 0.000284 1.74864 0.21150 0.97959 0 2.63057 0.25564 2.35754 0.22908 4.59992 0.33124 4.12333 0.29692 58338.046305 0.000347 1.20394 0.13248 1.00000 0 3.07737 0.25506 2.71860 0.22544 3.70496 0.26820 3.27486 0.23706 58338.046987 0.000336 1.32499 0.14795 0.99138 0 2.94750 0.25195 2.62642 0.22448 3.90540 0.28059 3.47950 0.24992 58338.048032 0.000709 1.43842 0.12436 0.80915 0 2.74552 0.18552 2.46123 0.16631 3.94921 0.21300 3.54009 0.19094 58338.049264 0.000508 1.38326 0.28339 0.68601 1 2.90044 0.45807 0.71456 0.11284 4.01205 0.52356 0.98964 0.12914 58338.050194 0.000421 1.39669 0.26695 0.96552 1 2.81198 0.41418 0.69786 0.10278 3.92747 0.47841 0.97507 0.11876 58338.050935 0.000320 1.44289 0.34101 0.95455 1 2.66636 0.50219 0.65908 0.12413 3.84728 0.54924 0.95440 0.13621 58338.051574 0.000320 1.46130 0.35142 1.00000 1 2.39994 0.45572 0.59798 0.11355 3.50704 0.51749 0.87386 0.12894 58338.052547 0.000654 1.57843 0.24639 1.00000 1 2.51095 0.30959 0.62285 0.07680 3.96336 0.37942 0.98364 0.09416 58338.053607 0.000407 1.24517 0.26350 0.96429 1 2.44785 0.38657 0.60898 0.09616 3.04799 0.42934 0.75933 0.10695 58338.054319 0.000305 1.77143 0.44891 1.00000 1 2.14214 0.44847 0.53237 0.11146 3.79465 0.54186 0.94387 0.13478 58338.055045 0.000421 1.20255 0.25328 0.96552 1 2.45034 0.38074 0.60364 0.09380 2.94665 0.41898 0.72582 0.10319 58338.055772 0.000305 1.59633 0.38048 1.00000 1 2.45849 0.47273 0.61229 0.11773 3.92457 0.55274 0.97628 0.13750 58338.056701 0.000625 1.19420 0.18491 0.99263 1 3.22378 0.38042 0.79470 0.09376 3.84984 0.38593 0.94989 0.09522
