/* ** ** 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 58304.644086 0.000298 1.21614 0.05952 1.00000 0 17.31398 0.63346 15.73748 0.57579 21.05622 0.68454 19.13873 0.62220 58304.644682 0.000298 1.27841 0.06364 1.00000 0 16.77970 0.63531 14.99568 0.56777 21.45129 0.69335 19.18247 0.61989 58304.645278 0.000298 1.22128 0.05973 1.00000 0 17.28929 0.63432 15.72727 0.57701 21.11514 0.68299 19.20679 0.62127 58304.645882 0.000307 1.22965 0.06029 1.00000 0 16.80210 0.61756 15.19922 0.55864 20.66077 0.67051 18.69393 0.60659 58304.646499 0.000310 1.26576 0.06322 1.00000 0 15.88063 0.59720 14.45341 0.54353 20.10108 0.66062 18.29457 0.60125 58304.647141 0.000333 1.12626 0.05444 1.00000 0 16.65223 0.59298 15.15035 0.53950 18.75479 0.61314 17.06326 0.55784 58304.647763 0.000289 1.30919 0.06580 1.00000 0 16.54140 0.63253 14.96123 0.57192 21.65576 0.70633 19.59269 0.63899 58304.648354 0.000301 1.22246 0.05971 1.00000 0 17.23886 0.62943 15.51864 0.56663 21.07376 0.68379 18.96914 0.61546 58304.648950 0.000295 1.29542 0.06538 1.00000 0 16.53346 0.63649 14.88384 0.57283 21.41772 0.69898 19.27481 0.62901 58304.649531 0.000286 1.32939 0.06730 1.00000 0 16.62124 0.64400 14.90760 0.57752 22.09613 0.72001 19.83107 0.64608 58304.650127 0.000310 1.20947 0.05964 1.00000 0 16.93343 0.62725 15.20234 0.56320 20.48043 0.66656 18.38582 0.59836 58304.650744 0.000307 1.24204 0.06164 1.00000 0 16.77678 0.62937 14.92021 0.55976 20.83738 0.67691 18.53327 0.60214 58304.651337 0.000286 1.35881 0.06895 1.00000 0 16.42049 0.64041 14.70062 0.57325 22.31236 0.72429 19.97272 0.64829 58304.651913 0.000289 1.34520 0.06783 1.00000 0 16.54132 0.63650 14.62798 0.56288 22.25135 0.72522 19.67784 0.64135 58304.652520 0.000318 1.23948 0.06114 1.00000 0 16.06218 0.59741 14.53119 0.54037 19.90868 0.64497 17.98910 0.58274 58304.653142 0.000304 1.14678 0.05524 1.00000 0 18.11046 0.63931 16.26514 0.57423 20.76875 0.68079 18.65495 0.61142 58304.653741 0.000295 1.34690 0.06879 1.00000 0 15.83795 0.62142 14.23671 0.55863 21.33221 0.69752 19.17415 0.62693 58304.654329 0.000292 1.31265 0.06570 1.00000 0 16.74998 0.63787 14.84982 0.56557 21.98681 0.71420 19.49291 0.63312 58304.655069 0.000448 1.28152 0.05152 1.00000 0 16.95363 0.51745 15.20563 0.46400 21.72643 0.56849 19.47280 0.50954
