/* ** ** 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 56946.998048 0.000480 1.46687 0.07609 1.00000 0 8.96942 0.36401 8.12565 0.32978 13.15700 0.42506 11.91641 0.38492 56946.999353 0.000825 1.59110 0.06388 0.99465 0 8.43455 0.26966 7.71157 0.24649 13.42017 0.32586 12.26782 0.29785 56947.002760 0.000436 1.72766 0.20165 0.99892 1 7.63664 0.71897 1.66520 0.15676 13.19350 0.91016 2.87450 0.19830 56947.004205 0.000498 1.38924 0.07142 0.99685 0 9.03572 0.35964 8.25536 0.32860 12.55276 0.40847 11.47178 0.37325 56947.005186 0.000483 1.54471 0.08205 1.00000 0 8.35002 0.35079 7.62012 0.32008 12.89838 0.41920 11.76409 0.38233 56947.006147 0.000477 1.54357 0.08278 1.00000 0 8.50647 0.36229 7.69379 0.32756 13.13030 0.42787 11.88442 0.38729 56947.007107 0.000483 1.53152 0.08164 1.00000 0 8.35606 0.35204 7.65618 0.32264 12.79746 0.41800 11.73210 0.38315 56947.008100 0.000509 1.50518 0.08082 1.00000 0 8.14546 0.34610 7.38320 0.31377 12.26038 0.40246 11.11414 0.36484 56947.009095 0.000486 1.47048 0.07746 1.00000 0 8.81478 0.36516 7.97036 0.33017 12.96195 0.42179 11.72089 0.38146 56947.010073 0.000492 1.35075 0.06940 1.00000 0 9.34483 0.36964 8.53917 0.33774 12.62254 0.41391 11.52997 0.37808 56947.011042 0.000477 1.37193 0.06992 1.00000 0 9.54323 0.37534 8.71573 0.34275 13.09262 0.42430 11.95424 0.38738 56947.012032 0.000512 1.43072 0.07456 1.00000 0 8.48082 0.34498 7.74814 0.31510 12.13370 0.39519 11.09002 0.36121 56947.013048 0.000503 1.38802 0.07145 0.98851 0 8.98819 0.35738 8.21117 0.32654 12.47583 0.40787 11.39202 0.37235 56947.014072 0.000521 1.31031 0.06647 1.00000 0 9.03710 0.35117 8.31479 0.32310 11.84137 0.38620 10.89498 0.35533 56947.015293 0.000700 1.40945 0.06085 0.99730 0 9.02286 0.30258 8.30280 0.27843 12.71726 0.34580 11.70250 0.31820 56947.065038 0.000480 1.78019 0.09849 0.99398 0 7.45480 0.33418 6.70148 0.30046 13.27093 0.43030 11.94166 0.38720 56947.066013 0.000495 1.56778 0.08582 1.00000 0 7.99473 0.34652 7.19945 0.31205 12.53395 0.41904 11.28687 0.37734 56947.067023 0.000515 1.49880 0.08105 1.00000 0 8.09721 0.34497 7.23854 0.30839 12.13613 0.40420 10.85059 0.36139 56947.068389 0.000851 1.55456 0.06322 1.00000 0 8.38170 0.27102 7.51139 0.24285 13.02981 0.32133 11.67480 0.28794
