/* ** ** 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 54296.038895 0.000770 1.97980 0.25002 0.98113 1 3.10640 0.32267 0.76502 0.07946 6.15003 0.44171 1.51634 0.10890 54296.040551 0.000886 1.74109 0.21491 1.00000 1 3.00712 0.30127 0.74672 0.07479 5.23567 0.37752 1.29814 0.09360 54296.042585 0.001148 1.88041 0.21216 0.98471 1 2.74436 0.25540 0.68349 0.06361 5.16053 0.32919 1.28607 0.08204 54296.106253 0.000915 1.86813 0.23095 0.98413 1 2.77658 0.27926 0.68403 0.06880 5.18701 0.37287 1.27751 0.09183 54296.108025 0.000857 1.92758 0.25284 0.98305 1 2.82338 0.30887 0.69965 0.07653 5.44229 0.39388 1.34978 0.09769 54296.109710 0.000828 1.73229 0.21237 1.00000 1 3.25815 0.32388 0.80628 0.08014 5.64407 0.40497 1.39946 0.10040 54296.111308 0.000770 1.95873 0.25295 1.00000 1 3.04048 0.32565 0.75626 0.08100 5.95548 0.42968 1.48158 0.10688 54296.113327 0.001249 2.15407 0.23083 0.97277 1 2.68085 0.24085 0.66013 0.05931 5.77473 0.33731 1.42155 0.08303 54296.172759 0.000842 1.95545 0.25048 1.00000 1 2.91890 0.31180 0.71770 0.07665 5.70774 0.40349 1.40162 0.09908 54296.174487 0.000886 2.12936 0.28520 1.00000 1 2.47470 0.27952 0.61008 0.06891 5.26953 0.37928 1.29691 0.09334 54296.176288 0.000915 2.00660 0.25629 0.96825 1 2.61691 0.27636 0.64487 0.06810 5.25111 0.37723 1.29239 0.09283 54296.178060 0.000857 1.74367 0.21973 1.00000 1 3.14665 0.32637 0.77322 0.08020 5.48672 0.39271 1.34778 0.09647 54296.179702 0.000784 1.89083 0.24775 1.00000 1 3.13811 0.34327 0.76945 0.08415 5.93364 0.42797 1.45453 0.10490 54296.181329 0.000842 2.00636 0.26204 1.00000 1 2.77340 0.30243 0.67858 0.07400 5.56443 0.39995 1.36212 0.09790 54296.182941 0.000770 2.01389 0.26519 1.00000 1 2.96289 0.32507 0.72912 0.07999 5.96694 0.43447 1.46879 0.10694 54296.184902 0.001191 2.51114 0.27812 0.99045 1 2.52922 0.24093 0.62347 0.05938 6.35123 0.35883 1.56580 0.08846
