/* ** ** 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 54304.341615 0.000450 2.60632 0.35037 1.00000 1 4.47902 0.51416 1.02093 0.11719 11.67377 0.81670 2.66203 0.18622 54304.342530 0.000465 2.44899 0.32779 1.00000 1 4.57424 0.51902 1.03185 0.11709 11.20225 0.79537 2.53056 0.17967 54304.343430 0.000436 2.01026 0.25256 1.00000 1 5.79889 0.59900 1.31692 0.13603 11.65730 0.83367 2.64614 0.18923 54304.344258 0.000392 2.16895 0.28146 1.00000 1 5.98077 0.64623 1.35336 0.14623 12.97199 0.93218 2.93491 0.21090 54304.345043 0.000392 2.68849 0.37348 1.00000 1 4.90674 0.58666 1.11738 0.13359 13.19174 0.93306 3.00192 0.21232 54304.345783 0.000349 3.09870 0.46600 1.00000 1 4.71562 0.62405 1.06628 0.14110 14.61232 1.04379 3.30230 0.23589 54304.346553 0.000421 2.25136 0.29871 1.00000 1 5.41025 0.60538 1.23144 0.13778 12.18043 0.86843 2.76709 0.19728 54304.347367 0.000392 3.12362 0.45724 1.00000 1 4.33558 0.55709 0.98389 0.12641 13.54270 0.94969 3.07326 0.21550 54304.348180 0.000421 2.65981 0.35837 0.99050 1 5.09320 0.59248 1.15432 0.13428 13.54694 0.92096 3.06977 0.20870 54304.406744 0.000378 2.61480 0.36087 1.00000 1 5.16338 0.60979 1.17552 0.13880 13.50121 0.96418 3.07338 0.21949 54304.407513 0.000392 2.18592 0.28899 1.00000 1 6.00418 0.66949 1.36350 0.15203 13.12467 0.93219 2.97467 0.21127 54304.408341 0.000436 2.14508 0.27497 1.00000 1 5.44351 0.58057 1.24993 0.13330 11.67673 0.83031 2.68147 0.19067 54304.409184 0.000407 2.82785 0.40149 1.00000 1 4.40547 0.54045 1.00459 0.12324 12.45803 0.89039 2.84443 0.20328 54304.409968 0.000378 2.77586 0.39227 1.00000 1 4.84543 0.59186 1.10608 0.13512 13.45022 0.95575 3.07138 0.21824 54304.411072 0.000726 2.78774 0.28163 0.99598 1 4.93975 0.43090 1.13158 0.09871 13.77077 0.70174 3.15300 0.16067 54304.473415 0.000378 2.97460 0.43703 1.00000 1 4.45427 0.57068 1.01766 0.13039 13.24968 0.95282 3.02952 0.21786 54304.474243 0.000450 2.99948 0.43949 1.00000 1 3.80293 0.48606 0.85681 0.10952 11.40681 0.81724 2.57704 0.18463 54304.475071 0.000378 2.72777 0.38978 1.00000 1 5.04217 0.62616 1.13483 0.14093 13.75388 0.97219 3.09452 0.21874 54304.475826 0.000378 3.36495 0.51305 1.00000 1 4.01227 0.54106 0.91387 0.12323 13.50108 0.96055 3.07609 0.21885 54304.476567 0.000363 2.82737 0.40002 1.00000 1 5.12064 0.62737 1.14910 0.14078 14.47797 1.02445 3.24944 0.22992 54304.477700 0.000770 2.62434 0.26989 0.98327 1 4.70931 0.41530 1.06450 0.09387 12.35884 0.65390 2.79025 0.14763
