/* ** ** 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 54294.098623 0.001002 1.94686 0.24645 0.95652 1 2.48421 0.25808 0.60963 0.06332 4.83639 0.34985 1.18684 0.08584 54294.100845 0.001220 1.70709 0.19261 0.97423 1 2.76422 0.25378 0.67847 0.06229 4.71878 0.30950 1.15829 0.07597 54294.241537 0.001496 2.14151 0.24447 0.99892 1 2.09522 0.20341 0.51464 0.04996 4.48693 0.26946 1.10216 0.06618 54294.314163 0.000930 1.91096 0.24480 0.98438 1 2.70093 0.28636 0.65664 0.06960 5.16136 0.37109 1.25358 0.09013 54294.350046 0.034954 1.78871 0.19043 0.03777 1 2.81115 0.24524 0.67400 0.05879 5.02833 0.30684 1.20401 0.07346 54294.385886 0.000886 2.08705 0.27556 0.96721 1 2.74883 0.30434 0.64107 0.07098 5.73695 0.41269 1.33802 0.09624 54294.387644 0.000872 1.89822 0.24554 0.98333 1 3.03230 0.32688 0.70755 0.07626 5.75596 0.41151 1.34211 0.09595 54294.390433 0.001917 1.69382 0.15086 0.98986 1 2.88728 0.20786 0.67660 0.04870 4.89052 0.25646 1.14613 0.06010 54294.447454 0.000901 2.12238 0.28406 1.00000 1 2.39054 0.26975 0.59962 0.06765 5.07363 0.36516 1.26931 0.09135 54294.449284 0.000930 1.66924 0.21230 1.00000 1 2.94569 0.30915 0.73935 0.07758 4.91706 0.35326 1.23497 0.08872 54294.451085 0.000872 2.07429 0.27495 1.00000 1 2.51032 0.27904 0.63075 0.07010 5.20713 0.37599 1.30767 0.09442 54294.452930 0.000973 1.61314 0.19105 1.00000 1 2.91440 0.27491 0.73382 0.06923 4.70133 0.33666 1.18321 0.08473 54294.455748 0.001845 1.71722 0.14972 0.99177 1 2.87868 0.20320 0.72076 0.05087 4.94333 0.25299 1.23644 0.06328
