/* ** ** 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 53932.993682 0.000124 2.25136 0.29106 1.00000 0 4.58084 0.49328 4.12711 0.44443 10.31312 0.73786 9.26554 0.66297 53932.994018 0.000211 2.62690 0.27756 0.98630 0 4.13651 0.37692 3.76719 0.34326 10.86621 0.58119 9.89042 0.52902 53932.994351 0.000122 2.47707 0.33581 1.00000 0 4.20337 0.48408 3.85412 0.44381 10.41203 0.74473 9.54781 0.68294 53932.994591 0.000119 2.56426 0.35902 1.00000 0 4.17212 0.50122 3.77393 0.45351 10.69842 0.76923 9.68296 0.69617 53932.994854 0.000145 2.15027 0.27653 1.00000 0 4.12006 0.44223 3.78031 0.40577 8.85921 0.62751 8.12863 0.57576 53932.995132 0.000133 1.99328 0.25265 1.00000 0 4.83305 0.50518 4.37868 0.45757 9.63364 0.69066 8.73032 0.62583 53932.995401 0.000136 1.99540 0.25339 1.00000 0 4.64400 0.48621 4.26096 0.44610 9.26666 0.66599 8.50194 0.61103 53932.995679 0.000142 1.82497 0.22963 1.00000 0 4.81843 0.49413 4.42100 0.45337 8.79347 0.64110 8.06818 0.58822 53932.995942 0.000122 2.78848 0.41524 1.00000 0 3.67582 0.47898 3.37271 0.43948 10.24993 0.73885 9.40471 0.67792 53932.996278 0.000214 2.09998 0.21283 0.98823 0 4.60720 0.38835 4.22723 0.35632 9.67503 0.54442 8.87711 0.49952
