/* ** ** 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 53940.679095 0.000625 1.31350 0.20225 0.97674 1 3.13892 0.36885 0.74307 0.08732 4.12298 0.41025 0.97704 0.09722 53940.680054 0.000334 1.39210 0.31783 0.95652 1 2.69071 0.47566 0.64000 0.11314 3.74574 0.54117 0.89113 0.12874 53940.680707 0.000320 2.21949 0.57923 0.95455 1 1.85349 0.40737 0.43914 0.09652 4.11381 0.57890 0.97704 0.13749 53940.681492 0.000465 1.29191 0.27461 0.90625 1 2.27258 0.35919 0.53663 0.08481 2.93597 0.41729 0.69372 0.09860 53940.682262 0.000305 2.28513 0.60480 1.00000 1 1.82938 0.41101 0.43022 0.09666 4.18037 0.58483 0.98242 0.13743 53940.682886 0.000320 2.47220 0.68654 1.00000 1 1.58603 0.38035 0.37460 0.08984 3.92098 0.54906 0.92728 0.12984 53940.683787 0.000552 1.57467 0.27009 0.97368 1 2.56788 0.34306 0.60620 0.08099 4.04355 0.43498 0.95467 0.10270 53940.685356 0.001017 2.06736 0.26210 0.98571 1 2.35653 0.24686 0.55621 0.05827 4.87181 0.34790 1.14879 0.08204 53940.686924 0.000552 1.67966 0.30728 0.92217 1 2.44992 0.35997 0.57855 0.08500 4.11504 0.44850 0.97200 0.10593
