/* ** ** 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 54315.733984 0.000064 1.98413 0.30657 0.95556 0 6.84633 0.86256 6.00363 0.75639 13.58399 1.21499 11.91196 1.06544 54315.794286 0.000501 2.15548 0.12851 1.00000 0 7.63034 0.37758 5.23395 0.25897 16.44702 0.54695 11.28201 0.37499 54315.795290 0.000503 2.35137 0.14448 1.00000 0 7.17990 0.37395 4.81671 0.25055 16.88263 0.55041 11.32874 0.36925 54315.796292 0.000498 2.39770 0.14583 1.00000 0 7.03113 0.36010 4.76831 0.24429 16.85856 0.55306 11.41897 0.37469 54315.797290 0.000501 2.07495 0.12301 1.00000 0 8.01567 0.39300 5.43112 0.26619 16.63212 0.55426 11.27296 0.37573 54315.798300 0.000509 2.22271 0.13446 1.00000 0 7.38470 0.37880 5.07826 0.26050 16.41406 0.52639 11.29003 0.36205 54315.799307 0.000498 2.13592 0.12415 1.00000 0 7.98241 0.38658 5.41744 0.26235 17.04975 0.54802 11.55513 0.37141 54315.800175 0.000370 2.73578 0.17444 1.00000 0 8.48283 0.46722 5.70282 0.31399 23.20719 0.74551 15.62453 0.50182 54315.800603 0.000058 6.98760 0.39860 0.99159 0 57.26401 3.06819 39.31176 2.10633 400.13818 7.83287 274.66458 5.37669
