/* ** ** 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 55785.170602 0.000370 2.42272 0.14836 1.00000 0 7.52962 0.39090 6.34725 0.32948 18.24219 0.59251 15.38519 0.49960 55785.171345 0.000373 2.50406 0.15307 1.00000 0 7.19409 0.37315 6.09776 0.31625 18.01443 0.58268 15.28141 0.49422 55785.172115 0.000396 2.22693 0.13207 1.00000 0 7.46425 0.37048 6.46130 0.32070 16.62234 0.53950 14.38910 0.46701 55785.172905 0.000394 2.29256 0.13543 1.00000 0 7.46081 0.36957 6.36293 0.31513 17.10433 0.55049 14.57438 0.46903 55785.173675 0.000376 2.43331 0.14897 1.00000 0 7.28565 0.37926 6.27315 0.32656 17.72822 0.57126 15.25323 0.49147 55785.174444 0.000394 2.50183 0.15453 1.00000 0 6.86794 0.36084 5.79786 0.30461 17.18243 0.55806 14.51555 0.47143 55785.175237 0.000399 2.41460 0.14640 0.99275 0 7.05535 0.36135 5.94874 0.30468 17.03582 0.55284 14.35399 0.46580 55785.176076 0.000440 2.42703 0.14103 0.99581 0 6.89625 0.33889 5.84185 0.28702 16.73739 0.51910 14.16720 0.43938
