/* ** ** 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 53929.772673 0.000466 2.26983 0.13522 1.00000 0 5.89697 0.29356 5.36827 0.26724 13.38510 0.43796 12.18504 0.39869 53929.773730 0.000590 2.22256 0.11861 0.99876 0 5.85758 0.25997 5.33241 0.23666 13.01882 0.38575 11.85160 0.35116 53929.912075 0.000457 2.40786 0.14627 1.00000 0 5.71866 0.29448 5.21091 0.26834 13.76970 0.44375 12.54714 0.40435 53929.912998 0.000466 2.15469 0.12509 0.99379 0 6.26281 0.30132 5.70676 0.27457 13.49444 0.43843 12.29631 0.39950 53929.914005 0.000541 2.44646 0.13956 0.99819 0 5.49836 0.26661 5.01018 0.24294 13.45150 0.40426 12.25718 0.36837
