/* ** ** 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 58312.143633 0.000566 1.10974 0.23184 0.92308 1 2.04351 0.31179 0.50072 0.07641 2.26776 0.32364 0.55674 0.07945 58312.144882 0.000683 0.88321 0.18042 0.93617 1 2.06191 0.29841 0.50469 0.07306 1.82109 0.26255 0.44642 0.06437 58312.146015 0.000450 0.92245 0.25648 1.00000 1 1.73340 0.36228 0.42628 0.08906 1.59897 0.29320 0.39232 0.07194 58312.147047 0.000581 1.18670 0.26123 0.87500 1 1.90782 0.31418 0.46680 0.07687 2.26401 0.33072 0.55441 0.08099 58312.148296 0.000668 1.20469 0.26728 0.84783 1 1.70181 0.28695 0.41897 0.07064 2.05016 0.29564 0.50366 0.07262 58312.149545 0.000581 1.59592 0.38298 0.95000 1 1.35156 0.26209 0.33367 0.06470 2.15698 0.30491 0.53214 0.07522 58312.151099 0.000973 1.47913 0.25670 0.95025 1 1.62954 0.22661 0.39855 0.05543 2.41030 0.25025 0.59031 0.06129 58312.276331 0.000156 1.09739 0.24729 0.98215 0 1.76840 0.29313 1.49321 0.24754 1.94062 0.29623 1.64352 0.25087 58312.276806 0.000305 1.08847 0.39427 1.00000 1 1.36535 0.38513 0.34523 0.09739 1.48615 0.33772 0.37528 0.08528 58312.278128 0.001017 0.97479 0.17346 0.93700 1 1.70155 0.22082 0.42980 0.05577 1.65865 0.20194 0.41963 0.05109
