/* ** ** Swift/XRT hardness ratio for Mrk 501. ** 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 59564.125345 0.000625 0.28971 0.02365 0.98148 0 7.61518 0.29483 6.43455 0.24897 2.20617 0.15854 1.86563 0.13408 59564.126737 0.000767 0.23772 0.01917 0.98491 0 7.36783 0.25792 6.33733 0.22184 1.75151 0.12720 1.50725 0.10946 59564.128221 0.000718 0.25889 0.02078 0.99597 0 7.22533 0.26516 6.21577 0.22809 1.87054 0.13356 1.60961 0.11493 59564.129671 0.000732 0.24683 0.02000 0.98814 0 7.43387 0.26772 6.35520 0.22886 1.83494 0.13318 1.56968 0.11392 59564.131103 0.000700 0.25563 0.02060 0.98347 0 7.60625 0.27750 6.50319 0.23725 1.94438 0.13975 1.66182 0.11943 59564.132495 0.000692 0.26922 0.02182 0.98745 0 7.26748 0.27087 6.25345 0.23306 1.95654 0.14081 1.68414 0.12120 59564.134300 0.001114 0.27373 0.01742 0.97922 0 7.29105 0.21717 6.24159 0.18589 1.99575 0.11227 1.70787 0.09607
