/* ** ** 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 58323.105894 0.000538 0.18136 0.04416 0.98387 0 1.50299 0.14402 1.21724 0.11661 0.27258 0.06102 0.21894 0.04896 58323.106971 0.000538 0.16980 0.04014 0.96237 0 1.70653 0.15525 1.38415 0.12593 0.28976 0.06323 0.23503 0.05129 58323.108180 0.000671 0.12886 0.02990 0.96552 0 1.79528 0.14139 1.45744 0.11478 0.23135 0.05048 0.18781 0.04098 58323.109427 0.000576 0.13233 0.03153 0.97487 0 1.92183 0.15816 1.56093 0.12845 0.25431 0.05687 0.20653 0.04618 58323.110336 0.000333 0.22746 0.05725 0.97391 0 1.90879 0.20794 1.55213 0.16909 0.43418 0.09851 0.35312 0.08013 58323.111132 0.000463 0.17398 0.04222 0.93750 0 1.88743 0.17803 1.53500 0.14479 0.32837 0.07343 0.26711 0.05973 58323.111994 0.000399 0.19736 0.04854 0.98551 0 1.83835 0.18834 1.49365 0.15303 0.36281 0.08113 0.29461 0.06588 58323.112946 0.000553 0.12696 0.03066 0.97382 0 2.06298 0.17026 1.67514 0.13825 0.26192 0.05943 0.21263 0.04825 58323.114016 0.000518 0.14009 0.03347 0.95531 0 2.05861 0.17322 1.67234 0.14072 0.28840 0.06449 0.23431 0.05239 58323.115003 0.000469 0.16787 0.04063 0.96914 0 1.88457 0.17457 1.52112 0.14091 0.31636 0.07074 0.25520 0.05706 58323.116398 0.000926 0.17057 0.03047 0.98125 0 1.72494 0.11909 1.40212 0.09680 0.29422 0.04847 0.23915 0.03940
