/* ** ** 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 57234.850254 0.000321 0.16770 0.02605 1.00000 0 6.07530 0.35584 5.36484 0.31416 1.01880 0.14658 0.90113 0.12961 57234.850882 0.000307 0.18316 0.02928 0.97170 0 5.78862 0.35857 5.12562 0.31747 1.06025 0.15622 0.94126 0.13871 57234.851501 0.000312 0.20051 0.03126 0.97222 0 5.50169 0.34893 4.85048 0.30758 1.10314 0.15708 0.97170 0.13834 57234.852864 0.001050 0.22798 0.01824 0.96419 0 5.55090 0.18849 4.92611 0.16725 1.26552 0.09166 1.12332 0.08135 57234.854233 0.000318 0.19035 0.03062 1.00000 0 5.25651 0.33814 4.63081 0.29787 1.00057 0.14753 0.88136 0.12988 57234.855572 0.001021 0.24672 0.01992 0.97450 0 5.24429 0.18712 4.63771 0.16547 1.29387 0.09370 1.14291 0.08277 57234.856938 0.000344 0.19123 0.02956 0.97479 0 5.11760 0.31909 4.51551 0.28150 0.97866 0.13841 0.86351 0.12212 57234.858000 0.000718 0.20699 0.02131 0.97177 0 5.31769 0.22401 4.71344 0.19855 1.10068 0.10337 0.97526 0.09160 57234.859904 0.001186 0.25629 0.01853 0.97805 0 5.32525 0.17479 4.74444 0.15573 1.36480 0.08792 1.21596 0.07833
