/* ** ** 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 56760.077325 0.000680 0.29711 0.02435 0.97872 0 9.26274 0.36222 5.76358 0.22460 2.75208 0.19817 1.72399 0.12351 56760.078728 0.000723 0.35034 0.02918 0.98400 0 8.23890 0.34991 4.60279 0.19545 2.88645 0.20677 1.61186 0.11548 56760.080250 0.000799 0.30280 0.02500 0.95290 0 8.82582 0.34697 4.90210 0.19265 2.67250 0.19406 1.49190 0.10830 56760.081813 0.000764 0.32462 0.02659 0.98864 0 8.61246 0.35057 4.75246 0.19328 2.79579 0.19875 1.53855 0.10931 56760.083425 0.000848 0.28017 0.02267 0.97611 0 8.96383 0.34053 4.95291 0.18812 2.51138 0.17939 1.39005 0.09926 56760.085080 0.000807 0.29804 0.02436 0.98566 0 8.87107 0.34884 4.83805 0.19024 2.64398 0.18947 1.44189 0.10330 56760.087047 0.001160 0.32081 0.02083 0.96509 0 9.14574 0.29074 5.11902 0.16270 2.93408 0.16610 1.64043 0.09283
