/* ** ** 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 57122.958635 0.000686 0.33688 0.02801 0.97046 0 5.79001 0.24009 5.09112 0.21107 1.95052 0.14060 1.71536 0.12366 57122.960290 0.000969 0.29603 0.02235 0.98454 0 5.41020 0.19707 4.76787 0.17365 1.60157 0.10591 1.41189 0.09337 57122.961816 0.000537 0.50516 0.08782 0.97297 1 4.46601 0.44617 1.09355 0.10925 2.25607 0.32100 0.55242 0.07860 57122.962658 0.000305 0.32842 0.08883 1.00000 1 4.56999 0.63251 1.11901 0.15488 1.50087 0.34876 0.36750 0.08540 57122.963631 0.000668 0.36790 0.06109 0.93478 1 5.11942 0.43453 1.25354 0.10640 1.88343 0.26880 0.46118 0.06582 57122.964939 0.000639 0.38251 0.06505 0.97727 1 4.86783 0.43680 1.19193 0.10696 1.86197 0.26901 0.45592 0.06587 57122.966202 0.000625 0.38800 0.06388 0.93023 1 5.36811 0.46496 1.31443 0.11385 2.08284 0.29166 0.51000 0.07141 57122.968134 0.001307 0.37399 0.04552 0.95838 1 4.73938 0.29774 1.16048 0.07290 1.77249 0.18479 0.43401 0.04525
