/* ** ** 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 56054.947250 0.000802 0.32662 0.02717 0.99639 0 5.06811 0.20991 4.37463 0.18118 1.65533 0.11940 1.42900 0.10307 56054.948981 0.000929 0.28227 0.02297 0.98131 0 5.16615 0.19589 4.46917 0.16947 1.45825 0.10498 1.26148 0.09081 56054.950786 0.000877 0.32073 0.02616 0.98680 0 4.83906 0.19680 4.17835 0.16993 1.55202 0.10975 1.34002 0.09475 56054.952708 0.001045 0.25650 0.02048 0.98061 0 5.09781 0.18429 4.38851 0.15865 1.30757 0.09307 1.12593 0.08014 56054.954531 0.000778 0.34262 0.02868 0.98141 0 5.03694 0.21178 4.34898 0.18285 1.72574 0.12489 1.49000 0.10782 56054.956805 0.001496 0.26776 0.01754 0.99420 0 5.05689 0.15296 4.37950 0.13247 1.35404 0.07868 1.17267 0.06814
