/* ** ** 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 57087.902991 0.000596 0.38716 0.07536 0.90244 1 4.82988 0.48548 1.00578 0.10110 1.86995 0.31167 0.38919 0.06486 57087.903920 0.000334 0.31495 0.07988 0.95652 1 5.83588 0.73835 1.20550 0.15250 1.83801 0.40401 0.37923 0.08336 57087.904937 0.000683 0.42930 0.07367 0.95745 1 4.90536 0.46089 1.01973 0.09581 2.10585 0.30241 0.43812 0.06292 57087.905983 0.000363 0.34629 0.08907 0.88000 1 5.07537 0.64514 1.05007 0.13348 1.75753 0.39301 0.36364 0.08131 57087.907000 0.000654 0.38669 0.06486 1.00000 1 5.49984 0.49216 1.14550 0.10251 2.12672 0.30169 0.44318 0.06287 57087.908670 0.001017 0.45663 0.05986 0.93161 1 5.49008 0.39783 1.13451 0.08221 2.50696 0.27388 0.51788 0.05658
