/* ** ** 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 59073.859216 0.000451 0.24310 0.03842 0.95513 0 3.26824 0.23057 2.76851 0.19532 0.79453 0.11237 0.67226 0.09507 59073.860023 0.000356 0.27718 0.04516 0.97561 0 3.49810 0.27170 2.97669 0.23119 0.96959 0.13885 0.82554 0.11823 59073.860816 0.000437 0.25092 0.03967 0.96026 0 3.27935 0.23533 2.79303 0.20043 0.82285 0.11593 0.70082 0.09874 59073.861800 0.000547 0.20263 0.03163 0.96296 0 3.17582 0.20386 2.70179 0.17343 0.64352 0.09158 0.54734 0.07789 59073.862743 0.000396 0.27649 0.04425 0.96350 0 3.22271 0.24152 2.74396 0.20565 0.89106 0.12602 0.75884 0.10732 59073.863524 0.000385 0.27927 0.04414 0.99353 0 3.34404 0.25165 2.84729 0.21426 0.93390 0.12981 0.79518 0.11053 59073.974414 0.000388 0.23697 0.03756 0.98507 0 3.75285 0.26254 3.18756 0.22299 0.88933 0.12647 0.75507 0.10738 59073.975143 0.000341 0.34190 0.05623 0.94915 0 3.07750 0.25426 2.60468 0.21521 1.05218 0.14964 0.88991 0.12656 59073.975814 0.000330 0.28141 0.04527 0.96491 0 3.79514 0.29105 3.23469 0.24807 1.06798 0.15104 0.91060 0.12878 59073.976543 0.000399 0.25918 0.04123 0.97101 0 3.38860 0.24683 2.88480 0.21013 0.87825 0.12420 0.74751 0.10571 59073.977706 0.000764 0.25011 0.03066 0.96591 0 3.15126 0.17478 2.68566 0.14896 0.78817 0.08615 0.67180 0.07343
