/* ** ** 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 59046.034173 0.000336 0.15952 0.03903 0.98276 0 2.55384 0.23201 2.16628 0.19679 0.40739 0.09254 0.34672 0.07873 59046.035004 0.000495 0.25738 0.04100 0.98830 0 2.72157 0.19960 2.30632 0.16913 0.70049 0.09907 0.59270 0.08382 59046.035892 0.000394 0.35166 0.05800 0.94853 0 2.58152 0.21532 2.20085 0.18356 0.90783 0.12917 0.77230 0.10989 59046.036881 0.000596 0.23981 0.03817 0.95631 0 2.48822 0.17325 2.09939 0.14615 0.59671 0.08541 0.50298 0.07201 59046.038143 0.000666 0.19456 0.03024 0.96957 0 2.74534 0.17182 2.29616 0.14370 0.53413 0.07600 0.44676 0.06357 59046.039361 0.000553 0.23363 0.03666 0.95812 0 2.78954 0.18966 2.33953 0.15906 0.65173 0.09217 0.54736 0.07741 59046.040568 0.000654 0.21075 0.03319 0.97345 0 2.54168 0.16668 2.14073 0.14039 0.53566 0.07669 0.45039 0.06448 59046.041769 0.000547 0.26461 0.04220 0.96825 0 2.45286 0.18076 2.06801 0.15240 0.64906 0.09180 0.54736 0.07741 59046.043366 0.001050 0.25276 0.02872 0.98347 0 2.56181 0.13163 2.16995 0.11148 0.64753 0.06562 0.54842 0.05557
