/* ** ** 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 59820.955998 0.001085 0.21252 0.01683 0.98133 0 5.55666 0.18398 5.05368 0.16732 1.18091 0.08494 1.07427 0.07726 59820.957407 0.000324 0.17483 0.02688 1.00000 0 5.59929 0.33807 5.11560 0.30887 0.97891 0.13844 0.89435 0.12648 59820.958058 0.000321 0.18514 0.02861 1.00000 0 5.33532 0.33213 4.87427 0.30343 0.98776 0.13969 0.90240 0.12762 59820.959449 0.001071 0.20842 0.01656 0.98108 0 5.70014 0.18943 5.21106 0.17318 1.18802 0.08573 1.08613 0.07838 59820.961539 0.001019 0.22839 0.01816 0.98295 0 5.48684 0.18890 5.01613 0.17269 1.25316 0.08982 1.14566 0.08211 59820.962875 0.000318 0.22524 0.03513 0.98182 0 4.63676 0.31429 4.23931 0.28735 1.04437 0.14672 0.95469 0.13413 59820.964256 0.001062 0.21221 0.01698 0.98365 0 5.59812 0.18785 5.11881 0.17176 1.18800 0.08632 1.08623 0.07892 59820.965636 0.000318 0.20663 0.03220 0.98182 0 4.90752 0.32124 4.48856 0.29382 1.01404 0.14341 0.92747 0.13116
