/* ** ** 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 57105.454393 0.000631 0.32483 0.02695 0.98165 0 6.28913 0.25654 5.66315 0.23097 2.04293 0.14762 1.84003 0.13295 57105.455716 0.000692 0.28411 0.02280 0.98326 0 6.71876 0.25334 6.04917 0.22809 1.90889 0.13521 1.71795 0.12168 57105.457093 0.000686 0.29086 0.02406 0.99578 0 6.28743 0.24560 5.69146 0.22232 1.82879 0.13337 1.65597 0.12077 57105.458415 0.000637 0.31730 0.02604 0.99545 0 6.33965 0.25668 5.73730 0.23229 2.01158 0.14363 1.82067 0.13000 57105.459680 0.000628 0.33601 0.02787 0.97696 0 6.12747 0.25210 5.54700 0.22821 2.05889 0.14830 1.86203 0.13412 57105.461378 0.001071 0.32363 0.02084 0.99067 0 6.01267 0.19258 5.43813 0.17419 1.94589 0.10869 1.75995 0.09830 57105.463061 0.000596 0.38318 0.06400 0.97561 1 5.08410 0.44807 1.29948 0.11452 1.94811 0.27641 0.49849 0.07073 57105.464804 0.001148 0.39693 0.04928 0.96652 1 4.70459 0.31037 1.20258 0.07933 1.86742 0.19641 0.47802 0.05028
