/* ** ** 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 59775.599996 0.000686 0.23821 0.01900 0.99156 0 7.97245 0.27978 7.08048 0.24846 1.89909 0.13605 1.68731 0.12088 59775.601411 0.000729 0.23139 0.01852 0.99603 0 7.57803 0.26337 6.79142 0.23603 1.75348 0.12645 1.57148 0.11333 59775.602927 0.000787 0.22677 0.01796 0.98529 0 7.33899 0.25145 6.54383 0.22420 1.66429 0.11884 1.48341 0.10593 59775.604409 0.000694 0.22986 0.01845 0.99167 0 8.08644 0.28123 7.19549 0.25026 1.85874 0.13450 1.65296 0.11960 59775.605763 0.000660 0.25682 0.02050 0.98246 0 7.72786 0.27918 6.92872 0.25031 1.98466 0.14126 1.77943 0.12665 59775.607120 0.000697 0.25545 0.02021 0.97925 0 7.50106 0.26775 6.68717 0.23868 1.91615 0.13526 1.71032 0.12073 59775.609117 0.001299 0.23613 0.01404 0.98664 0 7.71502 0.19933 6.90001 0.17827 1.82175 0.09754 1.62904 0.08722
