/* ** ** 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 59439.958375 0.000417 0.24348 0.03886 0.98611 0 3.37744 0.23865 2.86578 0.20249 0.82236 0.11770 0.69794 0.09990 59439.959200 0.000408 0.24061 0.03858 0.97163 0 3.49169 0.24620 2.99096 0.21089 0.84015 0.12100 0.71954 0.10362 59439.959947 0.000339 0.27441 0.04369 0.99145 0 3.76931 0.27984 3.19511 0.23721 1.03434 0.14568 0.87621 0.12342 59439.960606 0.000321 0.32375 0.05301 0.95495 0 3.36583 0.27271 2.90413 0.23530 1.08968 0.15503 0.93997 0.13373 59439.961312 0.000385 0.29294 0.04764 0.97744 0 3.01665 0.23301 2.60344 0.20109 0.88370 0.12649 0.76236 0.10912 59439.962068 0.000370 0.30570 0.04964 0.94531 0 3.14089 0.24581 2.70180 0.21146 0.96018 0.13661 0.82344 0.11715 59439.962817 0.000379 0.24993 0.03963 0.98473 0 3.62411 0.26000 3.10770 0.22294 0.90577 0.12810 0.77649 0.10981 59439.963873 0.000677 0.25851 0.03115 0.96792 0 3.48453 0.19022 3.00892 0.16426 0.90078 0.09678 0.77785 0.08357
