/* ** ** 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 59649.516561 0.000579 0.28122 0.02286 0.98000 0 8.25691 0.31385 7.17623 0.27277 2.32197 0.16689 2.01775 0.14503 59649.517695 0.000556 0.30590 0.02510 0.97917 0 7.96713 0.31883 6.89904 0.27608 2.43712 0.17461 2.10913 0.15110 59649.518797 0.000547 0.28967 0.02395 0.98942 0 8.34796 0.32665 7.22383 0.28271 2.41818 0.17608 2.09267 0.15242 59649.519897 0.000553 0.28024 0.02286 0.98429 0 8.57304 0.32698 7.49104 0.28567 2.40249 0.17325 2.09810 0.15130 59649.520979 0.000530 0.33400 0.02789 0.98907 0 7.53732 0.31688 6.54781 0.27522 2.51750 0.18167 2.18457 0.15765 59649.522073 0.000564 0.30455 0.02460 0.97436 0 8.06513 0.31644 6.98595 0.27407 2.45621 0.17340 2.12440 0.14996 59649.523210 0.000573 0.28400 0.02326 1.00000 0 8.08792 0.31308 7.03229 0.27220 2.29694 0.16576 1.99701 0.14411 59649.524341 0.000558 0.27962 0.02265 0.99482 0 8.50952 0.32548 7.42735 0.28401 2.37946 0.16993 2.07060 0.14786 59649.525640 0.000741 0.26904 0.01920 0.98828 0 8.65868 0.28427 7.46955 0.24523 2.32954 0.14756 2.01040 0.12734
