/* ** ** 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 58676.670686 0.000339 0.18644 0.04556 0.99145 0 2.19797 0.21666 1.85499 0.18285 0.40978 0.09164 0.34540 0.07723 58676.671392 0.000362 0.18096 0.04406 0.97600 0 2.14889 0.20688 1.81220 0.17447 0.38887 0.08696 0.32842 0.07344 58676.672159 0.000405 0.16147 0.03898 0.99286 0 2.12352 0.19295 1.78662 0.16232 0.34289 0.07668 0.28825 0.06445 58676.673073 0.000509 0.12348 0.02936 0.97727 0 2.24963 0.18158 1.89225 0.15272 0.27779 0.06212 0.23295 0.05209 58676.673927 0.000344 0.18235 0.04193 0.97479 0 2.54261 0.23029 2.15371 0.19506 0.46365 0.09800 0.39249 0.08296 58676.674685 0.000414 0.14910 0.03584 0.99301 0 2.23245 0.19709 1.89241 0.16707 0.33285 0.07443 0.28216 0.06309 58676.675437 0.000339 0.16222 0.04098 1.00000 0 2.38769 0.22447 2.02424 0.19030 0.38733 0.09082 0.32840 0.07700 58676.676271 0.000495 0.13976 0.03388 0.97661 0 2.00231 0.16951 1.69031 0.14310 0.27984 0.06356 0.23664 0.05375 58676.677428 0.000663 0.23597 0.03719 0.98253 0 2.25176 0.15502 1.90372 0.13104 0.53135 0.07532 0.44922 0.06368 58676.678577 0.000486 0.12692 0.03016 0.98810 0 2.24294 0.18021 1.90174 0.15280 0.28467 0.06365 0.24137 0.05397 58676.679795 0.000732 0.14580 0.02783 0.95652 0 2.12481 0.14365 1.80137 0.12178 0.30979 0.05530 0.26264 0.04688
