/* ** ** 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 55626.539438 0.000457 0.29895 0.04850 0.98101 0 2.47497 0.19301 2.15084 0.16773 0.73990 0.10527 0.64282 0.09146 55626.540243 0.000347 0.35408 0.05874 0.97500 0 2.78370 0.23745 2.40767 0.20538 0.98565 0.14023 0.85160 0.12116 55626.541001 0.000411 0.32115 0.05148 0.96479 0 2.72364 0.21518 2.35730 0.18624 0.87470 0.12200 0.75652 0.10552 55626.541776 0.000365 0.33115 0.05394 0.96825 0 2.85290 0.23063 2.47896 0.20040 0.94474 0.13361 0.82104 0.11611 55626.542587 0.000446 0.25381 0.04046 0.96753 0 3.02639 0.21771 2.63369 0.18946 0.76814 0.10929 0.66870 0.09514 55626.543527 0.000495 0.23835 0.03768 0.96491 0 2.92513 0.20154 2.53225 0.17447 0.69721 0.09920 0.60386 0.08591 55626.544464 0.000443 0.25389 0.04042 0.96732 0 3.04634 0.21766 2.65110 0.18942 0.77344 0.11004 0.67322 0.09578 55626.545414 0.000506 0.23885 0.03820 0.97143 0 2.79361 0.19434 2.42738 0.16886 0.66725 0.09609 0.57986 0.08350 55626.546308 0.000388 0.29031 0.04679 0.99254 0 2.99139 0.23118 2.59076 0.20022 0.86842 0.12282 0.75313 0.10651 55626.547077 0.000382 0.41175 0.06236 0.96212 0 2.74051 0.22270 2.38245 0.19361 1.12841 0.14422 0.98126 0.12541 55626.547850 0.000391 0.29351 0.04672 0.97037 0 3.05646 0.23142 2.65724 0.20120 0.89710 0.12562 0.77992 0.10921 55626.548654 0.000414 0.31240 0.05105 0.97203 0 2.63865 0.21211 2.29584 0.18456 0.82431 0.11728 0.71681 0.10198 55626.549415 0.000347 0.33344 0.05493 0.98333 0 2.91504 0.24206 2.53313 0.21035 0.97199 0.13829 0.84438 0.12013 55626.550165 0.000402 0.30676 0.05008 0.98561 0 2.72958 0.21861 2.37172 0.18995 0.83732 0.11913 0.72728 0.10347 55626.550969 0.000402 0.25568 0.04048 0.97842 0 3.36253 0.24312 2.92367 0.21138 0.85972 0.12109 0.74735 0.10527 55626.551840 0.000469 0.25984 0.04200 0.96914 0 2.77602 0.20376 2.41617 0.17735 0.72133 0.10387 0.62788 0.09042 55626.553200 0.000891 0.27281 0.03139 0.95130 0 2.77983 0.14722 2.41893 0.12810 0.75837 0.07748 0.65960 0.06739
