/* ** ** 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 55020.914859 0.000399 0.19783 0.03146 0.97101 0 4.34777 0.27648 3.67854 0.23392 0.86013 0.12538 0.72774 0.10608 55020.915580 0.000321 0.22833 0.03564 0.98198 0 4.82697 0.32455 4.08398 0.27459 1.10212 0.15524 0.93248 0.13134 55020.916338 0.000437 0.16702 0.02585 0.97351 0 4.77092 0.28121 4.03655 0.23793 0.79685 0.11406 0.67419 0.09650 55020.917362 0.000587 0.25967 0.02972 0.97796 0 4.48633 0.23258 3.79577 0.19678 1.16498 0.11888 0.98566 0.10058 55020.918268 0.000318 0.26250 0.04262 0.99091 0 4.07208 0.30545 3.44528 0.25843 1.06890 0.15393 0.90437 0.13023 55020.918910 0.000324 0.21681 0.03414 0.95538 0 5.19044 0.34079 4.41986 0.29020 1.12534 0.16108 0.95781 0.13709 55020.919547 0.000312 0.26330 0.04241 0.97222 0 4.15971 0.30597 3.58553 0.26373 1.09526 0.15694 0.94408 0.13527 55020.920163 0.000304 0.26401 0.04228 0.97143 0 4.33780 0.31864 3.70209 0.27195 1.14522 0.16295 0.97683 0.13898 55020.921005 0.000538 0.24361 0.02953 0.95712 0 4.65259 0.24706 3.93592 0.20900 1.13344 0.12351 0.95884 0.10448 55020.960969 0.000295 0.12524 0.02978 1.00000 0 5.55621 0.44990 3.13637 0.25396 0.69588 0.15560 0.39281 0.08784 55020.961799 0.000530 0.23495 0.03686 0.93989 0 4.39116 0.29820 2.47872 0.16833 1.03168 0.14590 0.58236 0.08236 55020.962803 0.000475 0.23466 0.03747 0.97561 0 4.65500 0.32263 2.62766 0.18212 1.09236 0.15714 0.61661 0.08870 55020.963746 0.000469 0.21853 0.03425 0.96296 0 5.17908 0.34121 2.92349 0.19261 1.13179 0.16097 0.63887 0.09086 55020.964646 0.000431 0.27905 0.04517 0.94631 0 4.44208 0.32971 2.50747 0.18611 1.23955 0.17832 0.69970 0.10066 55020.965520 0.000443 0.24846 0.04042 0.97386 0 4.67297 0.34005 2.63780 0.19195 1.16104 0.16895 0.65539 0.09537 55020.966458 0.000495 0.21886 0.03430 0.94737 0 4.97985 0.32800 2.81102 0.18515 1.08987 0.15501 0.61521 0.08750 55020.967337 0.000385 0.29967 0.04884 0.96992 0 4.54425 0.35511 2.56514 0.20046 1.36177 0.19478 0.76869 0.10995 55020.968171 0.000448 0.23465 0.03750 0.98065 0 4.90028 0.34090 2.76611 0.19243 1.14985 0.16541 0.64907 0.09337 55020.969102 0.000483 0.24880 0.03903 0.97006 0 4.49066 0.31747 2.53489 0.17921 1.11727 0.15645 0.63068 0.08831 55020.970187 0.000602 0.22428 0.03268 0.94712 0 4.71868 0.28899 2.66360 0.16313 1.05830 0.13991 0.59739 0.07898
