/* ** ** 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 55298.863314 0.000414 0.20706 0.03263 0.96503 0 4.33355 0.27790 3.47009 0.22240 0.89731 0.12914 0.71477 0.10285 55298.864038 0.000310 0.30267 0.04936 0.94393 0 4.01833 0.31461 3.23536 0.25330 1.21623 0.17399 0.98166 0.14044 55298.864695 0.000347 0.27533 0.04386 0.98333 0 3.83055 0.28517 3.13284 0.23322 1.05466 0.14852 0.86153 0.12132 55298.865493 0.000451 0.19680 0.03094 0.96795 0 4.11055 0.26029 3.32087 0.21027 0.80894 0.11639 0.65324 0.09399 55298.866387 0.000443 0.22644 0.03563 0.96078 0 3.70736 0.24954 2.99436 0.20154 0.83949 0.11941 0.67794 0.09643 55298.867163 0.000333 0.27605 0.04448 0.95652 0 4.01749 0.29780 3.26598 0.24208 1.10902 0.15865 0.90135 0.12895 55298.868592 0.001097 0.32350 0.02672 0.95778 0 4.15559 0.16786 3.36071 0.13574 1.34433 0.09686 1.08553 0.07821 55298.870079 0.000391 0.21294 0.03346 0.95556 0 4.46345 0.29010 3.61811 0.23515 0.95046 0.13596 0.76859 0.10995 55298.870855 0.000385 0.30701 0.04462 0.95489 0 4.02425 0.27912 3.19793 0.22180 1.23550 0.15780 0.98175 0.12540 55298.871599 0.000359 0.26545 0.04247 0.96774 0 3.93073 0.28787 3.12862 0.22912 1.04340 0.14841 0.83048 0.11812 55298.872293 0.000336 0.26759 0.04074 0.97414 0 4.61989 0.32494 3.67691 0.25861 1.23625 0.16691 0.98379 0.13282 55298.873028 0.000399 0.29056 0.04074 0.99275 0 4.19409 0.27961 3.37184 0.22478 1.21864 0.15031 0.97949 0.12081 55298.873803 0.000376 0.25853 0.04149 0.97692 0 3.75555 0.27302 3.01986 0.21955 0.97094 0.13893 0.78069 0.11169 55298.874512 0.000333 0.24194 0.03830 0.97391 0 4.62424 0.32140 3.67665 0.25554 1.11880 0.15913 0.88980 0.12656 55298.875247 0.000402 0.20569 0.03248 0.97842 0 4.43999 0.28883 3.52731 0.22946 0.91326 0.13141 0.72529 0.10436 55298.875950 0.000301 0.28895 0.04682 1.00000 0 4.16041 0.32101 3.34322 0.25792 1.20217 0.17129 0.96771 0.13783 55298.876659 0.000408 0.25539 0.03754 0.96454 0 4.20575 0.27775 3.35029 0.22124 1.07412 0.14104 0.85436 0.11218
