/* ** ** Swift/XRT hardness ratio for Mrk 421. ** 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 55894.040368 0.000475 0.13146 0.01978 0.97561 0 5.60709 0.28693 4.76154 0.24361 0.73713 0.10428 0.62604 0.08854 55894.041349 0.000506 0.11268 0.01724 0.97143 0 5.97637 0.28712 5.13124 0.24649 0.67339 0.09780 0.57695 0.08378 55894.042330 0.000475 0.13027 0.01964 1.00000 0 5.48305 0.28610 4.69516 0.24494 0.71427 0.10102 0.61077 0.08638 55894.043238 0.000434 0.13590 0.02052 0.98667 0 5.90057 0.31169 4.97859 0.26300 0.80187 0.11340 0.67680 0.09571 55894.044069 0.000396 0.14598 0.02239 0.97810 0 5.96850 0.32567 5.06558 0.27639 0.87129 0.12487 0.73973 0.10600 55894.044983 0.000518 0.10745 0.01600 0.98324 0 6.28281 0.29254 5.30054 0.24679 0.67509 0.09547 0.56913 0.08049 55894.045976 0.000475 0.11384 0.01700 0.98780 0 6.41208 0.30759 5.45151 0.26150 0.72998 0.10324 0.61831 0.08744 55894.046965 0.000515 0.11148 0.01662 0.96629 0 6.18939 0.29150 5.22422 0.24603 0.68999 0.09758 0.58237 0.08236 55894.047937 0.000457 0.12998 0.01982 0.99367 0 5.77365 0.30151 4.85674 0.25363 0.75046 0.10754 0.63137 0.09047 55894.048852 0.000457 0.12063 0.01808 0.99367 0 6.25200 0.30978 5.28673 0.26195 0.75421 0.10666 0.63801 0.09023 55894.049847 0.000538 0.10801 0.01629 0.96774 0 6.05590 0.28394 5.09827 0.23904 0.65410 0.09373 0.55069 0.07891 55894.050903 0.000518 0.11713 0.01774 0.97765 0 5.74388 0.28121 4.83557 0.23674 0.67277 0.09641 0.56642 0.08117 55894.051965 0.000544 0.10864 0.01638 0.98936 0 5.79694 0.27242 4.91040 0.23074 0.62977 0.09022 0.53293 0.07637 55894.053100 0.000590 0.09142 0.01402 0.97059 0 6.31561 0.27273 5.36180 0.23153 0.57740 0.08495 0.49010 0.07212 55894.054277 0.000587 0.10124 0.01422 0.99507 0 6.46911 0.27981 5.49724 0.23774 0.65495 0.08753 0.55538 0.07422
