/* ** ** 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 56009.705578 0.001386 0.15505 0.01094 0.97751 0 18.41476 0.47050 6.70712 0.17040 2.85522 0.18771 1.03667 0.06778 56009.967990 0.000576 0.14935 0.01152 0.97990 0 17.66655 0.48630 13.74470 0.37752 2.63849 0.19007 2.03652 0.14658 56009.969110 0.000544 0.13472 0.01055 0.98936 0 18.77472 0.49745 15.66984 0.41515 2.52929 0.18649 2.10607 0.15532 56009.970230 0.000576 0.12687 0.00959 0.98995 0 19.25624 0.49018 15.95039 0.40600 2.44304 0.17395 2.02445 0.14412 56009.971312 0.000506 0.15898 0.01214 0.99429 0 17.49654 0.49929 14.53612 0.41481 2.78160 0.19704 2.31508 0.16398 56009.972351 0.000532 0.14482 0.01122 0.96739 0 18.44529 0.49736 15.26962 0.41170 2.67133 0.19406 2.20938 0.16052 56009.973450 0.000567 0.12420 0.00979 0.97449 0 19.49806 0.49624 16.27085 0.41409 2.42158 0.18068 2.02028 0.15084 56009.974596 0.000579 0.12950 0.01000 0.99500 0 18.41166 0.47642 15.33514 0.39678 2.38434 0.17346 1.98707 0.14458 56009.975693 0.000518 0.15527 0.01193 0.98324 0 17.38537 0.49030 14.59472 0.41162 2.69949 0.19302 2.26688 0.16206 56009.976740 0.000530 0.14938 0.01135 0.99454 0 17.67410 0.48693 14.80739 0.40796 2.64023 0.18702 2.21332 0.15677 56009.977863 0.000593 0.14961 0.01086 0.99512 0 17.72816 0.45908 14.91924 0.38633 2.65230 0.17994 2.23373 0.15154
