/* ** ** 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 59706.012482 0.000436 0.17816 0.02728 0.99892 1 17.38131 1.04997 3.84584 0.23230 3.09669 0.43572 0.68478 0.09635 59706.013861 0.000428 0.13924 0.01077 0.98649 0 21.31857 0.56868 19.39338 0.51730 2.96841 0.21545 2.69975 0.19598 59706.014746 0.000457 0.13673 0.01043 0.98734 0 20.50872 0.53994 18.68408 0.49189 2.80420 0.20066 2.55395 0.18274 59706.015944 0.000741 0.15508 0.00878 0.98508 0 20.73542 0.43375 18.93644 0.39607 3.21558 0.16908 2.93965 0.15455 59706.081946 0.000492 0.13392 0.01028 0.98824 0 19.26067 0.50690 17.53956 0.46158 2.57931 0.18598 2.35094 0.16949 59706.082874 0.000437 0.14465 0.01119 1.00000 0 19.85925 0.54648 18.08411 0.49761 2.87274 0.20760 2.61943 0.18928 59706.083766 0.000454 0.15319 0.01180 0.98726 0 18.38194 0.51593 16.80347 0.47162 2.81586 0.20198 2.57396 0.18462 59706.084686 0.000466 0.14347 0.01087 0.98758 0 19.28905 0.51927 17.70289 0.47657 2.76735 0.19609 2.53976 0.17996 59706.085600 0.000448 0.13216 0.01016 0.99355 0 21.17488 0.55474 19.43382 0.50912 2.79850 0.20222 2.56840 0.18559 59706.086752 0.000703 0.12986 0.00841 0.99177 0 19.57797 0.43634 17.87708 0.39825 2.54234 0.15454 2.31932 0.14096
