/* ** ** 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 59373.216396 0.000651 0.12000 0.00921 0.98222 0 16.64186 0.41383 14.84322 0.36906 1.99697 0.14498 1.78044 0.12922 59373.217736 0.000689 0.11387 0.00859 0.99160 0 16.45892 0.39978 14.85006 0.36070 1.87415 0.13392 1.69100 0.12083 59373.219194 0.000770 0.09906 0.00753 0.99248 0 16.79594 0.38130 15.04453 0.34154 1.66380 0.12076 1.49044 0.10818 59373.220730 0.000767 0.10523 0.00793 0.98491 0 16.08694 0.37491 14.44757 0.33669 1.69287 0.12127 1.52135 0.10899 59373.222105 0.000608 0.12953 0.00996 0.99524 0 16.29383 0.42170 14.61718 0.37826 2.11049 0.15281 1.89225 0.13698 59373.223375 0.000663 0.11751 0.00879 0.99127 0 16.64396 0.40752 15.02122 0.36779 1.95576 0.13829 1.76505 0.12481 59373.224613 0.000576 0.13473 0.01027 0.98492 0 16.83656 0.44129 15.19577 0.39828 2.26845 0.16231 2.04737 0.14649 59373.225875 0.000686 0.11261 0.00840 0.97468 0 17.12576 0.40647 15.41096 0.36574 1.92852 0.13637 1.73449 0.12265 59373.227516 0.000955 0.12629 0.00782 0.98788 0 16.45502 0.33799 14.82716 0.30454 2.07817 0.12137 1.87256 0.10935
