/* ** ** 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 54381.645047 0.000715 0.13180 0.01009 0.99190 0 15.44929 0.39911 12.31301 0.31809 2.03629 0.14672 1.62437 0.11702 54381.646482 0.000720 0.13655 0.01037 0.99598 0 14.75922 0.39108 11.78382 0.31224 2.01540 0.14336 1.60883 0.11444 54381.648606 0.001403 0.11771 0.00686 0.98351 0 15.08753 0.28241 12.02791 0.22512 1.77597 0.09806 1.41528 0.07814 54381.712422 0.000729 0.14511 0.01097 0.99206 0 14.34587 0.39015 11.09332 0.30171 2.08171 0.14684 1.61068 0.11361 54381.713944 0.000793 0.12175 0.00930 1.00000 0 15.31347 0.38604 11.84569 0.29860 1.86440 0.13447 1.44241 0.10403 54381.716056 0.001319 0.12777 0.00745 0.97736 0 15.19014 0.29633 11.83104 0.23080 1.94077 0.10665 1.51159 0.08306 54381.779202 0.000842 0.11776 0.00900 0.99313 0 14.74185 0.36237 11.61710 0.28556 1.73607 0.12565 1.36850 0.09906 54381.780958 0.000914 0.11237 0.00859 0.97468 0 14.55256 0.34771 11.37325 0.27174 1.63521 0.11870 1.27758 0.09272 54381.782958 0.001085 0.11319 0.00767 0.99114 0 14.96381 0.32232 11.78764 0.25389 1.69372 0.10882 1.33302 0.08563 54381.845949 0.000923 0.12564 0.00960 0.96865 0 13.44378 0.33804 10.17418 0.25584 1.68913 0.12180 1.27915 0.09224 54381.847764 0.000891 0.12246 0.00935 0.98377 0 14.03652 0.35180 10.65228 0.26694 1.71886 0.12394 1.30448 0.09407 54381.849682 0.001027 0.11215 0.00849 0.97935 0 13.65362 0.32417 10.29564 0.24443 1.53121 0.11001 1.15474 0.08295 54381.913293 0.000906 0.12033 0.00925 0.99681 0 13.49461 0.33808 10.46370 0.26215 1.62382 0.11798 1.26049 0.09158 54381.915130 0.000932 0.12336 0.00943 0.99379 0 12.95586 0.32816 10.01048 0.25352 1.59818 0.11530 1.23475 0.08910 54381.917066 0.001004 0.09856 0.00791 0.98177 0 13.46897 0.32230 10.39171 0.24866 1.32750 0.10163 1.02411 0.07839 54381.980047 0.000992 0.10280 0.00778 0.99417 0 14.47606 0.33266 11.26194 0.25880 1.48817 0.10734 1.15900 0.08359 54381.982874 0.001834 0.12037 0.00645 0.98580 0 13.73672 0.24000 10.56216 0.18453 1.65353 0.08378 1.27051 0.06437
