/* ** ** 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 57724.442926 0.000489 0.09403 0.01391 0.98225 0 7.86400 0.34094 6.43504 0.27892 0.73945 0.10459 0.60341 0.08534 57724.443974 0.000558 0.07811 0.01191 0.98446 0 7.81654 0.31792 6.53697 0.26586 0.61053 0.08976 0.51105 0.07514 57724.444862 0.000330 0.12495 0.01901 0.98246 0 8.44661 0.43183 7.08144 0.36204 1.05543 0.15119 0.88522 0.12681 57724.445487 0.000295 0.15256 0.02349 0.99020 0 7.70799 0.43561 6.43338 0.36353 1.17591 0.16844 0.98163 0.14062 57724.446135 0.000353 0.13138 0.01978 0.98361 0 7.63078 0.39410 6.35564 0.32827 1.00256 0.14179 0.83472 0.11805 57724.446859 0.000370 0.12415 0.01887 0.98438 0 7.61194 0.38629 6.33833 0.32161 0.94499 0.13538 0.78686 0.11272 57724.447573 0.000344 0.13626 0.02055 0.95798 0 7.68706 0.40314 6.44362 0.33789 1.04742 0.14813 0.87866 0.12426 57724.448303 0.000385 0.11716 0.01795 0.97744 0 7.70296 0.37742 6.42596 0.31484 0.90246 0.13098 0.75478 0.10953 57724.449098 0.000411 0.10740 0.01640 0.99296 0 7.75775 0.36898 6.49119 0.30873 0.83321 0.12090 0.69590 0.10099 57724.449816 0.000307 0.05674 0.01306 0.98113 0 8.08286 0.44131 6.78438 0.37041 0.45865 0.10256 0.38526 0.08615 57724.450458 0.000336 0.12689 0.01953 0.97414 0 8.07918 0.41304 6.83513 0.34944 1.02520 0.14883 0.86834 0.12601 57724.451196 0.000402 0.10812 0.01714 0.96403 0 7.90526 0.37677 6.63804 0.31639 0.85474 0.12919 0.71669 0.10839 57724.451899 0.000301 0.14533 0.02226 0.97115 0 7.99818 0.43308 6.73797 0.36482 1.16238 0.16651 0.98163 0.14062 57724.452637 0.000437 0.09859 0.01499 0.96689 0 8.12563 0.36695 6.80775 0.30740 0.80114 0.11628 0.67207 0.09753 57724.453621 0.000547 0.10255 0.01382 0.98413 0 7.74776 0.31779 6.44014 0.26413 0.79453 0.10198 0.66228 0.08499
