/* ** ** 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 57719.263607 0.000385 0.12776 0.01946 0.96992 0 7.25756 0.36680 6.12771 0.30964 0.92722 0.13321 0.77601 0.11148 57719.264377 0.000385 0.12515 0.01866 0.99248 0 7.40156 0.37086 6.24130 0.31270 0.92632 0.13010 0.78137 0.10972 57719.265219 0.000457 0.10422 0.01568 0.96835 0 7.37252 0.33756 6.22419 0.28496 0.76837 0.11010 0.64794 0.09283 57719.266231 0.000556 0.08562 0.01278 0.98438 0 7.25017 0.30365 6.11741 0.25617 0.62079 0.08897 0.52452 0.07515 57719.267264 0.000477 0.09536 0.01429 0.97576 0 7.71669 0.34003 6.45861 0.28459 0.73587 0.10543 0.61574 0.08822 57719.268219 0.000477 0.08686 0.01314 0.99394 0 8.13836 0.34625 6.89874 0.29349 0.70692 0.10266 0.59818 0.08683 57719.269209 0.000512 0.07968 0.01174 0.98870 0 8.64169 0.34639 7.25861 0.29094 0.68859 0.09763 0.57793 0.08196 57719.270062 0.000336 0.13633 0.02060 0.98276 0 7.77840 0.40566 6.50767 0.33939 1.06042 0.15039 0.88717 0.12582 57719.270942 0.000544 0.07520 0.01120 0.97872 0 8.53192 0.33350 7.22018 0.28223 0.64164 0.09218 0.54405 0.07816 57719.271989 0.000503 0.09029 0.01334 0.97126 0 7.77279 0.33092 6.55669 0.27913 0.70182 0.09926 0.59270 0.08382 57719.272898 0.000405 0.11434 0.01708 0.97857 0 7.52628 0.36117 6.40348 0.30724 0.86055 0.12171 0.73114 0.10340 57719.273812 0.000509 0.09212 0.01359 0.96696 0 7.98868 0.33158 6.76036 0.28058 0.73592 0.10415 0.62317 0.08814 57720.406716 0.000324 0.11659 0.02904 0.97321 0 7.21900 0.58334 3.13412 0.24205 0.84163 0.19831 0.36281 0.08233 57720.407433 0.000394 0.14847 0.03184 0.96324 0 7.73024 0.61300 2.50178 0.19793 1.14774 0.22865 0.39364 0.07808 57720.408371 0.000544 0.09286 0.02173 0.96809 0 7.95369 0.54780 2.35761 0.16235 0.73858 0.16516 0.22015 0.04923 57720.409644 0.000729 0.06674 0.01490 0.96825 0 8.88669 0.50052 2.67495 0.15066 0.59309 0.12815 0.17850 0.03857
