/* ** ** 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 56302.474846 0.000443 0.09950 0.01480 0.98693 0 7.49069 0.33511 6.73012 0.30109 0.74532 0.10574 0.66965 0.09500 56302.475772 0.000483 0.08567 0.01278 0.97006 0 7.99240 0.33106 7.12923 0.29531 0.68474 0.09817 0.61181 0.08768 56302.476773 0.000518 0.07924 0.01165 0.98883 0 7.98694 0.32020 7.14964 0.28663 0.63287 0.08950 0.56591 0.08003 56302.477840 0.000550 0.06900 0.01035 0.98421 0 8.58047 0.32295 7.61676 0.28667 0.59205 0.08598 0.52438 0.07617 56302.478859 0.000469 0.08219 0.01210 0.98765 0 8.62811 0.35304 7.62660 0.31206 0.70912 0.10029 0.62604 0.08854 56302.479750 0.000422 0.09668 0.01450 0.97260 0 8.07409 0.35695 7.22082 0.31923 0.78060 0.11187 0.69798 0.10003 56302.480650 0.000477 0.08449 0.01245 0.98788 0 8.15584 0.33688 7.27662 0.30054 0.68908 0.09746 0.61452 0.08691 56302.481544 0.000417 0.10042 0.01491 0.98611 0 7.88422 0.35529 7.03697 0.31710 0.79177 0.11198 0.70540 0.09976 56302.482406 0.000446 0.09041 0.01336 0.98701 0 8.14575 0.35019 7.28020 0.31295 0.73649 0.10416 0.65899 0.09320 56302.483326 0.000475 0.08753 0.01291 0.97561 0 8.06575 0.33719 7.14920 0.29887 0.70597 0.09985 0.62604 0.08854 56302.484345 0.000544 0.07165 0.01063 0.98936 0 8.28711 0.31783 7.43349 0.28508 0.59377 0.08510 0.53287 0.07637 56302.485395 0.000506 0.08270 0.01248 0.96571 0 7.83329 0.32051 7.01296 0.28695 0.64782 0.09409 0.58024 0.08428 56302.486428 0.000527 0.05659 0.01020 0.96703 0 7.61990 0.30955 6.81979 0.27706 0.43118 0.07572 0.38642 0.06787 56302.487456 0.000501 0.07748 0.01182 0.97110 0 8.29515 0.33199 7.45231 0.29826 0.64272 0.09463 0.57742 0.08502 56302.488755 0.000799 0.09092 0.01024 0.97464 0 8.15581 0.26187 7.27961 0.23375 0.74149 0.08008 0.66204 0.07147
