/* ** ** 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 59234.098891 0.000530 0.09554 0.01432 0.94536 0 6.64851 0.29091 5.99706 0.26237 0.63517 0.09103 0.57290 0.08211 59234.099826 0.000405 0.13108 0.02025 0.96429 0 6.09611 0.32006 5.54116 0.29093 0.79905 0.11607 0.72634 0.10551 59234.100763 0.000532 0.09627 0.01433 0.98370 0 6.44794 0.28268 5.85698 0.25677 0.62077 0.08833 0.56388 0.08024 59234.101764 0.000469 0.09522 0.01412 0.98148 0 7.33469 0.32618 6.60669 0.29378 0.69844 0.09878 0.62998 0.08909 59234.102684 0.000451 0.11641 0.01791 0.98077 0 6.11972 0.30204 5.55851 0.27434 0.71241 0.10378 0.64709 0.09427 59234.103483 0.000347 0.13173 0.02011 0.96667 0 7.14192 0.37479 6.48617 0.34037 0.94079 0.13484 0.85441 0.12246 59234.104698 0.000868 0.10666 0.01173 0.98225 0 6.48892 0.22424 5.89380 0.20368 0.69213 0.07229 0.62867 0.06566 59234.147058 0.000498 0.10527 0.01567 0.98837 0 6.44930 0.29931 5.60661 0.26011 0.67894 0.09603 0.58922 0.08333 59234.148077 0.000521 0.09249 0.01421 0.98333 0 6.79159 0.29873 5.93268 0.26096 0.62813 0.09247 0.54812 0.08069 59234.149029 0.000431 0.11915 0.01852 0.97987 0 6.36678 0.31808 5.57711 0.27863 0.75861 0.11167 0.66450 0.09782 59234.150062 0.000602 0.10042 0.01375 0.97596 0 6.66968 0.27580 5.84476 0.24169 0.66979 0.08743 0.58695 0.07662
