/* ** ** 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 55659.244009 0.000648 0.12431 0.01912 0.74554 0 15.46798 0.78905 4.72587 0.24064 1.92278 0.27909 0.58754 0.08505 55659.245216 0.000558 0.13462 0.02050 0.95855 0 13.24752 0.69151 3.98146 0.20783 1.78340 0.25517 0.53591 0.07667 55659.246287 0.000506 0.11845 0.01772 0.95429 0 16.78397 0.81863 5.07019 0.24731 1.98803 0.28115 0.59980 0.08482 55659.247450 0.000657 0.09473 0.01418 0.97357 0 15.62743 0.68580 4.73481 0.20779 1.48043 0.21180 0.44861 0.06418 55659.248633 0.000527 0.12971 0.01932 0.97253 0 14.68123 0.74434 4.45262 0.22574 1.90433 0.26666 0.57723 0.08083 55659.249675 0.000515 0.12953 0.01992 0.97191 0 14.41921 0.74544 4.37708 0.22627 1.86770 0.27045 0.56716 0.08210 55659.250777 0.000587 0.11078 0.01652 0.95567 0 15.55176 0.72727 4.70346 0.21995 1.72276 0.24401 0.52137 0.07384 55659.252097 0.000732 0.10339 0.01580 0.81028 0 15.23222 0.70730 4.60787 0.21397 1.57492 0.22930 0.47613 0.06933 55659.253468 0.000634 0.10605 0.01632 0.96804 0 14.30110 0.67509 4.31539 0.20371 1.51661 0.22213 0.45800 0.06708 55659.254493 0.000391 0.09258 0.01956 0.93333 0 13.94288 0.84486 4.24749 0.25736 1.29083 0.26120 0.39342 0.07960 55659.255526 0.000642 0.12872 0.01949 0.88289 0 13.27622 0.68108 3.98891 0.20462 1.70887 0.24342 0.51344 0.07313 55659.256903 0.000729 0.10992 0.01556 0.93254 0 14.53839 0.63988 4.36818 0.19224 1.59808 0.21498 0.47938 0.06447
