/* ** ** 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 54978.177872 0.000286 0.16978 0.01320 0.98990 0 26.00110 0.76254 23.94835 0.70230 4.41440 0.31796 4.06198 0.29248 54978.178413 0.000255 0.20532 0.01626 0.98864 0 23.85193 0.77521 22.17348 0.72066 4.89718 0.35354 4.55254 0.32866 54978.178948 0.000281 0.18109 0.01415 0.98969 0 24.48323 0.74640 22.76215 0.69393 4.43372 0.31904 4.12205 0.29662 54978.179515 0.000286 0.18097 0.01382 0.98990 0 24.80715 0.74198 23.06360 0.68983 4.48934 0.31533 4.17381 0.29317 54978.180111 0.000310 0.16207 0.01240 0.99065 0 25.25617 0.71999 23.48082 0.66938 4.09317 0.29060 3.80545 0.27017 54978.180704 0.000284 0.19017 0.01466 0.98980 0 23.61685 0.73044 21.95649 0.67908 4.49129 0.31704 4.17554 0.29475 54978.181286 0.000298 0.17858 0.01392 1.00000 0 23.26179 0.70631 21.62307 0.65655 4.15410 0.29815 3.86137 0.27714 54978.181850 0.000266 0.18436 0.01421 1.00000 0 25.41410 0.77907 23.62303 0.72417 4.68537 0.33131 4.35508 0.30795 54978.182420 0.000304 0.16837 0.01292 0.99048 0 24.77984 0.72148 23.03721 0.67074 4.17206 0.29620 3.87863 0.27537 54978.183016 0.000292 0.17836 0.01379 1.00000 0 23.97014 0.72213 22.28180 0.67127 4.27525 0.30429 3.97400 0.28285 54978.183540 0.000231 0.21891 0.01730 1.00000 0 24.54957 0.82238 22.82429 0.76458 5.37424 0.38474 4.99655 0.35770 54978.184064 0.000292 0.16469 0.01317 0.99010 0 25.32791 0.74532 23.54860 0.69296 4.17124 0.31009 3.87821 0.28830 54978.184642 0.000286 0.16645 0.01308 1.00000 0 25.61296 0.75573 23.81394 0.70265 4.26325 0.31039 3.96381 0.28859 54978.185218 0.000289 0.18216 0.01422 1.00000 0 23.48321 0.72038 21.83313 0.66976 4.27779 0.30703 3.97721 0.28546 54978.185782 0.000275 0.18545 0.01468 1.00000 0 24.10119 0.74751 22.40776 0.69499 4.46955 0.32559 4.15552 0.30272 54978.186332 0.000275 0.17950 0.01411 1.00000 0 24.85487 0.76158 23.10854 0.70807 4.46155 0.32293 4.14808 0.30024 54978.186943 0.000336 0.15016 0.01145 0.99138 0 24.99665 0.68886 23.12084 0.63715 3.75361 0.26698 3.46971 0.24678 54978.187585 0.000307 0.15862 0.01213 1.00000 0 25.65379 0.73078 23.85146 0.67944 4.06911 0.28868 3.78321 0.26840 54978.188375 0.000483 0.18151 0.01100 0.97605 0 23.70679 0.56039 22.04164 0.52103 4.30313 0.24015 4.00088 0.22328
