/* ** ** 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 56780.048236 0.000240 0.17333 0.01342 1.00000 0 29.83872 0.88890 27.63110 0.82313 5.17193 0.36975 4.78937 0.34239 56780.048728 0.000252 0.16361 0.01295 1.00000 0 29.76788 0.87387 27.54409 0.80859 4.87046 0.35799 4.50664 0.33125 56780.049211 0.000231 0.18071 0.01418 0.98750 0 29.84531 0.91064 27.62456 0.84288 5.39322 0.38983 4.99201 0.36083 56780.049694 0.000252 0.17874 0.01396 1.00000 0 27.67846 0.84608 25.44758 0.77780 4.94724 0.35560 4.55107 0.32715 56780.050186 0.000240 0.17214 0.01404 1.00000 0 28.86555 0.88506 26.72031 0.81929 4.96898 0.37552 4.59968 0.34761 56780.050684 0.000258 0.16939 0.01301 1.00000 0 29.15973 0.86050 26.61727 0.78540 4.93938 0.35036 4.50669 0.31962 56780.051173 0.000231 0.18305 0.01432 1.00000 0 29.20835 0.90330 27.03767 0.83617 5.34665 0.38434 4.94929 0.35578 56780.051685 0.000281 0.15547 0.01226 1.00000 0 28.53565 0.81477 25.97619 0.74163 4.43655 0.32606 4.04204 0.29710 56780.052220 0.000255 0.16816 0.01310 1.00000 0 29.18407 0.86256 26.74723 0.79046 4.90762 0.35377 4.50423 0.32473 56780.052741 0.000266 0.16238 0.01246 1.00000 0 29.43015 0.84869 26.87511 0.77491 4.77901 0.33995 4.36439 0.31043 56780.053245 0.000237 0.17566 0.01356 1.00000 0 30.57193 0.92059 27.71977 0.83471 5.37011 0.38185 4.86698 0.34604 56780.053806 0.000324 0.17172 0.01172 0.99506 0 29.41394 0.77864 26.61432 0.70451 5.05108 0.31769 4.56969 0.28740
