/* ** ** 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 54924.981892 0.000388 0.17038 0.01318 0.97761 0 19.17121 0.55748 17.82765 0.51841 3.26638 0.23423 3.03754 0.21782 54924.982665 0.000385 0.17116 0.01338 0.98496 0 18.91265 0.56167 17.58631 0.52228 3.23718 0.23403 3.01015 0.21762 54924.983385 0.000336 0.19621 0.01538 0.99138 0 18.96716 0.60071 17.63458 0.55851 3.72160 0.26687 3.46015 0.24813 54924.984129 0.000408 0.15490 0.01202 0.99291 0 19.55653 0.55257 18.18340 0.51378 3.02934 0.21901 2.81664 0.20363 54924.984971 0.000434 0.15078 0.01162 0.99333 0 18.95379 0.52719 17.62288 0.49018 2.85781 0.20546 2.65714 0.19103 54924.985836 0.000431 0.15462 0.01181 0.97987 0 19.12865 0.53168 17.78539 0.49435 2.95774 0.21040 2.75003 0.19562 54924.986643 0.000376 0.17719 0.01397 1.00000 0 18.33901 0.55844 17.05052 0.51920 3.24944 0.23623 3.02112 0.21963 54924.987436 0.000417 0.15155 0.01163 1.00000 0 19.58982 0.54772 18.21406 0.50925 2.96890 0.21227 2.76040 0.19736 54924.988255 0.000402 0.17059 0.01310 0.99281 0 18.40919 0.54156 17.03878 0.50123 3.14048 0.22273 2.90642 0.20613 54924.989051 0.000394 0.17069 0.01329 0.97794 0 18.86363 0.55498 17.45331 0.51350 3.21992 0.23221 2.97995 0.21488 54924.989829 0.000385 0.16869 0.01311 1.00000 0 19.14219 0.56386 17.64246 0.51965 3.22912 0.23222 2.97680 0.21402 54924.990555 0.000341 0.18490 0.01439 0.99153 0 19.89901 0.60911 18.49031 0.56598 3.67931 0.26318 3.41812 0.24448 54924.991288 0.000391 0.16665 0.01295 1.00000 0 18.93238 0.55812 17.59606 0.51873 3.15503 0.22683 2.93270 0.21084 54924.992020 0.000341 0.19656 0.01592 0.98305 0 18.31681 0.58759 16.94648 0.54366 3.60037 0.26771 3.33110 0.24765 54924.992714 0.000353 0.19067 0.01494 1.00000 0 18.39839 0.58018 17.10588 0.53942 3.50807 0.25156 3.26162 0.23389 54924.993733 0.000666 0.15941 0.00967 0.98261 0 19.34622 0.43090 17.98684 0.40062 3.08398 0.17408 2.86729 0.16185
