/* ** ** 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 58648.152478 0.000339 0.18702 0.01475 1.00000 0 20.07717 0.62384 17.95022 0.55770 3.75474 0.27229 3.35893 0.24362 58648.153132 0.000315 0.19537 0.01512 0.99083 0 21.28815 0.66930 18.97563 0.59661 4.15913 0.29410 3.70987 0.26233 58648.153815 0.000367 0.17366 0.01368 0.98425 0 20.30181 0.60651 18.04692 0.53911 3.52571 0.25690 3.13373 0.22826 58648.154521 0.000339 0.19295 0.01477 0.97436 0 20.84105 0.63925 18.62454 0.57125 4.02122 0.28202 3.59127 0.25186 58648.155261 0.000402 0.15584 0.01197 0.99281 0 20.84653 0.58905 18.52822 0.52349 3.24875 0.23210 2.89010 0.20644 58648.156011 0.000347 0.17555 0.01395 0.99167 0 20.94824 0.63446 18.63247 0.56428 3.67748 0.27023 3.27025 0.24025 58648.156694 0.000336 0.18965 0.01485 1.00000 0 20.42315 0.64156 18.10044 0.56855 3.87325 0.27784 3.42720 0.24584 58648.157379 0.000350 0.19811 0.01546 0.99174 0 18.83818 0.59805 16.73813 0.53136 3.73199 0.26615 3.31758 0.23658 58648.158048 0.000318 0.18874 0.01480 1.00000 0 21.62472 0.67601 19.05376 0.59564 4.08148 0.29351 3.59593 0.25861 58648.158748 0.000382 0.17452 0.01366 1.00000 0 19.25018 0.58108 17.10074 0.51614 3.35961 0.24261 2.98692 0.21572 58648.159526 0.000396 0.15820 0.01219 0.98540 0 20.96041 0.59525 18.58381 0.52774 3.31594 0.23748 2.93949 0.21050 58648.160282 0.000359 0.18171 0.01414 0.98387 0 20.45107 0.61927 18.04872 0.54652 3.71606 0.26633 3.28101 0.23513 58648.161219 0.000579 0.18921 0.01161 0.98500 0 19.48307 0.47188 17.46112 0.42291 3.68634 0.20786 3.30110 0.18615
