/* ** ** 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 58848.817477 0.000336 0.18032 0.01415 0.99138 0 25.55419 0.77633 19.45328 0.58574 4.60794 0.33326 3.48757 0.24858 58848.818180 0.000367 0.15574 0.01230 0.98425 0 25.75667 0.73516 20.04792 0.57180 4.01127 0.29546 3.11888 0.22938 58848.818909 0.000362 0.16708 0.01318 1.00000 0 25.51493 0.75907 18.77184 0.55834 4.26299 0.31150 3.13329 0.22893 58848.819662 0.000391 0.15587 0.01194 1.00000 0 25.99660 0.73708 18.94814 0.53724 4.05199 0.28841 2.95456 0.21029 58848.820443 0.000391 0.16108 0.01234 0.98519 0 25.35180 0.72265 18.84952 0.53728 4.08377 0.29037 3.03063 0.21546 58848.821204 0.000370 0.16099 0.01251 0.99219 0 26.17418 0.75879 19.32537 0.56015 4.21370 0.30387 3.11231 0.22443 58848.821910 0.000336 0.18191 0.01443 0.99138 0 25.45650 0.78661 18.73928 0.57901 4.63078 0.33833 3.40575 0.24884 58848.822575 0.000330 0.18745 0.01453 0.99123 0 25.35944 0.79064 18.94164 0.59050 4.75373 0.33748 3.54751 0.25185 58848.823238 0.000333 0.17512 0.01385 0.99130 0 26.93906 0.81662 19.60481 0.59410 4.71745 0.34473 3.43562 0.25102 58848.823976 0.000405 0.14953 0.01157 0.98571 0 25.85797 0.71823 19.24528 0.53435 3.86662 0.27913 2.88021 0.20797 58848.824754 0.000373 0.16903 0.01318 0.98450 0 25.09148 0.74329 18.40907 0.54527 4.24121 0.30588 3.11231 0.22443 58848.825498 0.000370 0.16829 0.01305 0.99219 0 25.25059 0.74742 18.55243 0.54916 4.24936 0.30450 3.12649 0.22398 58848.826224 0.000356 0.17070 0.01317 1.00000 0 25.77794 0.76613 19.00726 0.56482 4.40034 0.31324 3.24281 0.23080 58848.826959 0.000379 0.15391 0.01191 1.00000 0 26.68460 0.75952 19.73785 0.56171 4.10700 0.29542 3.03257 0.21811 58848.827688 0.000350 0.16728 0.01283 1.00000 0 26.55127 0.78244 19.92520 0.58697 4.44148 0.31460 3.32952 0.23578 58848.828423 0.000385 0.15804 0.01242 1.00000 0 24.99965 0.72472 18.59335 0.53893 3.95082 0.28867 2.94482 0.21516 58848.829161 0.000353 0.17121 0.01326 0.97541 0 26.48646 0.77972 19.49380 0.57385 4.53466 0.32489 3.33667 0.23904 58848.830046 0.000532 0.16994 0.01069 0.98913 0 26.56749 0.63438 19.69096 0.47020 4.51499 0.26277 3.34077 0.19444
