/* ** ** 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 59350.251226 0.000385 0.17007 0.01314 0.97744 0 19.58789 0.57371 17.97563 0.52651 3.33123 0.23828 3.05673 0.21867 59350.251992 0.000382 0.16795 0.01299 1.00000 0 19.33580 0.56964 17.91255 0.52771 3.24743 0.23230 3.01042 0.21536 59350.252776 0.000402 0.16022 0.01275 0.98561 0 18.96750 0.55155 17.65407 0.51336 3.03888 0.22516 2.82846 0.20957 59350.253537 0.000359 0.19047 0.01491 0.99194 0 18.23922 0.57019 16.97654 0.53072 3.47411 0.24933 3.23360 0.23207 59350.254330 0.000434 0.14035 0.01090 0.99333 0 20.18776 0.54496 18.76754 0.50662 2.83342 0.20627 2.63381 0.19174 59350.255210 0.000446 0.14228 0.01090 0.98052 0 19.95116 0.53542 18.51717 0.49690 2.83861 0.20372 2.63399 0.18904 59350.256014 0.000359 0.18382 0.01433 1.00000 0 18.73141 0.58009 17.43372 0.53990 3.44318 0.24631 3.20464 0.22925 59350.256735 0.000362 0.17860 0.01383 0.97600 0 19.80973 0.59328 18.43732 0.55218 3.53806 0.25263 3.29294 0.23512 59350.257554 0.000457 0.14382 0.01112 0.99367 0 18.90166 0.51368 17.45078 0.47420 2.71851 0.19680 2.51008 0.18167 59350.258381 0.000370 0.16308 0.01300 0.99219 0 20.10266 0.59211 18.70993 0.55109 3.27830 0.24290 3.05117 0.22607 59350.259125 0.000373 0.17460 0.01368 0.98450 0 19.09471 0.57186 17.77173 0.53224 3.33401 0.24130 3.10302 0.22458 59350.259892 0.000394 0.17604 0.01357 0.99265 0 18.13016 0.54573 16.87406 0.50792 3.19168 0.22643 2.97055 0.21074 59350.261029 0.000744 0.15951 0.00917 0.98444 0 19.39450 0.40834 18.01068 0.37919 3.09360 0.16547 2.87123 0.15356
