/* ** ** 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 58519.257814 0.000350 0.16146 0.01235 1.00000 0 25.92502 0.74101 20.90185 0.59680 4.18581 0.29709 3.34811 0.23739 58519.258520 0.000356 0.15512 0.01236 1.00000 0 25.34168 0.72379 20.51880 0.58589 3.93108 0.29240 3.17610 0.23608 58519.259203 0.000327 0.17037 0.01330 1.00000 0 25.86389 0.76903 20.61380 0.61294 4.40652 0.31814 3.51819 0.25393 58519.259883 0.000353 0.16621 0.01294 0.98361 0 24.76961 0.72457 19.94157 0.58333 4.11690 0.29708 3.31296 0.23912 58519.260618 0.000382 0.14769 0.01155 0.98485 0 25.19022 0.70574 20.41940 0.57199 3.72043 0.27168 3.01361 0.22007 58519.261321 0.000321 0.17834 0.01380 0.99099 0 25.11551 0.75748 20.44427 0.61654 4.47901 0.31917 3.64649 0.25985 58519.261987 0.000344 0.18189 0.01426 0.98319 0 23.20916 0.71526 18.58863 0.57285 4.22150 0.30425 3.37887 0.24358 58519.262684 0.000353 0.15824 0.01228 1.00000 0 25.68304 0.73778 20.52835 0.58966 4.06411 0.29305 3.24039 0.23359 58519.263347 0.000310 0.19031 0.01481 1.00000 0 24.45533 0.76511 19.72059 0.61684 4.65398 0.33170 3.74873 0.26714 58519.264027 0.000370 0.15619 0.01211 1.00000 0 24.79855 0.70747 19.74252 0.56326 3.87332 0.27935 3.08850 0.22265 58519.264846 0.000448 0.16740 0.01148 0.99719 0 25.10649 0.64850 20.07301 0.51838 4.20274 0.26711 3.35412 0.21318 58519.324556 0.000440 0.17546 0.01384 0.99342 0 25.15520 0.76719 14.81335 0.45131 4.41361 0.32101 2.60598 0.18912 58519.325508 0.000512 0.15882 0.01263 0.98305 0 24.91540 0.72538 14.04043 0.40872 3.95713 0.29284 2.23064 0.16509 58519.326587 0.000567 0.15235 0.01187 0.98980 0 23.93349 0.67792 13.34935 0.37797 3.64626 0.26458 2.02837 0.14720 58519.327640 0.000486 0.16372 0.01301 0.99405 0 25.33307 0.74484 14.25977 0.41927 4.14749 0.30610 2.33614 0.17242 58519.328887 0.000761 0.16139 0.01069 0.98859 0 23.71560 0.58317 13.32627 0.32763 3.82738 0.23532 2.14938 0.13216
