/* ** ** 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 58573.928386 0.000457 0.25633 0.00924 1.00000 0 59.88342 0.97801 49.39366 0.80645 15.35015 0.49326 12.66432 0.40684 58573.929315 0.000472 0.24430 0.00889 1.00000 0 58.65429 0.94047 49.43825 0.79272 14.32945 0.46781 12.07807 0.39422 58573.930252 0.000466 0.24983 0.00908 1.00000 0 57.60522 0.93610 48.99678 0.79622 14.39175 0.46773 12.24112 0.39783 58573.931196 0.000477 0.23467 0.00856 1.00000 0 59.56902 0.93623 50.55301 0.79454 13.97909 0.46020 11.86406 0.39057 58573.932124 0.000451 0.25976 0.00948 1.00000 0 57.71362 0.95742 48.65771 0.80706 14.99148 0.48717 12.63347 0.41058 58573.933024 0.000448 0.25142 0.00914 1.00000 0 59.64445 0.96807 50.64796 0.82205 14.99600 0.48789 12.73407 0.41430 58573.933944 0.000472 0.24563 0.00905 1.00000 0 58.01551 0.93664 49.05320 0.79194 14.25008 0.47179 12.04538 0.39883 58573.934885 0.000469 0.25112 0.00913 1.00000 0 57.59198 0.93715 48.56802 0.79029 14.46262 0.47009 12.20856 0.39678 58573.936091 0.000738 0.24722 0.00715 0.99672 0 59.10822 0.75579 49.59279 0.63408 14.61260 0.37912 12.25715 0.31804 58573.997714 0.000420 0.26083 0.00940 1.00000 0 58.06161 0.95453 52.58984 0.86452 15.14416 0.48596 13.71416 0.44007 58573.998556 0.000422 0.25841 0.00950 1.00000 0 57.45348 0.94327 52.15390 0.85623 14.84681 0.48864 13.47732 0.44354 58573.999491 0.000512 0.27471 0.00905 1.00000 0 54.63145 0.83845 49.71241 0.76295 15.00799 0.43763 13.65666 0.39823
