/* ** ** 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 59195.584447 0.000477 0.19884 0.01602 0.99394 0 18.54677 0.60735 11.93912 0.39014 3.68777 0.27156 2.37592 0.17492 59195.585423 0.000498 0.21397 0.01700 0.98256 0 18.81871 0.63142 10.93247 0.36653 4.02666 0.29002 2.35007 0.16911 59195.586485 0.000564 0.19248 0.01534 0.99487 0 17.79265 0.57049 10.53658 0.33779 3.42466 0.24985 2.02830 0.14792 59195.587572 0.000524 0.20882 0.01677 0.99448 0 18.06586 0.60132 10.41214 0.34648 3.77250 0.27575 2.17492 0.15904 59195.588698 0.000602 0.17557 0.01392 0.99038 0 18.64913 0.57014 10.77363 0.32928 3.27415 0.23953 1.90042 0.13897 59195.589824 0.000524 0.20155 0.01629 0.98895 0 18.56156 0.60753 10.80506 0.35361 3.74101 0.27646 2.17775 0.16098 59195.590888 0.000541 0.20849 0.01667 1.00000 0 17.32487 0.58034 10.09251 0.33798 3.61207 0.26230 2.10333 0.15277 59195.592017 0.000587 0.19727 0.01571 0.99015 0 16.82343 0.54829 9.93822 0.32397 3.31878 0.24108 1.95683 0.14213 59195.593174 0.000570 0.19976 0.01572 1.00000 0 17.53188 0.56003 10.38211 0.33162 3.50219 0.25184 2.06944 0.14878
