/* ** ** 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 57485.893322 0.000567 0.17176 0.01341 0.98980 0 21.08861 0.62867 11.89745 0.35439 3.62211 0.26144 2.03714 0.14694 57485.894497 0.000608 0.14626 0.01114 0.97143 0 22.14292 0.59977 13.38904 0.36266 3.23859 0.23056 1.95513 0.13917 57485.895828 0.000723 0.13452 0.00976 0.99371 0 22.24289 0.56054 13.14448 0.33124 2.99205 0.20369 1.76749 0.12033 57485.942303 0.000425 0.15099 0.01176 1.00000 0 21.33106 0.60473 17.80229 0.50445 3.22084 0.23372 2.67691 0.19426 57485.943203 0.000475 0.13621 0.01053 0.99390 0 21.33459 0.56963 17.76902 0.47438 2.90605 0.21082 2.41415 0.17519 57485.944117 0.000440 0.15034 0.01158 0.98026 0 21.38183 0.59115 17.77819 0.49145 3.21459 0.23115 2.66644 0.19175 57485.945182 0.000625 0.13539 0.00913 0.99021 0 21.80341 0.50275 18.02879 0.41566 2.95190 0.18696 2.44223 0.15464
