/* ** ** 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 57928.879685 0.000553 0.14521 0.01125 0.99476 0 15.91596 0.43515 14.25284 0.38966 2.31111 0.16752 2.06925 0.14998 57928.880796 0.000558 0.14073 0.01079 0.97409 0 16.60879 0.44124 14.95202 0.39721 2.33733 0.16803 2.10458 0.15129 57928.881922 0.000567 0.13562 0.01053 0.98980 0 16.67997 0.44099 14.96600 0.39565 2.26220 0.16514 2.02788 0.14804 57928.883067 0.000579 0.13834 0.01064 0.98500 0 16.19862 0.43063 14.48649 0.38510 2.24092 0.16177 2.00208 0.14451 57928.884231 0.000584 0.14389 0.01101 0.98020 0 15.52263 0.41996 13.93372 0.37696 2.23354 0.15991 2.00461 0.14351 57928.885455 0.000639 0.12033 0.00933 0.98643 0 16.62081 0.41498 14.83725 0.37042 2.00003 0.14682 1.78625 0.13110 57928.886710 0.000616 0.12742 0.00976 0.99061 0 16.34312 0.41752 14.67070 0.37476 2.08246 0.15032 1.86924 0.13493 57928.887902 0.000576 0.13728 0.01043 0.97487 0 16.66608 0.43749 14.95552 0.39259 2.28789 0.16311 2.05239 0.14632 57928.889034 0.000556 0.14645 0.01139 0.97917 0 15.91807 0.43454 14.22529 0.38829 2.33125 0.16972 2.08460 0.15173 57928.890261 0.000671 0.13985 0.01004 0.99569 0 15.88088 0.39843 14.00389 0.35133 2.22098 0.14945 1.95890 0.13180
