/* ** ** 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 59702.364931 0.000914 0.10834 0.00819 0.98101 0 12.84002 0.30254 11.80670 0.27821 1.39104 0.09989 1.27826 0.09176 59702.366733 0.000888 0.10833 0.00826 0.97394 0 13.07541 0.30991 12.14271 0.28781 1.41652 0.10272 1.31547 0.09539 59702.368458 0.000836 0.11324 0.00866 0.98270 0 13.17019 0.31926 12.23067 0.29649 1.49134 0.10814 1.38495 0.10043 59702.370203 0.000909 0.10827 0.00814 0.98089 0 12.84324 0.30334 11.92713 0.28170 1.39053 0.09932 1.29133 0.09223 59702.371959 0.000848 0.11462 0.00877 0.97611 0 12.92006 0.31473 11.99865 0.29228 1.48087 0.10738 1.37526 0.09972 59702.373666 0.000859 0.11079 0.00835 0.98316 0 13.23826 0.31685 12.29404 0.29425 1.46670 0.10476 1.36209 0.09729 59702.375460 0.000935 0.11373 0.00814 0.97214 0 13.41525 0.30528 12.45784 0.28350 1.52570 0.10355 1.41681 0.09616
