/* ** ** 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 59936.253551 0.000521 0.09913 0.00760 0.98889 0 24.35534 0.54875 22.19707 0.50011 2.41445 0.17686 2.19964 0.16109 59936.254555 0.000483 0.10229 0.00760 1.00000 0 25.75139 0.58787 23.45363 0.53539 2.63420 0.18627 2.39920 0.16965 59936.255553 0.000515 0.09765 0.00731 0.98876 0 25.56773 0.56820 23.21057 0.51577 2.49658 0.17856 2.26418 0.16196 59936.256633 0.000564 0.09201 0.00695 0.97949 0 24.69812 0.53404 22.42442 0.48485 2.27236 0.16454 2.06130 0.14922 59936.257721 0.000524 0.09854 0.00740 0.98895 0 24.75123 0.55443 22.49664 0.50386 2.43899 0.17491 2.21504 0.15885 59936.258785 0.000541 0.09396 0.00704 0.97861 0 25.51522 0.55741 23.01671 0.50281 2.39748 0.17194 2.16662 0.15538 59936.259902 0.000576 0.08700 0.00642 0.98995 0 25.87369 0.54159 23.37555 0.48929 2.25088 0.15917 2.03384 0.14381 59936.261491 0.001013 0.09250 0.00504 0.98857 0 26.13794 0.41149 23.47198 0.36948 2.41785 0.12619 2.17204 0.11337
