/* ** ** 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 56016.032696 0.000573 0.14512 0.01118 0.98485 0 17.40409 0.47267 13.98902 0.37992 2.52575 0.18216 2.02698 0.14617 56016.033839 0.000570 0.13961 0.01081 0.98985 0 18.60071 0.49961 14.45987 0.38837 2.59682 0.18856 2.01774 0.14646 56016.035022 0.000613 0.14017 0.01083 0.98113 0 17.26887 0.46443 13.58940 0.36541 2.42057 0.17527 1.90126 0.13764 56016.036226 0.000590 0.14561 0.01149 0.99510 0 16.88709 0.46944 13.20042 0.36687 2.45896 0.18164 1.92146 0.14187 56016.037357 0.000541 0.15869 0.01222 0.98396 0 17.48102 0.50097 13.68100 0.39204 2.77402 0.19826 2.16884 0.15498 56016.038425 0.000527 0.16584 0.01291 0.99451 0 16.84091 0.49411 13.15568 0.38595 2.79286 0.20138 2.18376 0.15747 56016.039484 0.000532 0.15795 0.01240 0.97826 0 17.69334 0.50813 13.78046 0.39572 2.79458 0.20414 2.17587 0.15898 56016.040838 0.000822 0.14672 0.00974 0.98944 0 17.15663 0.40001 13.36439 0.31159 2.51719 0.15643 1.96059 0.12184
