/* ** ** 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 56062.159237 0.000304 0.07133 0.01107 0.99048 0 18.31128 0.72067 12.92257 0.50462 1.30617 0.19613 0.92848 0.13840 56062.160307 0.000767 0.11513 0.00885 0.98113 0 18.06977 0.44217 13.14624 0.32110 2.08037 0.15166 1.51407 0.11033 56062.161861 0.000787 0.10955 0.00827 0.97794 0 19.55291 0.46291 13.62057 0.32242 2.14205 0.15349 1.49272 0.10694 56062.163470 0.000822 0.10549 0.00800 0.97887 0 19.35910 0.45099 13.46846 0.31373 2.04228 0.14728 1.42180 0.10253 56062.165079 0.000787 0.11287 0.00874 0.98897 0 18.37612 0.44686 12.84657 0.31238 2.07412 0.15255 1.44927 0.10659 56062.166583 0.000718 0.12291 0.00933 0.98790 0 18.98929 0.47738 13.18479 0.33145 2.33389 0.16719 1.62066 0.11611 56062.168192 0.000891 0.10296 0.00813 0.98377 0 17.87372 0.41862 12.31964 0.28850 1.84035 0.13870 1.26947 0.09560 56062.169888 0.000804 0.11146 0.00871 0.98561 0 18.36836 0.44416 12.70571 0.30724 2.04739 0.15222 1.41698 0.10531 56062.171806 0.001114 0.10206 0.00715 0.98961 0 17.70117 0.37108 12.26553 0.25712 1.80650 0.12082 1.25092 0.08368
