/* ** ** 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 56291.381766 0.001050 0.10390 0.00791 0.96970 0 11.71590 0.26935 10.73529 0.24680 1.21725 0.08840 1.11778 0.08114 56291.383213 0.000396 0.09074 0.01180 0.98540 0 11.88684 0.44243 10.80774 0.40224 1.07856 0.13435 0.98090 0.12220 56291.383907 0.000298 0.08687 0.01283 1.00000 0 12.35024 0.52449 11.19888 0.47557 1.07284 0.15173 0.97249 0.13753 56291.385209 0.001004 0.11005 0.00826 0.98559 0 11.60488 0.27501 10.58936 0.25095 1.27716 0.09092 1.16627 0.08301 56291.387203 0.000990 0.10506 0.00792 0.98246 0 12.35636 0.28458 11.32389 0.26077 1.29815 0.09314 1.18829 0.08525 56291.389136 0.000943 0.11945 0.00894 0.98160 0 11.51620 0.28309 10.49014 0.25784 1.37558 0.09727 1.25208 0.08854 56291.390987 0.000909 0.11876 0.00914 0.98089 0 11.79673 0.29108 10.76814 0.26571 1.40097 0.10212 1.27811 0.09314 56291.393508 0.001612 0.11591 0.00662 0.99102 0 11.90531 0.21992 10.88293 0.20102 1.37999 0.07460 1.26044 0.06813
