/* ** ** 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 56076.784182 0.000469 0.14084 0.01104 0.98765 0 19.04455 0.51541 17.28473 0.46775 2.68218 0.19732 2.43589 0.17925 56076.785137 0.000486 0.12846 0.00985 1.00000 0 20.25973 0.52468 18.31690 0.47431 2.60255 0.18780 2.35241 0.16968 56076.786127 0.000503 0.13240 0.01017 1.00000 0 19.02673 0.49650 17.26788 0.45054 2.51907 0.18194 2.28386 0.16497 56076.787139 0.000509 0.13073 0.00996 0.98864 0 19.19124 0.49677 17.45457 0.45181 2.50890 0.17978 2.28176 0.16350 56076.788181 0.000532 0.12845 0.01001 0.97826 0 18.71707 0.48057 16.84975 0.43262 2.40424 0.17692 2.16524 0.15934 56076.789295 0.000582 0.11813 0.00892 0.98010 0 19.10060 0.46743 17.15135 0.41970 2.25627 0.16124 2.02553 0.14476 56076.790487 0.000611 0.10796 0.00829 0.99052 0 19.30340 0.45664 17.33974 0.41019 2.08405 0.15231 1.87351 0.13695 56076.791624 0.000527 0.13163 0.01014 0.98901 0 18.59627 0.48682 16.69655 0.43702 2.44779 0.17726 2.19660 0.15908 56076.792660 0.000509 0.12269 0.00938 0.99432 0 20.82414 0.52284 18.49422 0.46431 2.55485 0.18458 2.27081 0.16403 56076.794139 0.000969 0.12427 0.00702 0.97910 0 19.84920 0.36918 17.70782 0.32933 2.46676 0.13149 2.20157 0.11735
