/* ** ** 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 59377.212890 0.000547 0.11650 0.00920 0.97884 0 19.28517 0.47808 17.85837 0.44271 2.24675 0.16854 2.08000 0.15604 59377.213908 0.000472 0.13703 0.01058 0.98773 0 19.53566 0.51885 17.93941 0.47644 2.67693 0.19415 2.45800 0.17829 59377.214904 0.000524 0.12240 0.00927 0.99448 0 19.84144 0.49847 18.06006 0.45367 2.42863 0.17349 2.20938 0.15783 59377.216000 0.000573 0.11063 0.00853 0.98990 0 19.84511 0.47690 18.11147 0.43521 2.19539 0.16092 2.00388 0.14685 59377.217103 0.000530 0.11732 0.00904 0.98907 0 20.18623 0.50369 18.46906 0.46087 2.36833 0.17267 2.16427 0.15782 59377.218185 0.000553 0.11710 0.00880 0.98429 0 19.95170 0.48727 18.14582 0.44314 2.33632 0.16606 2.12329 0.15091 59377.219250 0.000512 0.12496 0.00954 0.98870 0 19.65112 0.49764 18.12873 0.45904 2.45554 0.17680 2.26693 0.16319 59377.220647 0.000885 0.11750 0.00700 0.99673 0 19.40740 0.37647 17.87953 0.34683 2.28038 0.12850 2.10203 0.11845
