/* ** ** 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 55627.269071 0.000969 0.12389 0.00949 0.96716 0 13.36667 0.33458 9.77649 0.24438 1.65593 0.11988 1.21435 0.08785 55627.270926 0.000885 0.14058 0.01130 0.92810 0 13.05834 0.34918 9.48539 0.25362 1.83580 0.13912 1.33455 0.10114 55627.272552 0.000735 0.17520 0.01509 0.88583 0 12.72126 0.38460 9.14399 0.27643 2.22881 0.17969 1.60199 0.12913 55627.274150 0.000862 0.14936 0.01269 0.88255 0 12.90431 0.35687 9.23821 0.25550 1.92744 0.15481 1.37814 0.11073 55627.275903 0.000891 0.14913 0.01195 0.92208 0 12.58697 0.34515 8.99949 0.24676 1.87708 0.14132 1.34181 0.10101 55627.277735 0.000940 0.13730 0.01070 0.96615 0 12.62890 0.33490 9.02348 0.23928 1.73389 0.12711 1.23988 0.09088 55627.278970 0.000295 0.10018 0.01544 0.99020 0 13.38335 0.61655 9.59302 0.44194 1.34068 0.19716 0.96112 0.14137 55627.280214 0.000949 0.14358 0.01103 0.98780 0 11.97563 0.32514 8.50281 0.23085 1.71947 0.12359 1.22071 0.08773 55627.282240 0.001076 0.13391 0.00980 0.98387 0 12.38294 0.31117 8.77294 0.22045 1.65818 0.11392 1.17650 0.08083
