/* ** ** 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 57487.887769 0.000367 0.15358 0.01219 1.00000 0 21.64981 0.61866 19.89422 0.56850 3.32502 0.24619 3.05539 0.22623 57487.888495 0.000359 0.15808 0.01249 0.99194 0 21.81862 0.63046 20.04934 0.57934 3.44911 0.25369 3.16942 0.23312 57487.889166 0.000312 0.18871 0.01510 0.99074 0 21.01042 0.66077 19.30669 0.60719 3.96487 0.29163 3.64336 0.26798 57487.889823 0.000344 0.17312 0.01342 1.00000 0 21.08033 0.63337 19.37093 0.58201 3.64938 0.26078 3.35345 0.23963 57487.890506 0.000339 0.18538 0.01444 0.98291 0 20.48342 0.62965 18.82242 0.57859 3.79715 0.27172 3.48924 0.24968 57487.891218 0.000373 0.15853 0.01225 0.96899 0 21.81624 0.61726 20.04716 0.56721 3.45850 0.24876 3.17805 0.22859 57487.891984 0.000394 0.15673 0.01237 0.97794 0 20.35231 0.58218 18.70194 0.53497 3.18978 0.23462 2.93112 0.21559 57487.892760 0.000382 0.15812 0.01204 0.97727 0 21.37659 0.60238 19.64316 0.55353 3.38002 0.23900 3.10594 0.21962 57487.893802 0.000660 0.16067 0.00933 0.99148 0 21.67480 0.46326 19.91718 0.42569 3.48240 0.18798 3.20001 0.17274 57487.937072 0.001143 0.16288 0.01120 0.97713 0 21.13635 0.54209 8.11992 0.20826 3.44275 0.21960 1.32259 0.08436 57487.957382 0.000312 0.16895 0.01305 0.97222 0 24.26454 0.70826 22.49132 0.65651 4.09943 0.29305 3.79985 0.27163 57487.957969 0.000275 0.19973 0.01580 1.00000 0 22.46631 0.72775 20.82451 0.67456 4.48728 0.32377 4.15936 0.30011 57487.958534 0.000289 0.17482 0.01385 1.00000 0 24.15662 0.73712 22.39130 0.68325 4.22317 0.30886 3.91454 0.28629 57487.959185 0.000362 0.14601 0.01128 0.99200 0 23.54477 0.65016 21.82415 0.60265 3.43784 0.24805 3.18660 0.22992 57487.959980 0.000434 0.15052 0.01039 1.00000 0 23.77063 0.59411 22.03351 0.55069 3.57794 0.23026 3.31646 0.21343
