/* ** ** 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 56287.120433 0.000298 0.06961 0.01009 1.00000 0 15.40497 0.57287 14.24927 0.52986 1.07234 0.15016 0.99194 0.13890 56287.121032 0.000301 0.07151 0.01059 0.99038 0 14.87066 0.56834 13.67775 0.52272 1.06335 0.15209 0.97698 0.13970 56287.121662 0.000330 0.06710 0.01032 0.99123 0 13.83289 0.51922 12.86690 0.48295 0.92824 0.13848 0.86325 0.12879 56287.122962 0.000969 0.08319 0.00641 0.98507 0 15.14308 0.31515 14.08887 0.29321 1.25982 0.09350 1.17212 0.08699 56287.125025 0.001094 0.07586 0.00560 0.99206 0 15.08093 0.29657 14.03112 0.27593 1.14397 0.08132 1.06434 0.07566 56287.127094 0.000975 0.08531 0.00641 0.98220 0 15.01773 0.31266 13.97107 0.29087 1.28113 0.09255 1.19185 0.08610 56287.129125 0.001056 0.08076 0.00606 0.96986 0 14.83145 0.29875 13.79982 0.27797 1.19773 0.08652 1.11442 0.08050 56287.131402 0.001221 0.09179 0.00596 0.98578 0 14.95027 0.27939 13.91098 0.25997 1.37230 0.08535 1.27690 0.07942
