/* ** ** 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 57484.213846 0.000469 0.13967 0.01060 1.00000 0 19.49020 0.52313 17.71874 0.47552 2.72217 0.19325 2.47455 0.17567 57484.214720 0.000399 0.16115 0.01260 0.99275 0 19.74271 0.57062 17.81061 0.51477 3.18160 0.23105 2.87221 0.20845 57484.215562 0.000443 0.14087 0.01082 0.99346 0 20.85212 0.56011 18.57654 0.49896 2.93754 0.21128 2.61375 0.18797 57484.216439 0.000434 0.14278 0.01097 0.98000 0 21.36648 0.57215 19.04327 0.50993 3.05062 0.21968 2.71771 0.19570 57484.217324 0.000451 0.13563 0.01074 0.98718 0 20.84021 0.55708 18.49519 0.49440 2.82665 0.21059 2.50857 0.18690 57484.218184 0.000408 0.15315 0.01213 0.98582 0 20.54494 0.57941 18.23103 0.51415 3.14647 0.23289 2.79218 0.20666 57484.219052 0.000460 0.13720 0.01036 0.99371 0 20.80475 0.54968 18.48104 0.48828 2.85432 0.20183 2.53587 0.17931 57484.219958 0.000446 0.14474 0.01115 0.98701 0 20.17792 0.54717 17.96106 0.48704 2.92055 0.21053 2.60057 0.18751 57484.220869 0.000466 0.13245 0.01005 1.00000 0 21.10127 0.54916 18.80094 0.48928 2.79481 0.19921 2.49122 0.17755 57484.221775 0.000440 0.14343 0.01113 0.98684 0 20.56754 0.55896 18.40276 0.50012 2.94992 0.21439 2.63804 0.19169 57484.222701 0.000486 0.12446 0.00969 0.99405 0 21.06059 0.53927 18.75469 0.48021 2.62130 0.19272 2.33477 0.17168 57484.223748 0.000561 0.13810 0.00985 0.98969 0 19.29540 0.47818 17.23066 0.42700 2.66467 0.17831 2.38224 0.15941
