/* ** ** 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 58517.200215 0.000460 0.14300 0.01122 0.99371 0 23.84283 0.65453 17.33840 0.47545 3.40943 0.25055 2.47841 0.18203 58517.201103 0.000428 0.16106 0.01293 0.99324 0 24.38320 0.71920 16.32904 0.48140 3.92726 0.29328 2.62512 0.19598 58517.201968 0.000437 0.16637 0.01300 0.98013 0 23.66132 0.69097 16.05776 0.46886 3.93652 0.28528 2.67083 0.19352 58517.203294 0.000888 0.16166 0.00891 0.97171 0 23.69741 0.48231 16.33400 0.33235 3.83081 0.19616 2.64286 0.13530 58517.265376 0.000350 0.16798 0.01297 1.00000 0 22.13186 0.65182 19.56046 0.57603 3.71781 0.26530 3.28923 0.23466 58517.266108 0.000382 0.15417 0.01176 1.00000 0 22.09781 0.62511 19.71757 0.55780 3.40690 0.24137 3.04042 0.21541 58517.266843 0.000353 0.15833 0.01222 1.00000 0 22.90796 0.65769 20.53575 0.58958 3.62692 0.25991 3.25134 0.23300 58517.267563 0.000367 0.15458 0.01206 1.00000 0 22.31256 0.63571 20.00172 0.56987 3.44898 0.25050 3.09181 0.22456 58517.268269 0.000339 0.17569 0.01365 0.99145 0 21.71110 0.65053 19.46352 0.58319 3.81434 0.27334 3.41951 0.24505 58517.268946 0.000339 0.17186 0.01319 0.99145 0 22.45509 0.66393 20.13136 0.59522 3.85910 0.27341 3.45979 0.24512 58517.269664 0.000379 0.15440 0.01189 0.99237 0 22.04331 0.62061 19.76122 0.55636 3.40358 0.24391 3.05125 0.21866 58517.270376 0.000333 0.18959 0.01483 0.99130 0 20.47278 0.64287 18.35242 0.57629 3.88150 0.27815 3.47950 0.24935 58517.271076 0.000367 0.15918 0.01220 0.99213 0 22.24816 0.63261 19.94336 0.56708 3.54149 0.25202 3.17461 0.22591 58517.271843 0.000399 0.14305 0.01088 1.00000 0 22.56595 0.61277 20.22848 0.54930 3.22808 0.22928 2.89371 0.20553 58517.272583 0.000341 0.17434 0.01331 0.98305 0 22.32192 0.66097 20.01072 0.59253 3.89150 0.27381 3.48856 0.24545 58517.273255 0.000330 0.18228 0.01404 1.00000 0 21.79546 0.66976 19.53874 0.60041 3.97282 0.28059 3.56150 0.25154
