/* ** ** 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 58800.675273 0.000483 0.14833 0.01174 0.97605 0 24.69532 0.68146 16.95431 0.45814 3.66296 0.27180 2.42451 0.17489 58800.676207 0.000451 0.16315 0.01286 1.00000 0 24.15217 0.71239 15.38121 0.45330 3.94048 0.28811 2.50992 0.18348 58800.677191 0.000532 0.14429 0.01119 0.97283 0 24.53240 0.66866 15.23211 0.41518 3.53981 0.25705 2.19760 0.15958 58800.678236 0.000512 0.15770 0.01262 0.97740 0 22.71048 0.65654 14.15433 0.40917 3.58148 0.26717 2.23165 0.16646 58800.679266 0.000518 0.14293 0.01106 0.98883 0 25.19565 0.68731 15.62521 0.42613 3.60124 0.26084 2.23375 0.16178 58800.680296 0.000512 0.12964 0.01019 0.99435 0 27.41902 0.72098 16.99998 0.44701 3.55467 0.26331 2.20397 0.16329 58800.681277 0.000469 0.15288 0.01167 0.98765 0 26.46370 0.74311 16.40851 0.46071 4.04572 0.28724 2.50529 0.17788 58800.682206 0.000460 0.15442 0.01204 0.98742 0 26.09271 0.73896 16.23958 0.45989 4.02916 0.29262 2.50555 0.18194 58800.683108 0.000443 0.16294 0.01272 0.98693 0 25.96909 0.75593 16.06701 0.46766 4.23152 0.30652 2.61837 0.18964 58800.684463 0.000911 0.14710 0.00834 0.99683 0 26.69177 0.53503 16.40558 0.32884 3.92639 0.20828 2.41328 0.12802
