/* ** ** 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 55200.204032 0.000472 0.24768 0.00896 1.00000 0 52.70289 0.84216 49.11965 0.78490 13.05319 0.42376 12.16221 0.39488 55200.204926 0.000422 0.27862 0.01006 1.00000 0 52.87530 0.89421 49.23227 0.83253 14.73186 0.47008 13.71785 0.43770 55200.205782 0.000434 0.27343 0.00993 1.00000 0 51.87695 0.87499 48.52076 0.81838 14.18485 0.45647 13.26714 0.42693 55200.206642 0.000425 0.26886 0.00977 0.99320 0 53.97943 0.89866 50.46682 0.84017 14.51308 0.46893 13.56953 0.43844 55200.207515 0.000448 0.26126 0.00951 1.00000 0 52.37362 0.86766 48.79511 0.80836 13.68335 0.44351 12.74993 0.41321 55200.208404 0.000440 0.26435 0.00956 0.99342 0 53.44422 0.88340 49.72096 0.82178 14.12797 0.45442 13.14548 0.42284 55200.209292 0.000448 0.28795 0.00995 0.99662 0 52.96377 0.86738 49.40285 0.80905 15.25117 0.46428 14.22315 0.43295 55200.273305 0.000376 0.28895 0.01057 1.00000 0 56.44083 0.97897 52.67263 0.91356 16.30845 0.52504 15.22806 0.49023 55200.274106 0.000425 0.26482 0.00968 1.00000 0 54.26887 0.89923 50.90294 0.84346 14.37165 0.46843 13.48028 0.43938 55200.274928 0.000396 0.27380 0.01000 1.00000 0 56.11574 0.94844 52.63651 0.88963 15.36445 0.49724 14.41185 0.46641 55200.275857 0.000532 0.27096 0.00869 1.00000 0 54.33416 0.80354 50.96475 0.75371 14.72255 0.41896 13.80957 0.39298
