/* ** ** 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 55257.021042 0.000347 0.35382 0.01330 1.00000 0 52.72982 1.01034 46.67941 0.89447 18.65665 0.60308 16.51993 0.53399 55257.021728 0.000339 0.35384 0.01347 1.00000 0 53.28505 1.03378 47.46915 0.92066 18.85452 0.61774 16.79841 0.55040 55257.022428 0.000362 0.33200 0.01235 1.00000 0 53.13887 0.99014 47.93661 0.89321 17.64220 0.56819 15.91515 0.51257 55257.023163 0.000373 0.32433 0.01204 1.00000 0 52.68166 0.96595 47.52579 0.87141 17.08630 0.55143 15.41397 0.49746 55257.023889 0.000353 0.33096 0.01257 1.00000 0 53.78261 1.00597 48.52875 0.90770 17.79983 0.58836 16.06102 0.53088 55257.024604 0.000362 0.32506 0.01215 1.00000 0 53.76358 0.98992 48.54172 0.89378 17.47653 0.56846 15.77916 0.51325 55257.025321 0.000356 0.32952 0.01231 1.00000 0 54.14299 1.00184 48.86129 0.90412 17.84117 0.57910 16.10088 0.52261 55257.026019 0.000341 0.33816 0.01250 1.00000 0 55.32819 1.03372 49.93050 0.93287 18.70961 0.59661 16.88430 0.53840 55257.026707 0.000347 0.34662 0.01308 1.00000 0 52.60346 1.00818 47.46788 0.90975 18.23357 0.59277 16.45332 0.53490 55257.027387 0.000333 0.35063 0.01334 0.99130 0 54.31313 1.03451 49.02102 0.93371 19.04379 0.62723 17.18793 0.56610 55257.028062 0.000341 0.36023 0.01362 1.00000 0 51.50487 1.00079 46.47210 0.90300 18.55351 0.60192 16.74059 0.54310 55257.028750 0.000347 0.34851 0.01303 1.00000 0 52.89483 1.00566 47.73656 0.90759 18.43444 0.59371 16.63679 0.53582 55257.029465 0.000367 0.32983 0.01236 1.00000 0 52.37295 0.97062 47.27850 0.87620 17.27424 0.56272 15.59393 0.50798 55257.030185 0.000353 0.34209 0.01284 1.00000 0 52.52799 0.99817 47.40342 0.90079 17.96922 0.58145 16.21627 0.52472 55257.030877 0.000339 0.34848 0.01312 1.00000 0 53.64374 1.02337 48.40086 0.92335 18.69360 0.60679 16.86655 0.54748 55257.031563 0.000347 0.35193 0.01326 1.00000 0 51.95520 0.99906 46.86982 0.90128 18.28459 0.59257 16.49497 0.53457 55257.032257 0.000347 0.34626 0.01304 1.00000 0 52.63351 1.00397 47.49254 0.90591 18.22497 0.59157 16.44489 0.53379
