/* ** ** 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 55267.922767 0.000469 0.26018 0.00945 1.00000 0 50.96281 0.83567 46.84583 0.76816 13.25956 0.42983 12.18816 0.39510 55267.923688 0.000451 0.27218 0.00993 1.00000 0 50.65053 0.85148 46.51674 0.78198 13.78582 0.44618 12.66058 0.40976 55267.924573 0.000434 0.27616 0.01008 1.00000 0 51.96133 0.88001 47.72728 0.80831 14.34968 0.46418 13.18036 0.42636 55267.925458 0.000451 0.26850 0.00974 1.00000 0 51.52517 0.85932 47.32367 0.78924 13.83450 0.44564 12.70639 0.40930 55267.926373 0.000463 0.26220 0.00945 1.00000 0 51.71650 0.84913 47.50104 0.77991 13.56019 0.43498 12.45488 0.39953 55267.927287 0.000451 0.26546 0.00962 1.00000 0 52.05674 0.86227 47.81655 0.79203 13.81919 0.44537 12.69355 0.40910 55267.928213 0.000475 0.25701 0.00928 1.00000 0 51.30413 0.83957 47.12233 0.77113 13.18572 0.42430 12.11100 0.38971 55267.929119 0.000431 0.28275 0.01028 1.00000 0 51.45512 0.87997 47.25315 0.80811 14.54907 0.46694 13.36092 0.42881 55267.929984 0.000434 0.28679 0.01059 0.99333 0 50.20288 0.86605 46.10622 0.79538 14.39766 0.46992 13.22287 0.43158 55267.930849 0.000431 0.29059 0.01057 0.99329 0 50.43113 0.87425 46.31553 0.80290 14.65489 0.46885 13.45888 0.43058 55267.931758 0.000477 0.25397 0.00913 1.00000 0 51.67267 0.83430 47.45926 0.76627 13.12328 0.42140 12.05318 0.38704 55267.933135 0.000900 0.25908 0.00674 0.99678 0 52.07174 0.61117 47.82963 0.56138 13.49054 0.31345 12.39146 0.28791
