/* ** ** 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 54232.158859 0.000761 0.12051 0.00928 0.97719 0 13.92696 0.34592 12.66135 0.31446 1.67834 0.12233 1.52610 0.11122 54232.160398 0.000778 0.12066 0.00917 0.99257 0 13.47225 0.33458 12.34972 0.30669 1.62552 0.11673 1.48912 0.10694 54232.161871 0.000694 0.13716 0.01040 0.98333 0 13.54878 0.35581 12.32194 0.32359 1.85834 0.13220 1.69057 0.12026 54232.163439 0.000874 0.11026 0.00850 0.98344 0 13.05707 0.31128 11.92413 0.28427 1.43968 0.10558 1.31486 0.09641 54232.165094 0.000781 0.11885 0.00900 0.99259 0 13.66411 0.33813 12.46830 0.30853 1.62392 0.11623 1.48240 0.10609 54232.166697 0.000822 0.10874 0.00834 0.99648 0 13.92135 0.33105 12.73574 0.30285 1.51379 0.11031 1.38589 0.10100 54232.168491 0.000972 0.11992 0.00802 0.98172 0 14.14708 0.30709 12.95452 0.28118 1.69650 0.10739 1.55247 0.09828 54232.225469 0.000706 0.12529 0.00939 0.97131 0 14.75296 0.36636 13.49314 0.33507 1.84840 0.13070 1.69058 0.11954 54232.226930 0.000755 0.12210 0.00930 0.98467 0 13.80903 0.34498 12.61240 0.31505 1.68606 0.12135 1.53958 0.11081 54232.228437 0.000752 0.11811 0.00916 0.98846 0 14.03915 0.34715 12.88149 0.31852 1.65819 0.12189 1.52145 0.11184 54232.229980 0.000790 0.11966 0.00906 0.98535 0 13.51056 0.33321 12.34072 0.30435 1.61666 0.11567 1.47709 0.10568 54232.231484 0.000715 0.12855 0.00969 0.99190 0 13.87622 0.35348 12.73284 0.32435 1.78373 0.12655 1.63676 0.11613 54232.233009 0.000804 0.11062 0.00840 0.97122 0 14.44941 0.34005 13.25863 0.31203 1.59844 0.11543 1.46670 0.10591 54232.234954 0.001140 0.11608 0.00726 0.97716 0 14.49637 0.28662 13.24030 0.26177 1.68267 0.09990 1.53685 0.09125
