/* ** ** 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 57548.486723 0.000315 0.27824 0.00999 1.00000 0 71.65674 1.20551 66.13161 1.11248 19.93749 0.63245 18.40204 0.58368 57548.487363 0.000324 0.26542 0.00957 1.00000 0 73.37134 1.21691 66.83727 1.10853 19.47430 0.62308 17.73457 0.56735 57548.487999 0.000312 0.27556 0.01002 1.00000 0 72.08618 1.21722 66.70676 1.12638 19.86377 0.63966 18.38070 0.59191 57548.488621 0.000310 0.27835 0.01013 1.00000 0 71.71530 1.22143 66.43688 1.13153 19.96216 0.64216 18.49292 0.59490 57548.489223 0.000292 0.30322 0.01110 1.00000 0 71.12939 1.26321 64.85262 1.15164 21.56774 0.69073 19.66726 0.62972 57548.489825 0.000310 0.28322 0.01031 1.00000 0 70.85589 1.21425 65.50626 1.12257 20.06774 0.64456 18.54909 0.59578 57548.490436 0.000301 0.28358 0.01024 1.00000 0 74.10086 1.26579 67.88217 1.15950 21.01353 0.66894 19.25171 0.61284 57548.491040 0.000304 0.28934 0.01051 1.00000 0 70.79164 1.22135 65.58050 1.13145 20.48307 0.65484 18.97527 0.60664 57548.491648 0.000304 0.28348 0.01023 1.00000 0 72.52791 1.23890 67.18977 1.14772 20.56025 0.65369 19.04698 0.60558 57548.492264 0.000312 0.27920 0.01011 1.00000 0 71.33038 1.21182 66.07584 1.12255 19.91524 0.63669 18.44818 0.58979 57548.492892 0.000315 0.27463 0.00996 1.00000 0 71.64209 1.20743 66.36847 1.11855 19.67542 0.63163 18.22712 0.58514 57548.493526 0.000318 0.27402 0.00993 1.00000 0 71.14649 1.19860 65.90994 1.11037 19.49558 0.62532 18.06032 0.57928 57548.494160 0.000315 0.27665 0.01002 1.00000 0 71.85356 1.21519 65.92329 1.11486 19.87808 0.63650 18.22379 0.58351 57548.494799 0.000324 0.26492 0.00953 1.00000 0 72.58833 1.20234 67.16758 1.11255 19.22984 0.61424 17.78823 0.56819 57548.495447 0.000324 0.27109 0.00976 1.00000 0 70.96721 1.18433 65.74458 1.09717 19.23873 0.61336 17.82293 0.56822 57548.496084 0.000312 0.28047 0.01017 1.00000 0 71.16199 1.20602 65.92896 1.11733 19.95857 0.64018 18.49087 0.59311 57548.496703 0.000307 0.28990 0.01052 1.00000 0 69.90501 1.20755 64.76398 1.11874 20.26543 0.64708 18.77507 0.59950 57548.497464 0.000454 0.28004 0.00841 1.00000 0 71.06225 0.99954 65.83285 0.92598 19.90004 0.52782 18.43559 0.48898
