/* ** ** 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 55219.340912 0.000278 0.22631 0.01796 0.98958 0 20.12962 0.68087 18.49553 0.62556 4.55563 0.32708 4.18571 0.30053 55219.341482 0.000292 0.19461 0.01538 0.98020 0 22.49927 0.70879 20.55343 0.64742 4.37858 0.31744 4.00297 0.29008 55219.342089 0.000310 0.18336 0.01440 1.00000 0 21.68781 0.66899 20.18203 0.62254 3.97671 0.28722 3.70062 0.26728 55219.342668 0.000269 0.24228 0.01935 1.00000 0 18.95012 0.67284 17.63365 0.62609 4.59116 0.32853 4.27221 0.30570 55219.343221 0.000284 0.22566 0.01794 1.00000 0 19.32303 0.66063 17.98115 0.61475 4.36039 0.31307 4.05758 0.29133 55219.343834 0.000330 0.18783 0.01498 1.00000 0 19.60367 0.61659 18.24207 0.57376 3.68217 0.26986 3.42641 0.25112 55219.344456 0.000292 0.19728 0.01563 1.00000 0 21.24759 0.68262 19.77213 0.63522 4.19169 0.30354 3.90062 0.28247 55219.345032 0.000284 0.20929 0.01682 0.98980 0 20.67764 0.68302 19.24098 0.63556 4.32760 0.31716 4.02692 0.29513 55219.345605 0.000289 0.20880 0.01672 1.00000 0 20.18900 0.67075 18.78786 0.62420 4.21543 0.30710 3.92287 0.28578 55219.346164 0.000269 0.21792 0.01732 1.00000 0 21.04677 0.71001 19.53166 0.65883 4.58655 0.33015 4.25418 0.30623 55219.346705 0.000272 0.23582 0.01855 0.97872 0 20.03523 0.68821 18.58221 0.63829 4.72463 0.33439 4.38041 0.31002 55219.347234 0.000258 0.23940 0.01910 1.00000 0 20.27870 0.71436 18.75761 0.66074 4.85471 0.34763 4.49040 0.32158 55219.347772 0.000281 0.21284 0.01686 0.98969 0 21.09244 0.69588 19.36517 0.63885 4.48926 0.32320 4.12124 0.29666 55219.348337 0.000284 0.21843 0.01719 1.00000 0 20.26203 0.68066 18.73816 0.62942 4.42578 0.31507 4.09512 0.29154 55219.348907 0.000286 0.21279 0.01665 1.00000 0 21.05732 0.69172 19.13350 0.62848 4.48083 0.31822 4.07399 0.28931 55219.349465 0.000272 0.20763 0.01652 1.00000 0 22.15733 0.72943 20.17274 0.66405 4.60044 0.33318 4.19110 0.30350 55219.350018 0.000281 0.21060 0.01667 0.98969 0 21.61291 0.71011 19.67437 0.64647 4.55163 0.32783 4.14552 0.29864 55219.350553 0.000255 0.23502 0.01886 1.00000 0 20.90015 0.73044 19.16917 0.66988 4.91187 0.35478 4.49962 0.32499 55219.351054 0.000246 0.23514 0.01844 1.00000 0 22.06252 0.76468 20.21542 0.70062 5.18776 0.36504 4.76087 0.33497 55219.351595 0.000295 0.19552 0.01540 0.99020 0 21.73918 0.69335 20.03218 0.63892 4.25038 0.30601 3.91722 0.28198 55219.352162 0.000272 0.22467 0.01782 1.00000 0 20.39384 0.69711 18.82620 0.64350 4.58189 0.32790 4.22676 0.30245 55219.352952 0.000518 0.21133 0.01259 1.00000 0 20.00583 0.49870 18.42327 0.45919 4.22790 0.22872 3.89088 0.21051
