/* ** ** 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 54482.147049 0.000229 0.16305 0.01274 0.98734 0 49.51977 1.42495 30.92906 0.88999 8.07439 0.58633 5.04380 0.36618 54482.147555 0.000278 0.16591 0.01272 1.00000 0 46.64679 1.37394 25.24801 0.74217 7.73902 0.54778 4.21733 0.29792 54482.148128 0.000295 0.18049 0.01416 0.99020 0 42.16767 1.30029 21.68718 0.66867 7.61070 0.54890 3.91316 0.28223 54482.148721 0.000298 0.16734 0.01295 1.00000 0 45.39701 1.34409 23.15990 0.68568 7.59674 0.54300 3.87422 0.27687 54482.149306 0.000286 0.16452 0.01312 0.97980 0 47.64958 1.41116 24.32326 0.72029 7.83925 0.58066 3.99978 0.29623 54482.149882 0.000289 0.16845 0.01309 0.98000 0 47.16706 1.38560 24.03227 0.70591 7.94538 0.57156 4.05339 0.29158 54482.150458 0.000286 0.17893 0.01385 1.00000 0 44.83451 1.36986 22.71708 0.69402 8.02227 0.57049 4.07122 0.28947 54482.151016 0.000272 0.18603 0.01500 0.96809 0 45.54065 1.42123 22.94549 0.71601 8.47205 0.62995 4.26560 0.31715 54482.151696 0.000402 0.15786 0.01087 0.98774 0 48.71402 1.20927 24.32511 0.60387 7.69020 0.49370 3.84099 0.24661 54482.215331 0.000208 0.14491 0.01116 1.00000 0 41.26327 1.12711 38.29017 1.04590 5.97939 0.43058 5.54857 0.39955 54482.215716 0.000177 0.16685 0.01300 1.00000 0 41.86461 1.23650 38.83260 1.14696 6.98514 0.50367 6.48003 0.46724 54482.216084 0.000191 0.16306 0.01273 1.00000 0 40.35881 1.17887 36.74569 1.07326 6.58082 0.47637 5.99228 0.43376 54482.216451 0.000177 0.17472 0.01369 0.98361 0 40.68073 1.21921 37.73077 1.13081 7.10770 0.51449 6.59151 0.47713 54482.216824 0.000197 0.15346 0.01176 1.00000 0 42.14208 1.18838 38.44511 1.08413 6.46722 0.46094 5.89828 0.42038 54482.217215 0.000194 0.14971 0.01158 1.00000 0 42.91986 1.19963 39.36973 1.10030 6.42570 0.46343 5.89973 0.42539 54482.217617 0.000208 0.14321 0.01112 1.00000 0 41.81150 1.13753 38.36013 1.04361 5.98790 0.43533 5.49582 0.39936 54482.218008 0.000182 0.16469 0.01256 1.00000 0 42.42942 1.23326 38.73979 1.12593 6.98749 0.49290 6.39158 0.45083 54482.218370 0.000179 0.16780 0.01304 1.00000 0 41.56647 1.22531 38.18574 1.12557 6.97480 0.50161 6.40783 0.46083 54482.218720 0.000171 0.17993 0.01412 0.98305 0 41.31455 1.25379 37.91575 1.15057 7.43369 0.53798 6.81880 0.49359 54482.219165 0.000275 0.17640 0.01063 1.00000 0 42.99162 0.99966 39.88234 0.92736 7.58385 0.42150 7.03538 0.39101
