/* ** ** 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 56413.942529 0.000480 0.15012 0.01152 0.96386 0 17.86917 0.48585 16.50202 0.44867 2.68253 0.19248 2.47721 0.17775 56413.943530 0.000521 0.12757 0.00985 0.98889 0 18.66435 0.47766 17.26527 0.44186 2.38099 0.17339 2.20247 0.16039 56413.944549 0.000498 0.14159 0.01097 0.97674 0 17.98343 0.48374 16.57286 0.44579 2.54636 0.18494 2.34549 0.17036 56413.945512 0.000466 0.14512 0.01117 0.96894 0 19.04290 0.51277 17.54271 0.47237 2.76356 0.19923 2.54798 0.18368 56413.946459 0.000480 0.14027 0.01080 1.00000 0 18.46593 0.49629 16.94385 0.45537 2.59018 0.18682 2.37901 0.17155 56413.947413 0.000475 0.13959 0.01080 0.98780 0 19.31301 0.51492 17.54821 0.46780 2.69581 0.19575 2.44822 0.17775 56413.948397 0.000509 0.12959 0.00976 0.98295 0 19.35987 0.49345 17.90003 0.45623 2.50877 0.17782 2.31926 0.16438 56413.949419 0.000512 0.13478 0.01038 0.97740 0 18.30908 0.47930 16.88772 0.44206 2.46762 0.17881 2.27444 0.16482 56413.950434 0.000503 0.13690 0.01057 0.99425 0 17.96062 0.47682 16.61343 0.44106 2.45887 0.17818 2.27444 0.16482 56413.951427 0.000489 0.13743 0.01048 0.98817 0 18.95496 0.50023 17.46687 0.46097 2.60489 0.18638 2.40075 0.17178 56413.952393 0.000477 0.13998 0.01068 0.99394 0 18.87940 0.50578 17.31718 0.46391 2.64277 0.18871 2.42556 0.17320 56413.953389 0.000518 0.12655 0.00972 1.00000 0 18.88862 0.48267 17.36082 0.44362 2.39038 0.17320 2.19820 0.15929 56413.954413 0.000506 0.13080 0.01021 0.98857 0 18.59370 0.48445 17.19873 0.44810 2.43196 0.17886 2.24950 0.16544 56413.955570 0.000651 0.14100 0.00908 0.98667 0 19.40182 0.43577 17.94635 0.40308 2.73566 0.16515 2.53044 0.15276
