/* ** ** 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 54560.179571 0.000411 0.26208 0.00940 1.00000 0 58.72950 0.96095 53.78527 0.88009 15.39210 0.49149 14.10059 0.45020 54560.180381 0.000399 0.27371 0.00994 1.00000 0 56.83893 0.95825 52.48748 0.88478 15.55755 0.50014 14.37133 0.46194 54560.181168 0.000388 0.28208 0.01036 1.00000 0 57.78383 0.99088 52.39395 0.89841 16.29946 0.52918 14.77754 0.47979 54560.181949 0.000394 0.27418 0.00997 1.00000 0 57.59844 0.97072 53.34661 0.89902 15.79210 0.50871 14.62672 0.47117 54560.182846 0.000503 0.27745 0.00885 0.99673 0 58.40728 0.86619 53.73882 0.79689 16.20495 0.45751 14.91207 0.42105 54560.241372 0.000405 0.27026 0.00997 1.00000 0 57.45533 0.96989 52.03390 0.87833 15.52778 0.50916 14.06171 0.46107 54560.242212 0.000434 0.25023 0.00900 1.00000 0 58.19522 0.93885 52.83006 0.85227 14.56237 0.46798 13.22297 0.42493 54560.243074 0.000428 0.25870 0.00943 1.00000 0 56.54054 0.93122 51.51857 0.84851 14.62720 0.47569 13.32803 0.43344 54560.243939 0.000437 0.25384 0.00929 1.00000 0 56.18303 0.92171 51.20386 0.84003 14.26163 0.46670 12.99722 0.42533 54560.244793 0.000417 0.26110 0.00947 1.00000 0 57.85276 0.95752 52.70133 0.87226 15.10537 0.48744 13.76035 0.44403 54560.245629 0.000420 0.25992 0.00953 1.00000 0 57.30165 0.94412 52.20811 0.86019 14.89368 0.48761 13.56975 0.44427 54560.246480 0.000431 0.26550 0.00969 0.99329 0 55.42213 0.92272 50.48145 0.84046 14.71445 0.47800 13.40265 0.43538 54560.247330 0.000420 0.26254 0.00960 0.99310 0 57.06548 0.94266 51.99265 0.85887 14.98184 0.48900 13.64973 0.44552 54560.248172 0.000422 0.26099 0.00952 0.99315 0 57.16114 0.94247 52.07012 0.85853 14.91869 0.48543 13.58997 0.44219 54560.249289 0.000694 0.24404 0.00715 1.00000 0 57.30983 0.73754 52.20521 0.67184 13.98617 0.36827 12.74029 0.33546
