/* ** ** 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 55600.364273 0.000312 0.09996 0.02323 0.98148 0 4.85700 0.34306 3.93163 0.27765 0.48550 0.10751 0.39191 0.08675 55600.364945 0.000359 0.07876 0.01857 0.99194 0 4.90955 0.31409 4.08184 0.26114 0.38667 0.08777 0.32146 0.07296 55600.365674 0.000370 0.08930 0.02113 0.95312 0 4.38050 0.29372 3.62924 0.24334 0.39117 0.08879 0.32409 0.07356 55600.366666 0.000622 0.13348 0.02044 0.97209 0 4.26370 0.22275 3.53443 0.18465 0.56910 0.08194 0.47170 0.06792 55600.367636 0.000347 0.10673 0.02450 0.98333 0 4.03078 0.28759 3.34036 0.23833 0.43021 0.09388 0.35653 0.07780 55600.368677 0.000694 0.10783 0.01626 0.98333 0 4.71339 0.22415 3.89163 0.18507 0.50825 0.07274 0.41997 0.06011 55600.369777 0.000405 0.08860 0.02097 0.95714 0 4.01773 0.26935 3.33061 0.22328 0.35597 0.08080 0.29507 0.06698 55600.370680 0.000498 0.06860 0.01608 0.94186 0 4.29183 0.25010 3.55822 0.20735 0.29440 0.06682 0.24407 0.05540 55600.371475 0.000298 0.10471 0.02461 0.98058 0 4.56921 0.33125 3.78854 0.27465 0.47844 0.10698 0.39670 0.08870 55600.372213 0.000440 0.07797 0.01767 0.96711 0 4.42840 0.27110 3.67052 0.22471 0.34529 0.07535 0.28619 0.06245 55600.372992 0.000339 0.09435 0.02237 0.94017 0 4.59645 0.31549 3.80978 0.26149 0.43369 0.09844 0.35945 0.08159 55600.374016 0.000686 0.13322 0.01998 0.94095 0 4.12728 0.21218 3.42129 0.17589 0.54985 0.07745 0.45579 0.06420 55600.375199 0.000498 0.10402 0.01932 0.97093 0 4.45141 0.25417 3.69034 0.21071 0.46304 0.08185 0.38387 0.06786
