/* ** ** 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 56350.357545 0.001021 0.12535 0.00955 0.98867 0 11.21544 0.28357 9.08177 0.22921 1.40585 0.10105 1.13603 0.08140 56350.358925 0.000359 0.08166 0.01285 1.00000 0 11.66863 0.48700 9.46764 0.39510 0.95282 0.14455 0.77322 0.11722 56350.360282 0.000998 0.12728 0.00971 0.98841 0 11.23328 0.28694 9.10858 0.23265 1.42973 0.10278 1.15960 0.08337 56350.361607 0.000327 0.09741 0.01480 0.97345 0 11.29503 0.50335 9.16246 0.40828 1.10027 0.15976 0.89155 0.12948 56350.362507 0.000573 0.11450 0.01242 0.97475 0 10.73741 0.37203 8.65363 0.29983 1.22946 0.12635 0.99105 0.10185 56350.363401 0.000321 0.10891 0.01622 0.97297 0 10.52295 0.49074 8.51903 0.39723 1.14605 0.16209 0.92747 0.13116 56350.364660 0.000938 0.14197 0.01094 0.98457 0 10.73209 0.28899 8.72464 0.23492 1.52364 0.10999 1.23928 0.08946 56350.366656 0.001059 0.11776 0.00906 0.98087 0 11.26082 0.27714 9.29035 0.22860 1.32612 0.09668 1.09250 0.07964 56350.368103 0.000388 0.11006 0.01463 0.96269 0 10.78774 0.44843 8.91885 0.37069 1.18732 0.14995 0.98579 0.12450 56350.368957 0.000466 0.10906 0.01332 0.98758 0 10.74569 0.41034 8.78398 0.33538 1.17192 0.13593 0.95700 0.11095
