/* ** ** 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 59999.830680 0.000634 0.09916 0.00740 0.98174 0 20.38538 0.45665 18.70610 0.41904 2.02146 0.14390 1.85512 0.13204 59999.831956 0.000642 0.09531 0.00719 0.99550 0 20.29684 0.45001 18.76399 0.41602 1.93442 0.13952 1.78833 0.12898 59999.833169 0.000570 0.10283 0.00784 1.00000 0 21.00737 0.48673 19.42073 0.44997 2.16013 0.15684 1.99698 0.14499 59999.834372 0.000634 0.09624 0.00731 0.99543 0 20.28317 0.45205 18.75140 0.41791 1.95202 0.14173 1.80461 0.13102 59999.835912 0.000906 0.10147 0.00633 0.99346 0 20.35445 0.37929 18.78046 0.34994 2.06538 0.12287 1.90539 0.11335 60000.035666 0.000715 0.09172 0.00698 0.98785 0 19.10979 0.41624 17.51843 0.38156 1.75275 0.12780 1.60716 0.11716 60000.037011 0.000631 0.10266 0.00774 0.98624 0 19.47474 0.44445 18.01142 0.41105 1.99933 0.14360 1.84911 0.13281 60000.038250 0.000608 0.10814 0.00819 0.98571 0 19.10614 0.45066 17.67037 0.41679 2.06616 0.14879 1.91089 0.13761 60000.039506 0.000648 0.09959 0.00763 0.98661 0 19.27882 0.43819 17.83038 0.40527 1.92003 0.14045 1.77577 0.12990 60000.040732 0.000579 0.11543 0.00873 0.99500 0 18.69868 0.45506 17.29348 0.42086 2.15848 0.15449 1.99627 0.14288 60000.042000 0.000689 0.09978 0.00749 0.98319 0 18.39685 0.41736 17.01456 0.38600 1.83561 0.13138 1.69769 0.12151 60000.043241 0.000553 0.11929 0.00909 0.97906 0 19.17188 0.47576 17.73135 0.44001 2.28710 0.16470 2.11526 0.15232 60000.044462 0.000668 0.11102 0.00813 0.99567 0 18.31586 0.41952 16.93892 0.38798 2.03342 0.14138 1.88049 0.13075
