/* ** ** 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 59997.971948 0.000929 0.09435 0.00710 0.98442 0 16.50389 0.36375 13.35342 0.29400 1.55712 0.11202 1.25706 0.09043 59997.973802 0.000926 0.09155 0.00694 0.98125 0 16.83178 0.36679 13.71167 0.29873 1.54094 0.11185 1.25291 0.09096 59997.975703 0.000975 0.08331 0.00629 0.97626 0 17.63873 0.36517 14.36359 0.29736 1.46950 0.10669 1.19579 0.08682 59997.978279 0.001600 0.09183 0.00533 0.99234 0 16.39598 0.27400 13.46894 0.22507 1.50557 0.08365 1.23703 0.06872 59998.103473 0.000894 0.09291 0.00691 0.98706 0 15.44650 0.33539 14.07481 0.30559 1.43520 0.10208 1.30839 0.09304 59998.105360 0.000992 0.08527 0.00649 0.97085 0 15.15827 0.31628 13.85032 0.28899 1.29262 0.09459 1.18143 0.08645 59998.107119 0.000767 0.10876 0.00819 0.98491 0 15.36573 0.36287 13.99372 0.33045 1.67118 0.11951 1.52280 0.10890 59998.108899 0.001013 0.07864 0.00590 0.99143 0 15.88045 0.31943 14.44989 0.29064 1.24885 0.09033 1.13612 0.08217 59998.111196 0.001285 0.08296 0.00539 0.98423 0 16.03200 0.28487 14.59982 0.25942 1.33000 0.08317 1.21109 0.07573
