/* ** ** 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 58816.276013 0.000446 0.15233 0.01175 0.97403 0 20.69582 0.57583 17.35480 0.48280 3.15263 0.22688 2.64364 0.19023 58816.276959 0.000501 0.12867 0.00991 0.98844 0 21.24973 0.54924 17.90560 0.46278 2.73420 0.19832 2.30465 0.16717 58816.277995 0.000535 0.12149 0.00923 0.98919 0 21.19434 0.52888 17.94395 0.44778 2.57480 0.18481 2.17786 0.15631 58816.278952 0.000422 0.15481 0.01185 0.99315 0 21.20914 0.59604 17.88173 0.50250 3.28345 0.23381 2.76551 0.19691 58816.279847 0.000472 0.13759 0.01059 0.97546 0 21.44034 0.56386 18.10894 0.47624 2.95004 0.21343 2.49119 0.18023 58816.280784 0.000466 0.13782 0.01049 0.99379 0 21.46219 0.56892 18.08695 0.47944 2.95793 0.21113 2.49372 0.17801 58816.281661 0.000411 0.16109 0.01248 0.98592 0 20.90314 0.59876 17.58078 0.50356 3.36735 0.24228 2.83247 0.20381 58816.282540 0.000469 0.13520 0.01032 0.96914 0 22.31360 0.57867 18.79308 0.48734 3.01675 0.21649 2.53853 0.18219 58816.283854 0.000845 0.13870 0.00786 0.98875 0 21.61599 0.42359 18.31082 0.35882 2.99811 0.15942 2.53994 0.13506
