/* ** ** 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 57053.002760 0.000436 0.17022 0.02670 0.96559 1 20.17183 1.21252 3.88503 0.23353 3.43368 0.49745 0.66045 0.09568 57053.004370 0.000660 0.13460 0.01034 0.97807 0 22.66434 0.59068 13.25576 0.34546 3.05062 0.22040 1.78155 0.12875 57053.005606 0.000576 0.15208 0.01184 0.96985 0 22.74704 0.63689 13.38702 0.37463 3.45931 0.25141 2.03772 0.14804 57053.006792 0.000611 0.14904 0.01153 0.97630 0 21.59836 0.60016 12.86353 0.35737 3.21898 0.23234 1.91809 0.13841 57053.007999 0.000596 0.14250 0.01079 0.98544 0 23.44845 0.62819 13.94013 0.37342 3.34138 0.23675 1.98437 0.14055 57053.009121 0.000527 0.16189 0.01260 0.99451 0 22.62775 0.66006 13.50349 0.39383 3.66310 0.26430 2.18302 0.15752 57053.010206 0.000558 0.14835 0.01154 0.97927 0 23.36190 0.64881 14.03573 0.38968 3.46572 0.25183 2.08084 0.15117 57053.011297 0.000532 0.15737 0.01268 0.99457 0 22.14797 0.64273 13.32632 0.38665 3.48538 0.26199 2.09861 0.15775 57053.012319 0.000489 0.17026 0.01320 0.98817 0 22.78729 0.67558 13.98235 0.41446 3.87977 0.27801 2.37709 0.17037 57053.013346 0.000538 0.16092 0.01234 0.99462 0 22.93244 0.64462 14.02690 0.39424 3.69022 0.26323 2.25832 0.16096
