/* ** ** 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 59136.963114 0.000463 0.29050 0.01053 1.00000 0 46.49630 0.79974 42.90377 0.73793 13.50728 0.43114 12.46114 0.39773 59136.964014 0.000437 0.30503 0.01115 1.00000 0 47.35055 0.83662 43.20703 0.76336 14.44342 0.46228 13.16998 0.42148 59136.964887 0.000437 0.31021 0.01136 1.00000 0 46.23118 0.82546 42.53496 0.75940 14.34120 0.45852 13.19651 0.42189 59136.965776 0.000451 0.29474 0.01072 1.00000 0 46.99654 0.81590 43.37865 0.75307 13.85170 0.44263 12.78639 0.40857 59136.966687 0.000460 0.29183 0.01060 1.00000 0 46.36786 0.80192 42.97772 0.74329 13.53167 0.43214 12.54232 0.40055 59136.967570 0.000422 0.31773 0.01165 1.00000 0 46.26514 0.83447 42.88393 0.77349 14.69987 0.46939 13.62554 0.43509 59136.968484 0.000492 0.27406 0.00996 1.00000 0 46.04183 0.77556 42.42479 0.71461 12.61830 0.40645 11.62870 0.37456 59136.969419 0.000443 0.31423 0.01157 1.00000 0 44.89889 0.80790 41.23275 0.74188 14.10865 0.45325 12.95422 0.41613 59136.970683 0.000822 0.30969 0.00831 0.99834 0 45.83953 0.59674 42.49036 0.55314 14.19619 0.33296 13.15897 0.30863
