/* ** ** 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 55664.806082 0.000443 0.13812 0.01073 0.98693 0 22.14112 0.59133 18.87101 0.50385 3.05807 0.22303 2.60678 0.18999 55664.806967 0.000443 0.12846 0.00996 0.99346 0 23.17666 0.59965 20.06824 0.51920 2.97734 0.21754 2.57645 0.18828 55664.807879 0.000469 0.13284 0.01020 0.96912 0 21.97459 0.57631 18.95972 0.49724 2.91904 0.21059 2.51748 0.18156 55664.808805 0.000457 0.12732 0.00986 0.98734 0 22.58356 0.57834 19.71643 0.50492 2.87536 0.21013 2.51039 0.18345 55664.809696 0.000434 0.13805 0.01056 0.99333 0 22.38544 0.59849 19.28089 0.51552 3.09036 0.22143 2.66476 0.19092 55664.810746 0.000616 0.12777 0.00989 0.73571 0 22.60697 0.57657 19.58847 0.49956 2.88855 0.21110 2.49907 0.18263 55664.811782 0.000420 0.14143 0.01102 0.97931 0 22.60762 0.61120 19.50383 0.52725 3.19746 0.23368 2.75790 0.20154 55664.812650 0.000448 0.13787 0.01076 0.98065 0 21.67928 0.57834 18.69139 0.49867 2.98897 0.21931 2.57773 0.18912 55664.813489 0.000391 0.15617 0.01207 0.98519 0 22.12278 0.62489 19.14457 0.54071 3.45502 0.24858 2.98679 0.21485 55664.814291 0.000411 0.14518 0.01170 0.98592 0 21.71942 0.60605 18.81609 0.52504 3.15329 0.23828 2.73268 0.20645 55664.815318 0.000616 0.14059 0.00913 1.00000 0 21.78180 0.49010 18.92349 0.42577 3.06236 0.18648 2.65960 0.16196
