/* ** ** 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 57776.201891 0.000394 0.19882 0.01651 0.99265 0 22.39093 0.74611 14.59170 0.47289 4.45182 0.33865 2.88530 0.21255 57776.202638 0.000353 0.22173 0.01784 1.00000 0 22.43476 0.77042 14.52142 0.49777 4.97443 0.36187 3.22322 0.23422 57776.203428 0.000437 0.20453 0.01660 0.98013 0 21.35426 0.70507 12.80443 0.42269 4.36762 0.32385 2.61930 0.19429 57776.204235 0.000370 0.24166 0.01939 0.97656 0 21.61602 0.76539 13.14814 0.46556 5.22362 0.37608 3.17676 0.22867 57776.204976 0.000370 0.23733 0.01957 0.99219 0 21.35853 0.76674 12.88339 0.46250 5.06896 0.37621 3.05241 0.22642 57776.205728 0.000382 0.23029 0.01857 0.99242 0 21.62389 0.75573 13.05142 0.45602 4.97982 0.36184 3.00177 0.21812 57776.206498 0.000388 0.21994 0.01773 0.97015 0 22.88907 0.77584 13.70193 0.46446 5.03424 0.36825 3.01057 0.22027 57776.207296 0.000411 0.20453 0.01646 0.99296 0 22.49257 0.73794 13.56987 0.44522 4.60049 0.33797 2.77673 0.20401 57776.208109 0.000402 0.21181 0.01711 0.99281 0 22.17584 0.74380 13.40557 0.44961 4.69708 0.34508 2.83709 0.20844 57776.208911 0.000399 0.21560 0.01743 0.97101 0 22.38517 0.74580 13.48035 0.44912 4.82618 0.35555 2.90683 0.21414 57776.209730 0.000420 0.21234 0.01679 0.97241 0 22.10620 0.72394 13.24141 0.43362 4.69405 0.33788 2.81627 0.20272 57776.210549 0.000399 0.22648 0.01785 1.00000 0 21.52677 0.73587 12.82232 0.43828 4.87539 0.34626 2.90443 0.20625 57776.211613 0.000666 0.21958 0.01427 0.99130 0 20.22651 0.56200 12.02347 0.33409 4.44131 0.26083 2.63978 0.15499
