/* ** ** 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 56052.939810 0.000437 0.11869 0.00915 0.99338 0 23.82061 0.59016 22.01659 0.54546 2.82721 0.20627 2.61307 0.19065 56052.940658 0.000411 0.12758 0.00969 0.97887 0 24.39577 0.61977 22.37900 0.56852 3.11247 0.22284 2.85744 0.20459 56052.941508 0.000440 0.12347 0.00959 0.99342 0 22.69983 0.57647 20.91022 0.53103 2.80273 0.20575 2.58423 0.18974 56052.942365 0.000417 0.13451 0.01033 1.00000 0 22.19339 0.58386 20.53349 0.54019 2.98513 0.21530 2.76187 0.19920 56052.943184 0.000402 0.13569 0.01060 1.00000 0 22.36171 0.59537 20.68919 0.55084 3.03428 0.22278 2.80733 0.20612 56052.944011 0.000425 0.12649 0.00978 0.99320 0 22.94060 0.58756 21.22481 0.54362 2.90169 0.21171 2.68466 0.19587 56052.944879 0.000443 0.12820 0.00986 0.99346 0 21.83744 0.56216 20.20419 0.52012 2.79952 0.20297 2.59014 0.18779 56052.945721 0.000399 0.13415 0.01023 1.00000 0 23.18942 0.61107 21.45505 0.56537 3.11081 0.22273 2.87815 0.20607 56052.946546 0.000425 0.12067 0.00937 1.00000 0 23.77692 0.59892 21.99859 0.55412 2.86914 0.21066 2.65455 0.19490 56052.947374 0.000402 0.13728 0.01059 0.96403 0 23.31609 0.61520 21.38355 0.56418 3.20092 0.23204 2.93807 0.21302 56052.948175 0.000399 0.14003 0.01071 0.99275 0 22.58860 0.60692 20.69848 0.55612 3.16309 0.22647 2.89916 0.20758 56052.948968 0.000394 0.13170 0.01018 1.00000 0 23.89826 0.62519 21.97095 0.57474 3.14742 0.22900 2.89679 0.21079 56052.950007 0.000645 0.13499 0.00808 0.99552 0 23.50598 0.48609 21.48082 0.44417 3.17303 0.17835 2.90026 0.16300
